Interfacing with a SED1278F controller

Hi all,

Has anyone had any experience interfacing to a display using the SED1278F controller? Can't get anything to display using the standard LCD examples, and yes, I'm a total nube at this :smiley:

Any help, gratefully received.

Regards

EW

We have all the information we need to help you except for the following:
(1) A link to the controller data sheet.
(2) A copy of the actual code that you are using.
(3) A photograph clearly showing the actual connections between your Arduino and your LCD module.
(4) A description and/or a photograph of the results that you are getting.

My Apologies.

Datasheet: http://pdf.chinaicmart.com/SED/SED1181DLA.pdf

The code is the standard Arduino examples that come with the software.

I'm getting no results on the display. The display board I'm using comes with no datasheet or pin-outs, so some of that is guess work, although I think I've got them all correct. The board is definitely powered, and the pins seem to be the same as an HD44780, although obviously I could be wrong there as well!

Just wondering if anyone had any previous knowledge of this chip with an Arduino.

That looks like it is compatible with the 'standard' Hitachi HD44780 controller.

Do you mean the 'Hello World' example that comes with the Arduino software? If so why not tell us that instead of making us guess?

I'm getting no results on the display.

If the display is completely blank then you haven't got some combination of the power/contrast/backlight set up correctly.

... although I think I've got them all correct

I've heard that before. How do you expect us to correct any possible mistakes if you won't tell us how you have connected things?

... although obviously I could be wrong there as well!

That's quite possible.

There are several of us that have helped dozens of people although possibly not with this particular controller. Since they are all basically the same the particular controller in use shouldn't make any difference. We can't help you unless we know exactly what you have done so far.

Have you tried the tutorial at Arduino Tutorial - connecting a parallel LCD ?

Older Post, but same Problem (solved):

I got a EPSON EA-D160015AR display from my died laser printer.
I found the data sheet at http://www.datasheets360.com/pdf/550536148969697732 and it's absolutely pin compatible to the "standard" HD44780 controller.
A I2 board with the "LiquidCristal" "i2c_helloworld" sample works without any changes.

Hope this will help.
