hi
i have built a circuit which have pic16f877a tqfp and few 3v sensors. i forgot to program bootloader in the chip and have soldered it. now how can i program it? can i use jdm programmer to program it? i fear that using jdm may damage 3v sensors since pic+sensors have common power and ground lines. Is there a way i can program it without damaging the sensors? removing the pic is the only option?
thanks in advance
