    I'm not sure how to do this with WinCE, but once everything is running you can connnect in CCS and check the corresponding GPIO IN_DATA registers to see if your input is correct from a hardware functionality level.

    If your current code has that many errors, it might be easier to just start from scratch with a new project. The code itself would be simple, only having to set up the PSC and PINMUX registers for the GPIO module. Then it's just register reads and writes to modify the contents of the GPIO registers. Check out the GPIO User Guide for more info.
