The last firmware upgrade I made to the Picstart+ was to 3.0.32 Is this recent enough to properly and reliably programme the 18F452, or does 3.11 f/w make allowances/corrections for errata ? I'm asking because the only 17C44 I can get is > $50 from RS and I'd rather not upgrade if it's not absolutely necessary. I've not got the PICs yet so don't know what revision they are -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
