Hi again guys. Thanks for the replies so far. I now find myself facing another dilemma: I now have to learn C as in VERY quick due to balls-up in my study pre-requisites. The new lecturer (old one's in Germany now) wants to interface the PIC with the lab PC's and display something on the monitors. Written in C of course :-(| Very nice idea, BUT we will be using RS232. Now - do I need a library for the PIC or the PC? I think the PIC since the compiler will use the library for the PIC.
