+# Cypress CSDIDAC Middleware Library
+
+### Overview
+The CSDIDAC provides an API that allows the CSD HW block IDAC functionality.
+It can be useful for devices that do not include other DAC options. 
+
+### Features
+* A two-channel IDAC with the 7-bit resolution
+* The IDAC A and IDAC B channels can be enabled/disabled independently
+* The IDAC A and IDAC B channels can be configured with sourcing/sinking current independently
+* The IDAC A and IDAC B channels can be joined to increase a maximum output current
+* The IDAC A and IDAC B channels can be enabled/disabled simultaneously by using the CY_CSDIDAC_AB option
+* The 0 to 609.6 uA (609600 nA) current range is available for each IDAC channel
+* Each IDAC can use independently one of the six available LSB depending on a desired output current
+
+### Quick Start
+The CSDIDAC could be configured by the ModusToolbox CSD personality. Refer to the [API Reference Guide Configuration Considerations](https://cypresssemiconductorco.github.io/csdidac/csdidac_api_reference_manual/html/index.html#group_csdidac_configuration).

+/**
+* \mainpage CSDIDAC Middleware Library
+*
+* The CSDIDAC middleware is the IDAC solution that uses the
+* CSD HW block. Any GPIO that can be connected to AMUX-A/B (refer to the
+* particular device datasheet for information) can be an CSDIDAC output
+* under software control.
+* The CSD HW block is mainly used to implement the touch sense applications and
+* proximity sensors (refer to the
+* <a href="https://cypresssemiconductorco.github.io/capsense/capsense_api_reference_manual/html/index.html">
+* <b>CapSense Middleware API Reference Guide</b></a>), but can also
+* be used to implement the IDAC, which is especially useful for the devices that
+* do not include another hardware option to implement IDAC.
+*
+* <b>Features:</b>
+* * A two-channel IDAC with the 7-bit resolution.
+* * The IDAC A and IDAC B channels can be enabled/disabled independently.
+* * The IDAC A and IDAC B channels can be configured with sourcing/sinking
+*   current independently.
+* * The IDAC A and IDAC B channels can be joined to increase a maximum output
+*   current.
+* * The IDAC A and IDAC B channels can be enabled/disabled simultaneously
+*   by using the CY_CSDIDAC_AB option.
+* * The 0 to 609.6 uA (609600 nA) current range is available for each IDAC
+*   channel.
+* * Each IDAC can use independently one of the six available LSB depending
+*   on a desired output current:
+*
+* <table class="doxtable">
+*   <tr><th>LSB Index</th><th>LSB</th><th>Available Current Range</th></tr>
+*   <tr>

+*     <td>0 to 4762.5 nA</td>

+*
+* Include cy_csdidac.h to get access to all functions and other declarations in
+* this library.
+* The \ref section_csdidac_quick_start is offered in this API Reference Guide.
+*
+* Refer to the \ref section_csdidac_toolchain for the compatibility
+* information.
+*
+* Refer to the \ref group_csdidac_changelog for the differences between the

+* \ref group_csdidac_changelog also describes the impact of changes to

+*
+* The CSD HW block enables the multiple sensing capabilities on PSoC devices
+* including the self-cap and mutual-cap capacitive touch sensing solution,
+* 10-bit ADC, IDAC, and Comparator. The CSD driver is a low-level
+* peripheral driver, a wrapper to manage access to the CSD HW block.
+* Any middleware access to the CSD HW block is through the CSD Driver.
+*
+* The CSD HW block can support only one function at a time. However, all
+* supported functionality (like CapSense, CSDADC, CSDIDAC, etc.) can be
+* time-multiplexed in a design. I.e. you can save the existing state
+* of the CapSense middleware, restore the state of the CSDIDAC middleware,
+* perform DAC operations, and then switch back to the CapSense functionality.
+* For more details and code examples, refer to the description of the
+* Cy_CSDIDAC_Save() and Cy_CSDIDAC_Restore() functions.

+* \image latex capsense_solution.png
+*
+* This section describes only the CSDIDAC middleware. Refer to the corresponding
+* sections for documentation of other middleware supported by the CSD HW block.
+* The CSDIDAC library is designed to be used with the CSD driver.
+* The application program does not need to interact with the CSD driver
+* and/or other drivers such as GPIO or SysClk directly. All of that is
+* configured and managed by the middleware.
+*
+* The Cy_CSDIDAC API is described in the following sections:
+* * \ref group_csdidac_macros
+* * \ref group_csdidac_data_structures
+* * \ref group_csdidac_enums
+* * \ref group_csdidac_functions
+*
+********************************************************************************
+* \section section_csdidac_quick_start Quick Start Guide
+********************************************************************************
+*
+* The CSDIDAC middleware can be used in various Development Environments
+* such as ModusToolbox, MBED, etc. Refer to the \ref section_csdidac_toolchain.
+* The quickest way to get started is using the Code Examples.
+* The continually expanding portfolio of the code examples is available
+* at the <a href="http://www.cypress.com"><b>Cypress Semiconductor website</b></a>
+* and on <a href="https://github.com/cypresssemiconductorco">
+* <b>GitHub</b></a>.
+*
+* This quick start guide assumes that the environment is configured to use the
+* PSoC 6 Peripheral Driver Library(psoc6pdl) for development and the
+* PSoC 6 Peripheral Driver Library(psoc6pdl) is included in the project.
+*
+* The steps required to set up the CSDIDAC and get the
+* desired current:
+*
+* 1. Set up the CSDIDAC configuration manually or by using the Device Configurator
+*    as described in the \ref section_csdidac_configuration section.
+* \note
+* Put the CSDIDAC name to the Alias field of the CSD resource if the
+* Device Configurator is used.
+*
+* 2. Include cy_csdidac.h to get access to all CSDIDAC API and cy_pdl.h to get
+*    access to API of peripheral drivers according to the example below:
+* \snippet csdidac/snippet/main.c snippet_required_includes
+* 3. If you use the MBED OS, include the cycfg.h file to get access to the
+*    System Configuration:
+* \snippet csdidac/snippet/main.c snippet_mbed_required_includes
+* 4. Declare the 'cy_csdidac_context' variable as per example below:
+* \snippet csdidac/snippet/main.c snippet_csdidac_context_declaration
+* 5. Update the main() routine with the following code:
+* \snippet csdidac/snippet/main.c snippet_Cy_CSDIDAC_Usage
+*
+********************************************************************************
+* \section section_csdidac_configuration Configuration Considerations
+********************************************************************************
+*
+* The CSDIDAC middleware operates on the top of the CSD Driver included in the
+* PSoC 6 Peripheral Driver Library (psoc6pdl). Refer to the "CSD(CapSense
+* Sigma Delta)" section of the PSoC 6 Peripheral Driver Library (psoc6pdl) API
+* Reference Manual.
+* This section guides how to set up the CSDIDAC middleware for the operation
+* with the following parameters:
+* 1. Device VDDA: 3.3V.
+* 2. Device Peri Clock frequency: 48MHz.
+* 3. IDAC A is sourcing current of 50 uA to GPIO pin P0[4].
+* 4. IDAC B is sinking current of 0.5uA from GPIO pin P0[5].
+*
+* There are two methods for the CSDIDAC Middleware configuration:
+* 1. \ref subsection_csdidac_mtb_configuring
+* 2. \ref subsection_csdidac_manual_configuring
+*
+* Generation of the initialization code using the
+* <a href="https://www.cypress.com/ModusToolboxDeviceConfig">
+* <b>ModusToolbox Device Configurator Tool </b></a> which is part of the
+* <a href="https://www.cypress.com/products/modustoolbox-software-environment">
+* <b>ModusToolbox</b></a>, greatly simplifies the PSoC configuration.
+* The <a href="https://www.cypress.com/ModusToolboxDeviceConfig"><b>ModusToolbox
+* Device Configurator Tool </b></a> provides the user interface to set up and
+* automatically generate the initialization code (including analog routing) and
+* configuration structures.
+*
+* Manual implementation of the initialization code (including analog routing)
+* and configuration structures is recommended for expert Users only. This will
+* include the code for the following settings which in case of the
+* Device Configurator usage are generated automatically based upon the settings
+* entered in its UI:
+*  * Assigning the Peripheral Clock Divider.
+*  * Configuring the HSIOM_AMUX_SPLIT_CTL switches to route signal from input
+*    pins configured as the CSDIDAC channels to the CSD HW block.
+*  * Declaration and initialization of the CSDIDAC configuration structure.
+*  * Declaration and initialization of the CSD HW driver context structure.
+*  * Definition of the of the CSD HW block base address.

+********************************************************************************
+* \subsection subsection_csdidac_mtb_configuring Use ModusToolbox Device Configurator Tool to generate initialization code
+********************************************************************************
+*
+* The steps required to generate the initialization code using the
+* <a href="https://www.cypress.com/ModusToolboxDeviceConfig">
+* <b>ModusToolbox Device Configurator Tool </b></a>:
+* 1. Launch the ModusToolbox Middleware Selector and enable the CSD IDAC
+*    middleware. This step is required only if the ModusToolbox IDE is used.
+*    Otherwise, ensure the CSDIDAC Middleware is included in your project.
+* 2. Launch the ModusToolbox Device Configurator Tool.
+* 3. Switch to the System tab. Configure the CLK_PERI frequency to achieve 48MHz
+*    (you may need to change the FLL or PLL frequency) and set the VDDA voltage
+*    to 3.3V in Power/MCU Personality.
+* 4. Switch to the Peripherals tab (#1 in the figure below). Enable the
+*    CSD personality under System (#2 in the figure below) and
+*    enter Alias (#3 in the figure below). We use CSDIDAC in
+*    \ref section_csdidac_quick_start.
+* 5. Go to the Parameters pane and configure the CSD Personality:

+********************************************************************************
+* \subsection subsection_csdidac_manual_configuring Implement the initialization code manually
+********************************************************************************
+*
+* The steps required to implement the initialization code manually:
+* 1. Launch the ModusToolbox Middleware Selector and enable the
+*    CSD IDAC middleware. This step is required only if the ModusToolbox IDE
+*    is used.
+*    Otherwise, ensure the CSDIDAC Middleware is included in your project.
+* 2. Define the CSD HW block base address. See the code example below:
+* \snippet csdidac/snippet/main.c snippet_csd_hw_definition
+* 3. Declare the CSD HW driver context structure and initialize the
+*    lockKey field with the CY_CSD_NONE_KEY value. See the code example below:
+* \snippet csdidac/snippet/main.c snippet_csd_context_declaration
+* 4. Declare the CSDIDAC configuration structure and initialize it according
+*    to the desired parameters. See the code example below:
+* \snippet csdidac/snippet/main.c snippet_csdidac_config_declaration
+* 5. Assign the Peripheral Clock Divider to the CSD HW block and configure
+*    the divider value.
+*    See the code example below and refer to the main() routine code snippet in
+*    \ref section_csdidac_quick_start
+* \snippet csdidac/snippet/main.c snippet_Cy_CSDIDAC_Clock_Assignment
+* 6. Set the configuration of the HSIOM_AMUX_SPLIT_CTL switches to route signal
+*    from CSD HW block to the pins configured as the CSDIDAC output channels.
+*
+*    The AMUX bus has segments that are separated with the HSIOM_AMUX_SPLIT_CTL switches.
+*    The code below closes the AMUX_SPLIT_CTL switches, which route the IDAC output
+*    signal from the CSD block to the pin. In this example, IDAC output channels
+*    are assigned to the P0[4] and P[5] pins. The AMUX_SPLIT_CTL[5] and AMUX_SPLIT_CTL[6]
+*    switches must be closed in the PSoC6 device. The P0[4] and P[5] pins in the
+*    PSoC4 device belong to the AMUX bus segment, which is connected to the CSD block
+*    directly. In this case, the AMUX_SPLIT_CTL switches are not closed.
+*    Refer to the
+*    <a href="http://www.cypress.com/trm218176"><b>Technical Reference Manual
+*    (TRM)</b></a> for more information regarding the analog interconnection.
+*    See the code example below and refer to the main() routine code snippet in
+*    \ref section_csdidac_quick_start
+* \snippet csdidac/snippet/main.c snippet_Cy_CSDIDAC_Amux_Configuration
+* \note
+* If you use a KIT, check on the schematics, if pins P0[4] and P0[5] are
+* free. If not, use some other pins and update the AMUX_SPLIT_CTL registers.
+* \note
+* Some CSDIDAC configurations are restricted. The CSD personality has a
+* mechanism to prevent writing an invalid configuration. If CSDIDAC is manually
+* created, avoid the following combinations:
+*  * both IDAC channels are disabled
+*  * one IDAC channel is disabled and another channel is joined to it
+*  * the IDAC A channel and IDAC B channel are joined to each other
+*
+* Refer to \ref section_csdidac_quick_start section for the application layer
+* code required to set up the CSDIDAC and to get the desired current on the
+* assigned pin.

+********************************************************************************
+* \section group_csdadc_use_cases Use Cases
+********************************************************************************
+*
+* This section provides descriptions and links to additional documentation for
+* some specific CSDIDAC use cases.
+*
+********************************************************************************
+* \subsection group_csdidac_low_power_design Low power design
+********************************************************************************
+* The CSD HW block and CSDIDAC middleware can operate in CPU active and
+* CPU sleep power modes. It is also
+* possible to switch between low power and ultra low power system modes.
+* In System Deep Sleep and Hibernate power modes, the CSD HW block is powered off and
+* CSDIDAC operations are not performed. Before entering CPU / System Deep Sleep,
+* disable CSDIDAC output current generation. If output
+* currents are not disabled, a CPU Deep Sleep transition will fail.
+* When the device wakes up from CPU / System Deep Sleep, the CSD HW block resumes operation
+* without the need for re-initialization and the CSDIDAC operations can be
+* continued with configuration that was set before a CPU / System Deep Sleep transition.
+* When the device wakes up from Hibernate power mode, the CSD HW block
+* does not retain the configuration and CSDIDAC requires re-initialization.
+*
+* \note
+* 1. Analog start up time for the CSD HW block is 25 us for PSoC6 devices and
+*    10 us for PSoC4 devices. Initiate any kind of operation only after 25 us
+*    for PSoC6 devices and 10 us for PSoC4 devices from System Deep Sleep / Hibernate exit.
+*
+* 2. Entering CPU Deep Sleep mode does not mean the device enters
+*    System Deep Sleep. For more detail about switching to System Deep Sleep,
+*    refer to the device TRM.
+*
+* Refer to the Cy_CSDIDAC_DeepSleepCallback() function description and to the
+* SysPm (System Power Management) driver documentation for the low power design
+* considerations.
+*
+* <b>Sleep mode</b><br>
+* The CSD HW block can operate in CPU sleep mode. The user can start CSDIDAC
+* and move CPU into sleep mode to reduce power consumption. After wake-up CPU
+* from sleep, the user can perform other operations, e.g. disable IDACs.
+* Then, the user configures the CSDIDAC middleware as described in
+* \ref section_csdidac_configuration, and updates the main() routine with
+* the following code:
+* \snippet csdidac/snippet/main.c snippet_Cy_CSDIDAC_Sleep
+*
+* <b>Deep Sleep mode</b><br>
+* To use the CSDIDAC middleware in CPU / System Deep Sleep mode, the user configures
+* a wake-up source (e.g. a pin, WDT, LPC or another entities, that are active
+* in CPU / System Deep Sleep mode), configures the CSDIDAC middleware as described in
+* \ref section_csdidac_configuration, configures CSDIDAC and other drivers' and
+* middleware's (if present) Deep Sleep Callback structures, registers
+* callbacks, and updates the main() routine with the following code:
+* \snippet csdidac/snippet/main.c snippet_CSDIDAC_DeepSleep_structures
+* \snippet csdidac/snippet/main.c snippet_Cy_CSDIDAC_DeepSleep

+# USB Device Middleware Library
+
+## Overview
+
+The USB Device middleware provides a full-speed
+[USB 2.0 Chapter 9 specification](https://usb.org/document-library/usb-20-specification)
+compliant device framework. It uses the USBFS driver from
+CAT1A/CAT2 Peripheral Driver Library to interface with the hardware.
+The middleware provides support for Audio, CDC, HID and Vendor classes.
+It also enables implementing support for other classes. The USB Configurator
+tool makes it easy to construct a USB Device descriptor.
+
+## Features
+
+* USB Full-Speed Device Framework
+* USB Device Configurator
+* The following USB Classes are supported:
+  * Audio Class
+  * CDC: Communication Device Class
+  * HID: Human Interface Device
+* Adding Custom Class Support
+* Vendor-Specific Requests Support
+* Power Status Reporting for Self-Powered Devices
+* Blocking API Timeout Function Redefinition
+* Compliance with [MISRA-C:2012 coding standard](https://www.misra.org.uk/)
+
+## USB Device Specific Instructions
+
+The user must ensure that the parameters selected in the USB Device personality
+are aligned with the descriptor configuration in the USB Configurator, because
+there is no connection between the USB Device personality in the Device
+Configurator and USB Configurator.
+
+Specifically, parameter "Endpoints Mask" in the USB personality must be aligned
+with the endpoints selected in the USB Configurator. If DMA Automatic mode is
+selected, parameter  "Endpoint Buffer Size" must be aligned with the total size
+of the endpoint buffers allocated in the USB Configurator.
+
+## Quick Start
+
+Configure the USB Device using the ModusToolbox™ USB Device personality and
+USB Device Configurator. Refer to the
+[API Reference Quick Start Guide](https://infineon.github.io/usbdev/usbfs_dev_api_reference_manual/html/index.html)

+# USB Device Middleware Library 2.10
+
+## What's Included?
+
+For a complete description of the USB Device Middleware, refer to
+[README.md](./README.md) and the
+[USB Device API Reference](https://infineon.github.io/usbdev/usbfs_dev_api_reference_manual/html/index.html).
+The revision history of the USB Device Middleware is also available in the
+[API Reference Changelog](https://infineon.github.io/usbdev/usbfs_dev_api_reference_manual/html/index.html#group_usb_dev_changelog).
+
+New in this release:
+
+* Updated the middleware to support configurations without any data endpoints.
+* Added support for the PMG1 Family of MCUs.
+* Updated the middleware to comply with MISRA-C:2012 standard.
+
+## Defect Fixes
+
+* Fixed an issue in vendor class request handling.
+
+## USB Device Specific Instructions
+
+The user must ensure that the parameters selected in the USB Device personality
+are aligned with the descriptor configuration in the USB Configurator, because
+there is no connection between the USB Device personality in the Device
+Configurator and USB Configurator.
+
+Specifically, parameter "Endpoints Mask" in the USB personality must be aligned
+with the endpoints selected in the USB Configurator. If DMA Automatic mode is
+selected, parameter  "Endpoint Buffer Size" must be aligned with the total size
+of the endpoint buffers allocated in the USB Configurator.
+
+## Known Issues
+
+| Problem | Workaround |
+| ------- | ---------- |
+| The USB Device ignores LPM requests after wake up from Deep Sleep. | Call USBFS driver Cy_USBFS_Dev_Drv_Lpm_SetResponse() after calling Cy_USBFS_Dev_Drv_Resume() to restore response to the LPM packets. |
+| The USB Device modes with DMA do not work after wake up from Deep Sleep, due to incorrect restore of the ARB_CFG register. | Save ARB_CFG values before entering Deep Sleep and restore it after calling of Cy_USBFS_Dev_Drv_Resume. |
+
+## Supported Software and Tools
+
+This version of the USB Device Middleware was validated for compatibility with the following Software and Tools:

+/**
+* \mainpage USB Device Middleware Library 2.10
+*
+* The USB Device middleware provides a full-speed USB 2.0 Chapter 9 specification
+* -compliant device framework. It uses the USBFS driver from PDL to interface
+* with the hardware. The middleware provides support for Audio, CDC, and HID
+* classes. Also, it allows implementing other class support.
+* The USB Configurator tool makes it easy to construct the USB
+* Device descriptor.
+*
+* <b>Features:</b>
+* * USB Full-Speed Device Framework
+* * \ref group_usb_dev_cfg_tool
+* * The following USB Classes are supported:
+*   * \ref group_usb_dev_audio_class_info
+*   * \ref group_usb_dev_cdc_class_info
+*   * \ref group_usb_dev_hid_class_info
+*
+********************************************************************************
+* \section section_usb_dev_general General Description
+********************************************************************************
+*
+* The USB Device structure is divided into  layers. The implementation
+* is event-driven: the USBFS driver receives interrupts from the hardware and
+* provides callbacks to the USB Device layer which implements them and provides
+* events to the Class layer. A simplified image is shown below. \n \n
+* \image html usb_dev_solution_struct.png
+*
+* Include cy_usb_dev.h along with the header for the USB class to be used
+* (cy_usb_dev_hid.h, cy_usb_dev_cdc.h, cy_usb_dev_audio.h) to get access to
+* all the functions and other declarations in this library.
+* If you use ModusToolbox USB Device Configurator, also include cycfg_usbdev.h.
+*
+********************************************************************************
+* \section section_usb_dev_quick_start Quick Start Guide
+********************************************************************************
+*
+* Cypress USB Device middleware can be used in various software environments.
+* Refer to the \ref section_usb_dev_toolchain.
+* The quickest way to get started is using the Code Examples.
+* Cypress Semiconductor continuously extends its portfolio of code examples
+* at <a href="http://www.cypress.com"><b>Cypress Semiconductor website</b></a>
+* and at <a href="https://github.com/cypresssemiconductorco">
+* <b>Cypress Semiconductor GitHub</b></a>.
+*
+* This quick start guide is for an environment configured to use for development
+* MTB CAT1A Peripheral Driver Library (PSoC6) or MTB CAT2 Peripheral Driver Library
+* (PSoC4 & PMG1) included in the project.
+*
+* To easily run a USB, use the ModusToolbox USBCommDevice or USBM project.
+* The steps below show how to set up a USB Device based on a basic
+* ModusToolbox project (like Hello_World).
+*
+* The following steps set up a USB device recognized as an standard HID device -
+* USB mouse and moves it from right to the left, and vice-versa.
+* \note Some steps contain a corresponding to the figure below number in
+* brackets.
+*
+* \subsection subsection_qsg_step1 STEP 1: Enable the USB Device middleware.
+*
+* Launch ModusToolbox Library Manager and enable the USB Device middleware.
+* This step is required only if the ModusToolbox IDE is used. Otherwise, ensure
+* the USB Device Middleware is included in your project.
+*
+* \subsection subsection_qsg_step2 STEP 2: Generate initialization code.
+*
+* 1.  Launch the ModusToolbox Device Configurator Tool and switch to the
+*     Peripherals tab (#1.1).
+* 2.  Enable the USB personality under Communication and enter Alias (#1.2).
+*     We use USBHID in \ref section_usb_dev_quick_start
+* 3.  Go to the Parameters pane and configure the USB personality: assign
+*     the peripheral clock divider (#1.3) for Clock (Bus Reset).
+*     Any available free divider can be used.
+*     This is not required to be done for the PMG1 family of devices.
+* 4.  Set Endpoint Mask to 1 to enable data endpoint 1 (#1.4) Enabled data
+*     endpoints must match the descriptor tree in the USB Configurator.
+*     \image html usb_dev_device_cfg.png
+* 5.  Switch to the System tab (#2.1).
+* 6.  Check the IMO clock is enabled (#2.2). Select Trim with USB (#2.3)
+* 7.  Select one of the PLLs, if your device supports more than one.
+*     Enable the PLL and set a frequency of 48 MHz (#2.4).
+* 8.  Select the CLK_HF3 USB clock (#2.5). Assign the source clock to
+*     the CLK_PATH connected to the configured previously PLL.<br>
+*     (Not required for PMG1 devices) (#2.6).
+* 9.  Check the FLL clock is enabled (Not required for PMG1 devices) (#2.7).
+* 10. Select File->Save to generate initialization code.

+********************************************************************************
+*
+* There are many possible use cases for HID depending on the end application.
+* A keyboard/keypad is a common HID application that has been implemented
+* previously with PSoC. Additionally, customers can use PSoC to implement a
+* PC mouse or game controller device. A more generic use case seen is with
+* regards to customers using USB as general-purpose interface between PSoC and
+* the Host, without conforming to specific USAGE such as a Keyboard, Mouse, etc.
+* Instead the user configures the HID descriptor to be a generic device, which
+* allows them to transfer Vendor-Specific information, such as ADC data,
+* button presses, etc., across the HID protocol. This allows customers to
+* perform custom/generic data transfers over USB, without needing to provide
+* an INF or SYS file during enumeration or worry about WHQL certification.
+* All this is accomplished using the HID drivers that are built into all

+* \subsection group_usb_dev_class_x Adding Custom Class
+********************************************************************************
+*
+* The USB Device middleware provides API interface that allows the user to
+* implement custom class support. The middleware notifies registered class about
+* following events:
+* * Bus Reset detected ( \ref cy_cb_usb_dev_bus_reset_t ).
+* * Set Configuration request received ( \ref cy_cb_usb_dev_set_config_t ).
+* * Set Interface request received ( \ref cy_cb_usb_dev_set_interface_t ).
+* * Setup packet received ( \ref cy_cb_usb_dev_request_received_t ).
+* * Data is received in response for current setup packet ( \ref cy_cb_usb_dev_request_cmplt_t ).
+*
+* To create a new custom Class, follow the steps below:
+* 1. Implement functions to service events (from the list above) required
+*    for class operation. Typically, class should implement service of class-specific
+*    requests therefore needs to implement functions defined by \ref cy_cb_usb_dev_request_received_t
+*    and \ref cy_cb_usb_dev_request_cmplt_t.
+* 2. Initialize instance of \ref cy_stc_usb_dev_class_t structure using implemented
+*    service functions. Provide NULL pointer as function pointer if class does not
+*    use this event.
+* 3. Allocate instance of \ref cy_stc_usb_dev_class_ll_item_t structure to
+*    provide storage for a linked list item of the class.
+* 4. The class might need a context to store class-specific data. If needed,
+*    define context type specific for this class and allocate it.
+* 5. To enable class operation, this needs to be registered using
+*    \ref Cy_USB_Dev_RegisterClass function after USB Device middleware is
+*    initialized.
+*
+* Any of supported classes can be taken as an example to implement a custom class.
+*
+********************************************************************************

+*
+* The vendor-specific requests are STALLed by USB Device middleware by default.
+* The exception is MS OS String vendor-specific request to retrieve an OS Feature
+* Descriptor (Note that USB device must contain MS OS String descriptor to handle

+* \subsection group_usb_dev_ep_buf_alloc Allocate Data Endpoint Buffer
+********************************************************************************
+*
+* The application allocates buffers for data endpoints to operate. The buffer
+* allocation depends on USBFS driver endpoint buffer access type configuration.
+* It specifies which hardware register set 8-bit or 16-bit is used to access
+* hardware endpoints buffer. The 16-bit access requires that the specific rules for
+* the endpoints buffer allocation must be met (See Hardware Buffer Access
+* section of the USBFS driver for more information). \n
+* To make endpoint buffer allocation configuration independent, use

+********************************************************************************
+*
+* The USB Device responds to GET_STATUS requests based on the status set with
+* the \ref Cy_USB_Dev_SetPowerStatus function. To set the correct status,
+* \ref Cy_USB_Dev_SetPowerStatus must be called during initialization if USB
+* Device is configured as self-powered. The \ref Cy_USB_Dev_SetPowerStatus must
+* be called any time the device changes status. A self-powered device also requires
+* monitoring VBUS to control pull-up resistors. The pull-up resistor does
+* not supply power to the data line until you call \ref Cy_USB_Dev_Connect.
+* \ref Cy_USB_Dev_Disconnect disconnects the pull-up resistor from the data line.

+* The USB Device middleware provides following blocking functions: \ref Cy_USB_Dev_ReadEpBlocking,
+* \ref Cy_USB_Dev_WriteEpBlocking, and \ref Cy_USB_Dev_Connect (the behavior
+* defined by the blocking parameter of the connect function). The blocking functions
+* parameter timeout defines how many milliseconds to wait before timeout.
+* The SysLib driver function Cy_SysLib_Delay is used to implement a 1 millisecond
+* wait cycle. The middleware provides function \ref Cy_USB_Dev_OverwriteHandleTimeout
+* that allows overriding the wait function implementation. This might be

+### 使用 MDK V5 开发
 
 #### 硬件连接
 
 使用数据线连接开发板到 PC。
 
 #### 编译下载
+
 1、配置工程：
 
 首先打开 MDK ，若没有安装 `Cypress-PSoC6` 的芯片支持包会提示在线安装，根据提示安装即可。若受网络问题，可以进入 [keil](https://www.keil.com/dd2/pack) 官网下载安装包，离线安装。

 3、下载此工程：
 
-
 工程默认配置使用板载 `DAP-LINK` 使用 `SWD` 方式下载程序，使用数据线连接开发板，编译之后直接点击下载按钮即可。
 
-#### 运行结果
+### 使用 RT-Thread Studio 开发
+
+#### 导入工程
+
+* 首先打开  `RT-Thread Studio` 开发工具，点加左上角文件—>导入—> RT-Thread Studio项目到工作空间中。
+
+![](./figures/studio1.png)
+
+* 接着选择 `PSoC6 CY8CKIT-062S2-43012` 开发板支持包的目录，进行导入。
+
+![](./figures/studio2.png)
+
+#### 编译下载
+
+* 点击 IDE 左上角的构建选项进行工程的编译。
+
+![](./figures/studio3-build.png)
+
+* 当编译无错误警告时，点击 `Debug` 或 `Download` 选项进行调试/下载。
+
+  注：若点击下载并下载成功后串口终端无显示信息，请手动按下复位按键进行重启运行。
+
+  ![](./figures/studio4-download.png)
+
+## 运行结果
 
 下载程序成功之后，系统会自动运行。打开终端工具串口助手，选择波特率为 115200。复位设备后，LED 将会以 500HZ 的频率闪烁，而且在终端上可以看到 `RT-Thread` 的输出信息：
 
 注：推荐使用串口调试助手如：`MobaXterm`
