I found another thread on the forums referring to code examples for a controller that uses the same type of Capacitive I/O sensing, the FR4133. There are actual code examples for that controller (labelled PINOSC in MSP430 Ware). The only necessary change was to change the used timer since the FR6989 has no connection between the Capacitive Touch I/O peripheral and Timer A0. I changed the timer to A2 and everything worked. The example in the attached file works with the launchpad. Just connect a wire of some kind to pin 1.4 and the LED should light up on wire touch. (Please visit the site to view this file)
