Appreciated PicListers, After some months working with 16F84s I have decided to go one step ahead and start with 16F877s (I need more I/O lines !). Before burning my first 16F877 I would like to know whether there is anything that I should take into account about 16F877s (some particularity, oddity, brain breaking caprice of the IC designer, etc...). If I take a 16F84 program and burn it into a 16F877, will it work ? (that is, init sequences of the several I/O devices not in 16F84 are mandatory to make a 16F877 behave as a basic 16F84 ?)
