Hi,

Can we have more information about what you have and how you're trying to
control it? Does it have all the proper supply voltages to the display?

Is it one of the LCD displays with the HD44780 controller chip? If not, do
you have the data sheet of the controller chip the display uses? I have
the full data sheet on the HD44780, which is hard to find.

What programming language are you using? C? Assembler?

You might have to post your code here for us to help you.

hi;

I connected AVR to this kind of LCD many times, there
is some sort of difficulties to use it. maybe some
timings at startup makes the LCD to malfunction.

if you need some sort of sample codes, google for
AvrLib or something in forums and use in your code.

I see there is some data in thr group's files about programming LCD's.
There is a folder called "LCD" with some programs in it, as well as the
Optrex "Dmcman_full.pdf".

I just uploaded into the group files the data sheet on the HD44780
controller to complement these files.
