Note that the 4550 is a lot more common on demo boards than the 4455 as if designing a demo board you may as well put in the chip with more flash from the start rather than leaving some users trying to replace the chip. > or similar > big 18F PIC? Im planning to design one by my self, however if > someone already did one why not to share it. there are LOADS of demo boards out there for 40 pin pics in general, though most of them seem quite pricey due to having a lot of extras on them. Microchip have also released a new board for 44 pin pics as part of the pickit 2 debug express, i can't find a schematic of the board but the 44 pin 18F chips seem to be pin compatible with the chip thats in it (if you buy the board seperately they apparently give you one populated and two bare boards). --===============1462045950== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist --===============1462045950==--
