He told the ART2003 programmer works for PIC18F chips.
Can somebody please help me here regarding this programmer,
Can I use an external +5V power supply from a 9V source dropped to +5V with L7805?
I used it but won't worked. There may me mistake in wiring. There was no error in the 5V power supply. Like it was reversed or connected to other pins etc.It was not But it is definitely a shame to miswire such a simple schematic.
Before wiring that I used two 1.5V AA sized battery. And I put the 3V volt to the supply pins of PIC18F2550. It shouldn't worked as the PIC's minimum voltage rating is 4.5V.
Is there any chance of destruction of the PIC18F2550 through this operation?
I have only two PIC18F2550. Ohooo!!If I have destroyed it???
I'm building a ART2003 programmer on vero/perfboard. As I built it on my breadboard which is old and got some track breaking/rusting etc.
I'll test it tuesday.
