I am trying to control a number of brushless motor ESC (which look like servos) with a PCA9685 board for an underwater ROV. My language of choice is C. I am not asking for C code, but rather what is the I2C sequence of data you send to the PCA9865 in order to initialize and set to the PWM mode. I don't need a library of functions, just the data and registers that set the chip up.
Thanks,
David
