Hi Up until now I've been using assembly language for programming 16F84s and I'm now moving to using C for the hitech PICC Lite compiler suite that's distributed with MPLab IDE 7.62. Do you know of any web sites that have circuit construction and programming exercises that'll help with programming in hitech C?
