Version: 6.1.2.00015
I am trying to make a very simple code but I don't know why the #29 error pops out. It's on the same line repeated, the ones in grey. The idea of the project is that using PuTTY terminal or any other terminal, I would be able to make one of the leds blink and control the brightness of the other led and when I write 'EF' in the terminal, the MSP430G2553 should return a status message.
