I’m using the board, motordriver IIC, to control motor through I2C bus.The chip on the board is PCA9685.The board is originally a extension for arduino UNO, and I’m using STM32F446RE which also support arduino UNO expansion connector.The official g...

I also use the function read the register I write, (0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F, 0x10, 0x11), ans the value I read is the value I write in. Also, check the MotorDriver board and the motor, not the hardware issue.
