I have been looking for several hours and I hate to admit I don't know where else to look. All I am trying to do is read an input from PTB9 and send an output to PTE5. I have the components installed in my program and there's a fair chance they are installed correctly.
I have been unable to find out how to access them from a C program. I expect I can do it by writing to and reading from the memory locations, but that is not a good idea in general. So, would anyone care to enlighten me on this obviously simple technique that I am failing to locate?
Thank you very much.
