Hopefully I'll get this figured out but want to ask also because I need to get this done today.
Haven't messed with PICs in a long time and never had a problem -- using a 12F675 and getiing "programming error at 0000".
My EPIC programmer (I know, an antique) sees the chip fine, device is blank etc).
One post I ran into is this --
These seems to have been discussed on here before, but I can't seem to figure out my problem.
I've got a 12F675 setup and it will program a couple of times and now it doesn't program and won't erase. I'm using MELabs Serial Programmer and trying to set it up so that MCLR is an input and the internal osc is used.
I also am using gpio3 as an input and using intosc (will try to change gpio3 to another pin and see if that works).
Anyway -- anyone have experience with this?
And on my old chips, I always had mclr enabled and held high. Is this still a good practice? Never used the newer chips like the 12F675.
Didn't know gpio3 was also the mclr or wouldn't have used it in the first place but my pcb is already done.
