Let's Make Robots!



Has anyone tried using These LCDs with an arduino? I'm not sure whether they're HDD44780 compatible or not, and I can't seem to find much of a datasheet.

Thanks in advance.

Thanks for all the replies. Am I right in thinking, then, that the basic library should work, but I might need to adjust the timing a bit? If so, how hard it it to sort?

Also, how hard would it be to adjust in python? I've found this tutorial on using the hd447 with a RasPi, so presumably sorting it to work with these LCD would be pretty similar.

that can help


Or may be that



I also have a DMC40267-NY-SLY-E-AZ, if somebody have a datasheet, I cannot found on google ?

There is one on this page that is probably close enough



The datasheet says it uses an st7066u controller chip.  Googling that says it is hd44780 compatible, but also brings up some possible compatability issues.  Give it a go.The worse thing can happen is it doesn't work quite right.

Google the part number PC1602ARU-HWB-G-Q and you will get the datasheet of the Farnell website...

I've had a look through the datasheet, but I'm not sure how to adress it. I know that the arduino works with the HDD44780-type driver, and there's a library around to use it, but I'm not sure whether it'll work with these. I think I can figure out how the characters are adressed, but I would rather use an existing library at the moment, as I'm not exactly experienced with arduino.

I think you forgot to post the link to the LCD...

Sorry. Sorted it now.
