Those are the firmware files for the EasyProg. This is clearly written in the doc file for the easyprog, "easyprog.txt". > There is no explicit manual on burning the chip for > this module. So what ? There is nothing particular about that. You use the EasyProg to burn a *new* version of the firmware, and you use some *other* programmer to burn the *first* version (since you obviously do not have a working EasyProg in that case...) Burning the firmware is just as buning any other hex file.
