Hello,
I am working on a robot by using the sabertooth 2x5 motor driver and also an FPGA spartan3. I am having trouble how to generate a signal output from the fpga to go into the motor driver to be able to control the motors. Has anyone done this before? I will be using the RS-232 serial port. And I am using Xilinx to pogram the FPGA.
Thanks.
Have you programmed the FPGA with serial port code to give it a serial port? You have to have serial ports in the FPGA before you can hope to have it communicate with the Sabertooth 2x5. You can find a lot of free FPGA IPs at OpenCores and FreeCores.

Yes the FPGA has a RS-232 serial port and I have already used it as a reciever now, so I am making some progress.
