I have the same problem, could they have done it to force you to buy a new programmer? I used a picstart+ until the 18F1220 came along, then I had to get an ICD2. ----- Original Message ----- From: "Jason Harper" To: Sent: Saturday, July 05, 2003 3:12 PM Subject: [PIC]: Inconsistent pinouts Does anybody have any idea why Microchip scrambled the locations of 8 of the I/O pins on the 18F1x20 chips, as compared to every 18-pin PIC previously made? This would appear to cause lots of unnecessary pain for anyone wanting to migrate an existing design to these chips.
