hi all. please pardon a newbie question that i'm sure has been asked a thousand times...i teach a basic electronics class and the kids are big into remote control. we have a class set of picbasic pro compilers/programmers so we use PICs often. i can easily configure a PICF627 to PWM 38 hz and have it be picked up by another PIC across the room using the plain ol' three pin sharp receiver...basic on/off stuff. what i need to know is how to carry more than one code on the 38hz PWM and have it decoded by another PIC. i know that rentron has a simple chip that has 4 channel remote control but this won't work for a classroom...the kids can afford a couple of bucks for a PIC but not the cost of the chips from rentron. i need a way of understanding the method so that the kids will understand (and a way that i will...for that matter) is there a simple bit of picbasic pro code i can plug in like "serout and serin" or something? am i just being confusing? HELP!!
