I've done USB on JAL on the=20 PIC18F4550 and powered it + Graphics LCD from the USB. But there may be better choice. the JALV2 USB libraries seem easy to use=20 on 18Fxxxx and 18FxxJxx that has USB built in. So no-one have a preference on PIC 18F that has built in USB? What could you add to make it a more useful gift but still cheap enough=20 to give away? --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
