Request for a verilog code to connect PCA9685 to Altera Cyclone IV FPGA based development board

[first_rain]

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 Artin,

I found a open source reference related to servo controller that might be heloful. You can refer to link below for details.

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