Except for the last two, I think my existing setup 100% matches.... I have a bypass cap on Vdd/Vss right beside the chip. I know I have all of the Vdd/Vss pins "yanked" the right way. So far, there's been something like 1500 'F886es programmed with the existing setup. Since I obviously missed the need for the caps in the ProProg docs, I went back and scoured the documentation... and found it way at the bottom.. The proprog docs recommend 100pF for both, plus a 100 ohm resistor inline with the PGD pin... and no mention of PGM. I'm assuming 100pf will work and from the docs it doesn't sound like it's that big of an issue to be a bit larger than needed. I also don't have a problem with yanking down PGM - I've had LVP bite me in the rear too many times to not realize what that will help with. Do I also need the 100 ohm resistor? -forrest Olin Lathrop wrote: >> If you use a stand alone programming socket, you should: >> >> 1 - Make sure all Vss and AVss pins are connected to ground. >> >> 2 - Make sure all Vdd and AVdd pins are connected to the programmer >> Vdd output. >> >> 3 - Put a 100nF or so ceramic cap accross Vdd to Vss right at the >> socket. >> >> 4 - Put 47pF or so to ground on PGC and PGD right at the socket. >> > > I forgot > > 5 - Put a 10Kohm to 100Kohm pulldown on PGM, or even tie it to ground if > that pin doesn't collide with other uses on other packages. > > > ******************************************************************** > Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products > (978) 742-9014.
