I conect ICSP directly to pins. And from konektor, other part of circuit connect via 2K resistor. If you use pin as inputs, then other hardver driving state of pin. So not to have colision with...
I wouldn't do that. Your safest bet would be to have a jumper you can remove to isolate the output of the HC14 from the PGC/PGD pin while you're programming.
Not sure how I would have and looking at that register even any value 0's or 1's, it would still work??
Considering the application doesn't require any precise timing, should I provide a...
sounds like you have over written the osccal/ value stored at the top of memory for 12f508.
Most programmers will not reprog that chip when the value is missing.
The old pickit2 can reset a value...
its very easy to do.
on a pic curiosity board the pins are just there begging you to use them. you can kinda forget the programmer is on board
when there is no need to plug and unplug it at all....
To be clear, I will NOT have the circuit powered when I'm programming. The PCB must be removed from the main board in order to be programmed (I use the same connector for operation and for...
Re: Reusing PGC & PGD pins
You have to be careful when using the pin as an input.
tumbleweed Today, 14:44While a series R can help isolate the pin from the ICSP programmer, if the external circuit is driving the pin high then this can change the...
