Piclisters who own / use a WARP-13 programmer are advised that there is a "mandatory**" firmware update for the 18F1220 and 18F1320. This firmware is available free of charge on my web site. There are versions for the 16F876 and a version for the 18F252 bootloader enabled firmware. Both versions require a 20MHz WARP-13 so you may need to do the 20MHz conversion as detailed on the web site. This firmware update was created after NEWFOUND ELECTRONICS received a sample from a WARP-13 user. This sample was from a previously untested batch and it would not erase correctly with the existing firmware. Happily, the problem was solved and the new firmware issued immediately. Regards, Jim Robertson NEWFOUND ELECTRONICS ** Mandatory means don't bother asking for tech assistance with any problems with the 18F1220 and 18F1320 until you have the likely fix-up installed. You are not being "forced" at gun point to do it. ;-) ______________________________ MPLAB compatible PIC programmers.
