I am trying to see if I can relieve the overloaded Interrupt by using the serial port of the 16f628 in a NON INTERRUPT basis. Has anyone done this or found it to be not possible? Any sample ideas would be appreciated Contact with others working with the 16F628 will also be appreciated Larry Kayser PS Thanks and the best to everyone for the Holiday Season -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
