myRIO UART

[Zillion]

Is the Motor Mind B motor controller compatible with the UART on myRIO? I can't seem to get it to respond to commands. I may not have my VI correct, or I may not be understanding the controller correct.

Hey,

If you have the UART ports configured correctly, it looks like you should be able to communicate with your device.  Just make sure you have the correct baud rate, and one stop bit. For testing purposes, I would try just sending and receiving commands once, and not repeatedly in a loop.

One thing worth mentioning is that the UART port is meant to be connected to a serial transceiver and not directly to a serial device as the transceiver has the RS-232 physical layer necessary for voltage-level translation.
