But it's strange Laurent mentioned it... I think Laurent should downgrade and verify using a more minimal implementation -- use a basic assembly language INTOSC blinker. If that can be checked, then we can tick off a few items as checked. I've tried a lot of one-LED blinking without decoupling caps, they all work. If he's using a crystal, the circuit ought to be clean of flux residues, even no-clean types. I've found in the past that wet-weather tropical humidity plus unclean traces is enough to very easily stop 32kHz crystals, and even one 4MHz crystal. The same circuits worked a little later on a sunny day... > On Thu, Jun 9, 2011 at 5:46 PM, Dave McGuire wrote: > > On 6/9/11 11:17 AM, Laurent FAILLIE wrote: > > I think my powersupply is too noisy and the xtal doesn't > stabilize > > ... so the PIC doesn't start.
