15 years agoA transmit UART is really just a parallel to serial converter that adds the proper start and stop bits to the signal. If you want to know if you can write behavioral VHDL (not soft processor based code) that communicates with a serial device, then the answer is yes.
Is your stepper motor something you command with serial commands? Can you control your stepper motor through hyperterminal or minicom? If so it is not very hard to transmit bytes using VHDL but you might have to convert between ASCII and binary. Receiving bytes is a little bit harder, you have to oversample the incoming data stream to detect and frame the bits but not too hard.
