Actually 0x0C for F84 ;-) -- Best regards Tony ICmicro's http://www.picnpoke.com spam_OUTsalesTakeThisOuTpicnpoke.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

But I DO have an excuse. I mean, I work for a company that makes 8051-based microcontrollers; I can't be expected to know all these little details about PICs. -Andy === Andrew Warren --- aiwKILLspamcypress.com === Cypress Semiconductor Corporation === Interface Products Division, S.D. === === The opinions expressed above do === not necessarily represent those of === Cypress Semiconductor Corporation. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

It's a bit academic in any case 'cause it's still no go even with 0x0C. Triple checked the circuit - AOK. I dunno - maybe some things just aren't _meant_ to be done! I'll keep fiddling with it, just in case, and I'll leave the file at :- http://www.netstra.com.au/~elek/smartlcd/smart01.html Guess the next move will be to get rid of the KPD & interrupt and just duplicate the working 16C57's test message only and see if that works. - Ian -- http://www.piclist.com hint: The PICList is archived three different ways.
