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 uart3 device. See example.

3.4 USB Virtual Serial

This board supports USB virtual serial. See example. You may enable it if is needed.
