STM32L431-BearPi开发板的Arduino生态兼容说明

1 RTduino - RT-Thread的Arduino生态兼容层

STM32L431-BearPi开发板已经完整适配了RTduino软件包,即RT-Thread的Arduino生态兼容层。用户可以按照Arduino的编程习惯来操作该BSP,并且可以使用大量Arduino社区丰富的库,是对RT-Thread生态的极大增强。更多信息,请参见RTduino软件包说明文档

1.1 如何开启针对本BSP的Arduino生态兼容层

Env 工具下敲入 menuconfig 命令,或者 RT-Thread Studio IDE 下选择 RT-Thread Settings:

Hardware Drivers Config --->
    Onboard Peripheral Drivers --->
        [*] Compatible with Arduino Ecosystem (RTduino)

2 Arduino引脚排布

bearpi-l431-pinout

该BSP遵照E53接口的引脚排列方式,详见 pins_arduino.cpins_arduino.h

Arduino引脚编号 STM32引脚编号 5V容忍 备注
0 (D0) PA1 SPI-SCK,默认被RT-Thread的SPI设备框架spi1接管
1 (D1) PA4 SPI-SS,默认被RT-Thread的SPI设备框架spi1接管
2 (D2) PA0
3 (D3) PB9
4 (D4) PB8 PWM16-CH1,默认被RT-Thread的PWM设备框架pwm16接管
5 (D5) PB6 I2C-SCL,被RT-Thread的I2C设备框架i2c1总线接管
6 (D6) PB7 I2C-SDA,被RT-Thread的I2C设备框架i2c1总线接管
7 (D7) PA6 SPI-MISO,默认被RT-Thread的SPI设备框架spi1接管
8 (D8) PA12 SPI-MOSI,默认被RT-Thread的SPI设备框架spi1接管
9 (D9) PC9
10 (D10) PC4 Serial3-Tx,默认被RT-Thread的UART设备框架uart3接管
11 (D11) PC5 Serial3-Rx,默认被RT-Thread的UART设备框架uart3接管
12 (D12) PA8 PWM1-CH1,默认被RT-Thread的PWM设备框架pwm1接管
A0 PC2 ADC1-CH3,默认被RT-Thread的ADC设备框架adc1接管
DAC0 PA5 DAC1-CH2,默认被RT-Thread的DAC设备框架dac1接管

注意:

  1. 可能是由于开发板厂商的疏忽,E53标准中,规定17号脚(RTduino的9号脚D9)应该具备输出PWM波的功能,但是通过相关资料了解到,该引脚PC9并不具备PWM的功能,所以目前这个引脚只能做普通GPIO处理。
