Hi Mark Am I correct in assuming you have installed MPLAB 5.60? The p56000.hex file that is included with version 5.60 is the firmware to program the 18 series. The readme file says nothing about the 18F series only the 18C. It does say it conforms to the 18F0XX (DS411143B) spec, which is interesting because MC dropped the PIC18F0XX series. I ordered an ICD2 today so I will be using it. Maybe I should have purchased a Pro-Mate instead of the PICstart Dave > I don't know about the PS+, but the ProMate II definitely does support the > 18F parts, using the pm54060.zip files from Microchip's website. > Just downloaded the new pm firmware, programmed an 18F452, and it works > perfectly! > > Mark -- http://www.piclist.com#nomail Going offline?
