Hi. Before I dive to deap into the programming spec, maybe someone know already if the programming of the 16F883/884/886/887 are compatible with som older modells ? Or, to be more specific, should one expect the Wisp628 (with Robs patched firmware) to be able to program these devices ? They are not listed anyway... The 16F88x line seems to be a nice "upgrade" from the 16F87xA line (which today lacks some of the newer features...).
