hello, I don't have a book with me at the moment, and I'm not sure if this command is checking for a one or a zero.... BTFSS control, pin statment is this going to skip the next instruction if the pin is set or cleared? thanks S - means set correct, meaning 1?? if pin = 1 then skip next instruction --correct -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
