-本文档为 STM32G070RB-Nucleo 开发板的 BSP (板级支持包) 说明。
|
|
|
+## MCU: STM32G070RB @64MHz, 128KB FLASH, 36KB RAM
|
|
|
|
|
|
-主要内容如下：
|
|
|
+The STM32G070CB/KB/RB mainstream microcontrollers are based on high-performance Arm® Cortex®-M0+ 32-bit RISC core operating at up to 64 MHz frequency. Offering a high level of integration, they are suitable for a wide range of applications in consumer, industrial and appliance domains and ready for the Internet of Things (IoT) solutions.

+The devices incorporate a memory protection unit (MPU), high-speed embedded memories (128 Kbytes of Flash program memory with read protection, write protection, and 36 Kbytes of SRAM), DMA and an extensive range of system functions, enhanced I/Os and peripherals. The devices offer standard communication interfaces (two I2Cs, two SPIs / one I2S, and four USARTs), one 12-bit ADC (2.5 MSps) with up to 19 channels, a low-power RTC, an advanced control PWM timer, five general-purpose 16-bit timers, two basic timers, two watchdog timers, and a SysTick timer.
|
|
|
+The devices operate within ambient temperatures from -40 to 85°C. They can operate with supply voltages from 2.0 V to 3.6 V. Optimized dynamic consumption combined with a comprehensive set of power-saving modes allows the design of low-power applications.
|
|
|
+VBAT direct battery input allows keeping RTC and backup registers powered.
|
|
|
+The devices come in packages with 32 to 64 pins.

|
|
|
- 本章节是为需要在 RT-Thread 操作系统上使用更多开发板资源的开发者准备的。通过使用 ENV 工具对 BSP 进行配置，可以开启更多板载资源，实现更多高级功能。

|
|
-### 快速上手
|
|
|
-
|
|
|
-本 BSP 为开发者提供 MDK5 和 IAR 工程，并且支持 GCC 开发环境。下面以 MDK5 开发环境为例，介绍如何将系统运行起来。
|
|
|
-
|
|
|
-#### 硬件连接
|
|
|
-
|
|
|
-使用数据线连接开发板到 PC，打开电源开关。
|
|
|
-
|
|
|
-#### 编译下载
|
|
|
-
|
|
|
-双击 project.uvprojx 文件，打开 MDK5 工程，编译并下载程序到开发板。
|
|
|
-
|
|
|
-> 将工程使用的仿真器设置为ST-Link并安装仿真器好驱动程序以后，将开发板连接到PC，点击下载按钮即可下载程序到开发板。
|
|
|
-
|
|
|
-#### 运行结果
|
|
|
-
|
|
|
-下载程序成功之后，系统会自动运行。
|
|
|
-
|
|
|
-连接开发板对应串口到 PC , 在终端工具里打开相应的串口（115200-8-1-N），复位设备后，可以看到 RT-Thread 的输出信息:

|
|
|

|
|
|
-### 进阶使用
|
|
|
-
|
|
|
-此 BSP 默认只开启了 GPIO 和 UART 的功能，如果需使用 SPI，I2C 等更多高级功能，需要利用 ENV 工具对BSP 进行配置，步骤如下：
|
|
|
-
|
|
|
-1. 在 bsp 下打开 env 工具。
|
|
|
-
|
|
|
-2. 输入`menuconfig`命令配置工程，配置好之后保存退出。
|
|
|
-
|
|
|
-3. 输入`pkgs --update`命令更新软件包。
|
|
|
-
|
|
|
-4. 输入`scons --target=mdk5/iar` 命令重新生成工程。
