LAUNCHXL-F2800137: UART Transmit and Receive

Part Number: LAUNCHXL-F2800137
Other Parts Discussed in Thread: C2000WARE

Hello all,

I wanted to establish a UART transmit and receive communication between two LAUNCHXL-F2800137 dev boards. It means one LAUNCHXL-F2800137 board will act as a UART transmitting node and another LAUNCHXL-F2800137 board will act as a receiving node.

They will be physically connected with the SCI_RX & SCI_TX GPIO pins of one board to SCI_TX & SCI_RX GPIO pins of another board through jumper wires. As the transmitting node will be sending some stream of bytes and the receiving node will be storing the received data and printing the same on the terminal.

Please guide me through the successful UART (TX-RX) communication between the two nodes.

Regards

Yash

    Hi Yash,

    For UART communication using the LAUNCHXL-F2800137, I would recommend using the SCI modules on each LAUNCHXL-F2800137 device. The SCI module uses a UART protocol and has both TX and RX lines. We have some SCI examples in the C2000ware software package you can adapt for use on each device. They can be found in [C2000ware install]/driverlib/f280013x/examples/sci. Another useful resource is the SCI section of the F280013x TRM linked here. Let me know if you have any other questions.

    Best Regards,

    Delaney
