Re: 44 TQPF ZIF socket. Use ICSP | Piclist

A discussion group for the PICMicro microcontroller. Also called the Microchip PIC, this list is dedicated to the use and abuse of this fine, simple, microcontroller. Close to topic posts are welcome, ie. general electronics.

And you can't afford to have a small 6 pin header, or 6 in-line pads for programming via ICSP? ICSP also gives you the ability to debug once the chip is mounted, so you'll know if it's a misprogrammed device or a fabrication problem (shorts/opens etc.). It would also allow you change the bootloader if you need to (adding encryption for example). The overhead to support ICSP is minimal. A few resistors, and a diode for /MCLR isolation. Don't forget the pulldown R on LVP to ensure that you don't unintentionally end up in LVP mode. Robert If you don't have time to do it right, when will you have time to do it over?
