We are looking for an experienced Embedded Systems Engineers who has working experience with PIC18s, preferably PIC18F4550. We are developing a product based on PIC18F4550 and can't get interrupts to work properly. More specifically, we have a switch connected on port RB0 and an LED connected on RA0. All we need is that when the user presses the button, the LED is illuminated. We have written basic code for this purpose but it does not work as required. We need someone to look at our interrupt code (via team viewer) and make fixes to get this working as needed. An experienced person could get this working in a few minutes we presume.
