Hello everyone again,
I am having some probably really silly problems with my lcd module on my breadboard (http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=280745794895) i have it wired exactly to the diagram in the syntax manual and i have checked and re checked many many times, i have looked for a datasheet for it with the number on the back (YBA2004A) and i use the first one when you google YBA2004A, but it didnt really help me much.
I used the example code but with a little modification on the pin outs to fit my 28x..
Thanks heaps
Grazza

edit: there are also a lot of missing components on the back, well just gold pads with resistor and capacitor numbers next to them

Sorry, probably need lots more information for anyone to help out. My google of the part number did not show up anything useful. so link is always good.

In cases like this: pictures help a lot, also simple example of code that is not working is very important.

Also what is working or not working with it?

Kurt

Does the LCD do anything when you run your code, anything at all? Also please post your code.
