Hi folks
I have built a division controller using a board copied from a post (#346) by Lucas. To my dismay it did not work. I checked the board against V2.0 of the circuit diagram and it seems fine.
I don’t have a display at all. I used a 60 ohm resistor to supply pin 15 of the LCD.
I checked the points listed in the build manual and the only problem seems to be that of configuration bits not being the same.

My display obtained from RS is a Displaytech 204a which doesn’t claim to be HD44780
Compatible, the connections appear to be the same though?

I used a Picstart Plus to Program the pic with version 2.12 I noticed that the configuration bits were not the same as Steve posted in post #23.

Please help it would be simple if the display is incompatible or my attempt at programming the chip is wrong, I haven’t done this for years and am very rusty with the picstart!
