Hello
I'm need to control a bunch of servo-motors by a FPGA board (Altera cyclone IV core). I'm using a PCA9685 as the driver of the motors. I would be greatly tanksful if you could give me some hint or if it's possible a Verilog based example for running the motor driver.
So far I assigned a pwm output from the fpga pin to SCL pin on PCA board, beside the vcc and the ground, I also wired one of the switches as for 0 or 1 to SDA pin assuming that the 0 would chose the servo 1th and the 1 would be choosing the servo number 1. nothing happens so far :)).
Thanks in advance.

Hi, thanks for reply however my concern is about controlling the PCA9685 as the i2c to controll the servos.... not direct control.
