mclr reset 16f876a debug
hehe, thanks for the heads up on the site blueroom , I've just given it a check and it did take over a min to display, I think the host is working on something as my incoming email is also down
.
Back to the problem, nope definably not wired up backwards or odd, it was working away doing all the things a pic should do, then I power cycled the board and noticed the bench meter showing 200mA load (the max load for the little 7805) and low and behold, yet another 876 with all pins except MCLR, being almost shorts to GND.
I have a bag here of about 30 of the dam things all in the 12F or 16F range all get hot and dont seem to reset, I reckon I need to start putting a 100-150Ohm resistor after the 7805 regulator, incase some sort of a power spike is getting though, no idea how though, its got a whole row of 100u, 10u 1u 0.1u 100n 10n 1n 100pf 10pf 1pf filter caps.
I have just decided to do some whacky tests, the 876F is now in the freezer just on the off chance that a low temp might reset it, I don't hold out much hope though
.
Still if anyone has a sure fire way of getting a pic that's latched to reset and be usable again I'd be greatfull.
