> So the pickit4 has pay-per-use features? I need to go see what those are= , I haven't seen any details of what the PTU features are, but don't forget t= he Real-Ice has had such features for a long time. They are pay once featur= es, and are pretty low cost for the Real Ice ones. I suspect that as the Pi= ckit 4 gets established then these features will become available. I'm gues= sing they may be similar ones to those available for the Real Ice. --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
