PIC programming algorithm - where is it to find?
Hello,
I was struggeling once again with programming problems and finally compared what my PICKit2 was doing "right" against my programmer(s) not succeeding.
So, I finally noticed that Vdd control is the key.
I use WINPIC and my (hopefully) last homemade programmer and added this control; since now, I have no problem at all.
I would like to understand how the programming process works exactly and I'm looking to find some information about it.
Unfortunately, I can find more than what is in the data-sheets (not enough for me... or to complicated).
Does anyone know where this information can be found please?
NB: in my understanding, an programming algorithm specifies i.e. the exact timing for a device ERASE sequence or for a device PROGRAM sequence.
