Hi. I seem to get the following error whenever I try using "GPIOPinConfigure()" as shown below:
However I do NOT get the error whenever the function "GPIOPinConfigure()" is NOT used:
In essence, I want to be able to make a SSI connection with two TM4C123GH6PM launchpads in order to send temperature information (from one end) and print it onto a Kentec LCD screen (at the other end). The complete code of the sender is posted in the following:

I hope someone can help me address this error. Thank you.
