Using 2 UARTS module at same time on msp432

Recommended Posts

yes, this approach has worked with my MSP432 Launchpad as well.

So example code running at 38400 baud for each would be:
   Serial.begin(38400); Serial.println("Serial UART");
   Serial1.begin(38400); Serial1.println("Serial1 UART");

On the MSP432 Launchpad:

   Serial RX/TX can be connected using the pins connected to the RXD<<, TXD>> jumpers (with the jumpers removed).
   Serial1 RX/TX can be connected using Pin3 (P3.2), Pin 4 (P3.3) per the pin map that comes with the MSP432.
