> How do you plan to make the power cycle? cutting VDD for the PIC to Reset= ? I have no plan. The programmers that I know will cut Vdd and/or short=20 Vdd to ground. But this will result in the battery kicking in, thus=20 preventing the PIC from being power-cycled. Maybe I should reconsider the whole idea. A low-voltage-only PIC or an=20 LPC1114 might be a better idea than trying to combine a 5V PIC with=20 battery and ICSP. --=20 Wouter van Ooijen -- ------------------------------------------- Van Ooijen Technische Informatica: www.voti.nl consultancy, development, PICmicro products docent Hogeschool van Utrecht: www.voti.nl/hvu C++ on uC blog: http://www.voti.nl/erblog --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
