[oopic] Re: NC2004A LCD Screen with Modtronix LCD2S daughter board

Cheers,

I am looking at this now. I am trying to work out what Mode it should
be using.

An example of the commands it is looking for to get the status is:

SaaaaaaadAccccccccASaaaaaaadAbbbbbbbbP

S= start
a= address bit (7 bits + direction)
d= read or write bit
A= acknowledgement from slave
c= command bit (8 bits)
b= First byte of data (8 bits)
P= stop

If the address is 0x50 then it would look like:

S01010000 A 11010000 A S01010001 A {Recieve first byte of data}

I hope it makes sense, Looking at it I am assuming it is cv7Bit.

Or would I need to do some custom controlling to get this working?

Thanks for any help,

Jas
