The Arduino Compatible for CH32V307V-R1

English | 中文

1 RTduino - Arduino Ecosystem Compatibility Layer for RT-Thread

CH32V307V-R1 board has support RTduino. Users can use Arduino APIs, third party libraries and programming method to program on the board.

1.1 How to Enable RTduino

This board complies with Arduino UNO pins layout. For more details, Please go to the RTduino repository.

Notice:

  1. Don't use a same hardware timer to drive PWM (analogRead) and servos at same time, because hardware timers can only generate a same frequency for 4 PWM channels. Otherwise, it could cause a failure when drive servos.

3 Communication

3.1 I2C Bus

I2C bus is SCL/D15 and SDA/D14 pins. Users can directly include the #include <Wire.h>, which is the Arduino official I2C header file, to use the I2C bus.

3.2 SPI Bus

This board doesn't support Arduino SPI header file and functions.

3.3 Serial

This board supports to use Serial. method to operate uart1 device. See example.
