Hi people! Long time since I've posted... I wanted to ask if someone had good/bad experiences on making the 16F88 chips program themselves via a small bootloader subroutine and rs232... I was going to use rs232 anyway in my circuit for configuration and offloading of statistical sensor-data, but then I found the chip can self-program! By telling chip to reprogram memory, upgrading software would be possible after I mold the circuit into epoxy too! (This circuit has to be waterproof and very sturdy so molding it is a good and fast way to achieve that.) Pipedream or possible ? Share your experiences please? Any dogs burried in this approach ? Anything I need to consider? Kyrre -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
