Finally getting somewhere!
Hi guys,
Well at last I have got my programmer working! Win Pic seems to do the trick, and programs my 628A with no problem.
Thanks Picasm.
Now the bad news, thanks to Eric's code I was able to see if there was any output to the LCD and sadly there isn't, so I have a problem somewhere.
I have even breadboarded the PIC to an LCD and the same result - no characters - just the blocks!
Now at least I have narrowed down the problem a bit, it surely must be something to do with the LCD connections, so I am going back to the datasheets for them to see if there is anything wrong - my god these straws are hard to clutch at hehehe.
Anyway thankyou to you all who have participated so far and allowed me to at least keep my sanity, if not my hair! hehehehe
I will keep updating the thread as I progress in case maybe someone in the future will get the same problem as this or maybe the same LCD screens.
Just a thought but could the fact that the design calls for a 2 x 16 LCD and mine are 2 x 20 be causing my grief, though I have also tried a 1 x 8 LCD though neither came with a datasheet, the connections seem fairly standard on LCDs or I hope so after all this trouble!
Thanks again folks, I don't know what I'de do without the help!
