To whom it might concern. I am using FPP ( http://people.man.ac.uk/~mbhstdj/fpp0943src.zip is the source ). According to the Thread being found at http://forum.microchip.com/tm.aspx?m=193136 I am currently looking for the 0x18 address respectively the BEGIN_PROGRAMMING variable. Where is it to be found in fpp or is DarioG wrong and the reason for the programmer not to program the 16F628A lies somewhere else ?
