he he. I suppose your right. The one in question is a gps unit with built in compass. It uses Asynchronous TTL level at 4800bps, 8 data bits, no parity, 1 stop bit, non inverted. All in a single pin parked SIO. It has an adapter that converts regular serial, to this single pin async ttl serial. I can communicate with this no problem without the adapter with the CRIOs serial port. But then came the idea to use 2 of them. One on the turret and one on the main frame of the robot. Our last thought was to use the cypress board to read the heading and pass it in through the DIO as a binary number.
