has anyone worked with MSC-C242DGLY-1W-E which appears to be an 8 bit interface (can't do 4 bit) parallel 2x25 LCD with a back light?

Those are OEM Seiko L405200J000 / L405200P000 and the markings on the PCB show MSC-C242DGLY-1W-E

It seems to be made by many different OEMs as listed http://s193925491.onlinehome.us/pix/MSC-C242DGLY-1W-E.pdf

 

The (annoyingly huge) datasheet you provided the link to shows standard 14/16pin char LCD using the KS0066 driver.

Pretty much any code you will get from google to drive a 1x16 or 2x16 etc LCD will work fine.

 

I have not worked with this particular LCD display but it appears to be HD44780 chip based which means that you should be able to find some example programs on the Web.

The data sheet to which have provided a link contains a flowchart near the end of the document provides all of the programming information that you need.

Maybe you can take a stab at programming and then post here if you encounter a problem.

Thanks everyone, I will give it a try and post some results. However I am now confused about the meaning of this spec sheet.

Can the logic be running at 3.3v and the LCD at 5v? The power inputs are separated. VDD is logic supply and VO is LCD supply (and yet another pair for the back light but that's outside the scope of my question).

Thanks
