Rei Vilo 695 Posted January 25, 2020 Share Posted January 25, 2020 Which exact MSP430 MCU are you using? If it is the MSP430G2553, it only has one serial UART. You should consider other MSP430 with 2 UART ports instead. Additionally, the MSP430 runs at 3.3 V, not 5 V. You may need logic level converters to connect the serial device.
