The only difference between a production programmer and a regular programmer is the production verifies the code on the PIC at two different voltage levels (max and min). It is an extra step which ought to be taken for large runs of chips (where a .1% error rate would be significant) but which is not needed for a small run (unless you like the extra assurance) -Adam Martin Hill wrote: > > What are the effects of programming voltage?
