I am using Energia IDE V1.8.11E23 on Windows desktop to develop firmware for MSP430G2553 MCU.
My code is using the serial library of the Energia to output messages on the serial monitor for debugging purpose. I initially tested my code on MSP-EXP430G2 mLaunchpad Rev.1.5 with the MSP430G2553 MCU in 20-pin package (PW20) that comes with the Launchpad and it works fine to output debug messages on the serial monitor of the IDE.
However, using the same code on our own in-house designed board using the same processor but in 32-pin QFN package (RHB32), no message comes to the serial monitor display because Energia serial library is outputting data on the wrong pins for RX and TX as it has swapped RX and TX on P1.1 and P1.2 pins on this package.
