Making the mock-up work alone, separated from its debugging environment

I do not see anything wrong with the hardware, but your code just runs to END and ends.

But, if all works well when connected to the PICKIT2 and I will assume using the PICKIT2 to power the circuit... What are you using for a power supply?

Dave,

The power supply is a DC/DC converter (MAX1724) embedded on the board which converts the 1.5 V from an AA battery to 5.0 V

And how many amps does that give you?

[MikeBZH]

I measured 100 mA on the 1.5V
This should give about 40 mA under 5V

Bet that is not enough. Try a better power supply and see what happens.

MikeBZH, I have designed a 900 Mhz, wireless interface for my wifes DDR pads that interface with a Gamecube or PS2.. I use the same (MAX1724) which powers the receiver and 2 18F2620's as well as 3 leds... I dont believe the upconvertor is the problem...

Hi !

I finally got the answer from the Microchip forum :
No gremlins in the circuit nor powr supply issues.

Simply, with MPLAB, I had to select the PicKit2 as a Programmer instead as a Debugger.

And now, it works !
