I am using a ATmega328P uC with a TLC5940 (Used in a PWM Mode w/ pullups).
I use a MAX485 chip to receive the serial commands. It works well with most motor controllers and all servos.
The one motor controller it doesn't work is the Vector Motor Controllers. I can't figure out why they don't like the signal(They think that the signal isn't there). Attached is the schematic of the system. Any suggestions would be great!
Thanks,
Rick
