Hi people I have a pic 16c84-10/p that has bourne the brunt of my efforts at learning the pic assembly language and it failed at what I estimate as 200 or so times (being reprogrammed).The symptoms were an absolute refusal to be reprogrammed with no previous errors during programming. Or rather I should say no more than the usual ocasional glitch.I have a few others so my question is was 200 times to much.My program is nearly complete and it writes accumulated values to eeprom as well as user changes with a million writes lifetime I estimated approximately 15 years before eeprom failure and then only the least significant digit would be affected. Lead me. Tony M.
