Hi all, We have a problem at work and it is killing us. For manufacturing reasons we upgraded the version of MPLab and firmware for the ProMateII so that we could program 16F872s. After we upgraded we found that the ISP programming of 16F873s now refuses to work. Everything proceeds as normal until the ProMate starts to blank the Flash memory, at this point it appears to freeze with the message "Blanking xxxx" (where the xxxx is another work I can't remember off the top of my head). If you pull off the programming header, it continues as normal, but fails the validation (as it should). Has anyone else come across this problem. robert. -- Robert Hodkinson, SF nut, Sound nut and a Render-head. reply email is bag.it@cableol.co.uk -- http://www.piclist.com hint: PICList Posts must start with ONE topic: "[PIC]:" PIC only "[EE]:" engineering "[OT]:" off topic "[AD]:" ad's
