Hi DaveThanks for the response1) I know there is the possibility of opening files, but I meant if there is a way of adding some include and having built in functions. Then I found some "GPIO Interfaces" txt file on the GPIO wiki. I saw there something to do with a header file and some c functions, or as it seems. Haven't gone over them yet, but will soon.
2) I may not have asked my question correctly. Regarding the UART I was really meaning to ask if the serial lines (which I now see are pins 9 and 10 I think) are the UART pins, and if they have to do with the serial console port (usb port for communication with the comp and getting a command line). Because if the are the same lines then it won't be possible to use UART and command line at the same time?
