> Why do you recommend me to not mess with pre-18F chips? The 18F chips are more capable and easier to program. They costs slightly more than the similar 16F chip in the same package in small quantities (cheaper in large quantities), but that doesn't matter for hobby use if you are only going to by 5 of them. The 18F chips are also Microchip's "latest" technology, so this is where the new development is. I doubt you're ever going to see a PIC16 with CAN or full speed USB, for example. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
