Hello,
I want to be able to program the PIC on my POV toy, without having to take it off and put it into the programmer. This way, I can solder the chip and stuff to the PC board and when I want to change messages, just simple reprogram using an ICSP cable / header.
The thing is, when using the ICSP-- does one need to disconnect other components such as LEDs or resonators which are connected to the chip at the same time? Or can they be connected to the microcontroller pins while I use the ICSP?
I am thinking of using 16F628A, or 16F684-- if that makes any difference.
Thanks,
Omar
