SED1520 lcd how?

Jos

Hello,
·
I have bought a DIP122-5NLED lcd display with two SED1520 controllers, the company told me it is HD44780 compatible. (specs at: www.lcd.elementy.pl/lcd/pdf/dip122-5.pdf )
But no I have the LCD, i think its not HD44780 compatible. There is nothing in the datasheets about HD44780 compatibility?
·
My question is, is there someone who has a pinout for a Basic and/or Javelin stamp.
I’m also looking for sample code to get this LCD working.
I prefer Javelin stamp examples, but examples in basic are of course also welcome.
·
Thanks.

would you happen to have the datasheet in english?

Meh. Nothing here, move along.

no, i'm sorry.
Half the doc. is in English, most of the German part is a reference to the SD1520 User manual.

I have intefaced the Javelin to a SED1200, and from a quick look at the datasheet of the SED1520, it looks other than a larger data bus the interface may work.

I think my code may be adaptable but I don't have it with me right now (it also contains my pinouts). I will look into this more later today (or this weekend) when I get home.

I speak German, if you need help.
BTW Translators don't work.

Since the Manual is in English though, I don't see too many Problems...

You can test if your display is 44870 compatible by looking at this thread.

This person made a project that uses a 44870 and they include hookup descriptions, and code. (just use the code you need to get the display to work)

i tried with to get the lcd working with the 44780 pinout and code.
But without success [noparse]:([/noparse]

· If anybody wants it, here's a link to an all-in-English PDF for the SED1520 -- http://www.eio.com/sed1520.pdf
· I'd U/L the PDF, but this way takes up less room on the Forum.
· I think that it has much in common with the 44780.·Looks like·one difference is that isn't 4-bit/8-bit selectable (only 8-bit.)

I found my code for the SED1200, but haven't had a chance to start editing it. (any edits would just be a stab in the dark based off the data sheet because I don't have a SED1520 based LCD)

Keep in mind that this code was a quick test, I recovered the LCD from an old printer and I just wanted to see if i could interface with it. I may try and work on fixing the code to match the SED1520 but I'm not sure when I will have time...

Maybe someone can get me back on track, at the moment I’m still pulling my hairs out.
I found some sed1520 code, I translated it to Java to run on the Javelinstamp.
But without results [noparse]:([/noparse] I just want one pixel to light up! At that point I can handle the rest.
