Post by thread:[PICLIST] promate II and 16F873 ISP problems.

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 spam_OUTbag.itTakeThisOuTcableol.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

We have had our problems with ISP, but not with a Promate II. We have been doing F873, F876 ISP with a PicStart Plus. The problem we had was related to improper isolation of the data and clock signals. The firmware of the PicStart would plow through the whole thing and fail on Verification. Also, occasionally, a PIC would get into a funk and could no longer be programmed ISP. (We desoldered them...) I'm not sure this helps, but I am feeling rather convivial today.
