Hi, I'm running Energia on Windows 7 x64.
My Launch Pad model is the MSP-EXP430F5529LP (25Hz)
My board's green LED will light up when connecting to the computer, the red LED will flash while compiling and all onboard LEDs and buttons function when programed. However, whenever I try to program output pins and connect the output in question to ground, I get no current out. I have plenty of experience with Arduino and all programs I write for the Launch Pad work for Arduino. The GND, 5V and 3.3V pins on the LaunchPad all work fine. I have also used a number of sample programs, all to no avail.
Here is a schematic sheet for my model. http://energia.nu/img/LaunchPadMSP430F5529.jpg
Here is a quick program that I have written to demonstrate one way that I have been testing it.
