Nokia 7110 LCD to Arduino Help + Freebies

[madeintaiwan]

Hello all,

My mother was raised catholic so I'm able to make confession by default, I think.
I bought a dozen Nokia 7110s off of you-know-where in an effort to a. save dough and
b. punish myself as there is no tutorial on how to connect an Arduino to a 7110 easily.
So my plan is to offer in exchange for helping to put together a tutorial, four of five of these LCD's gratis.

This is what I have found so far:

http://home.broadpark.no/~rrbakke/lcd.html

A link to someone who's got an 7110 connected to a ATMEGA163,
I have looked through the schematic he posted and have tried to match up as best as I can
the pin connections between that and the schematic for an Arduino Duemilanove
with an ATMEGA328. There are some discrepancies however, the pins he lists as "C1-C5" on the
163 I don't know what that corresponds to on the 328.



I have proposed connecting the LCD to the Arduino thusly, perhaps with the same resistor configuration as is stated above.



I have been through a few other links notably:

http://atomsofttech.info/index.php?option=com_content&view=article&id=46:nokia-7110-lib&catid=34:pic-micro&Itemid=53

http://serdisplib.sourceforge.net/ser/sed1565.html

http://forum.lcdinfo.com/viewtopic.php?t=632&highlight=7110

And gleaned some useful advice.

I have been able to get the led's working so far and one black square appear momentarily,
which may mean i have one broken one now.

I have pictures of my lcd with it's soldered ribbon cable to my small breadboard if need be.

I am lost when it comes to code for this too.

Sorry, did I mention that I was giving away 4 or 5 LCD's for helping me get this working?

Bad links.

Code: Select all

the pins he lists as "C1-C5" on the 163 I don't know what that corresponds to on the 328.

This would probably be "PC1 - PC5" (Port C bit1 - Port C bit 5). This corresponds to Arduino Analog pins 1-5 which can be implemented as digital pins 15-19. See http://arduino.cc/en/Reference/Board?from=Guide.Board. A better choice might be to use Port B on the 328.

Sorry, did I mention that I was giving away 4 or 5 LCD's for helping me get this working?

The gift would have to precede the help to be most effective.

This post is pretty old. I'm sure you must have solved your problem by now. If you have I would like to hear about it. In particular, if you found a connector for these.
If you haven't gotten it working I have a bit more info:

I found this link:
http://www.module.ro/nokia_7110.html

This fellow got the lcd working with a PIC. The code is in PIC assembly and is awful to read.
More importantly he includes the driver part number: SED1565 and you can easily look up the datasheet.
That along with his pinout should be enough to get it working.

Additionally, I have translated his PIC assembly to C but I haven't had a chance to test it yet. I'll post an update when I get it working.

While it is an oldy, it's still a goody. Would you like a couple of these LCDs to mess around with?

I'm still trying to get them operational and am glad for the info you sent, thanks.

[adafruit]

we will have a library + working code for nokia 96x48's (not 7110 but probably similar) in a few days if you're willing to chill over the weekend

[sobachatina]

Madeintaiwan-

I have three of the LCD's so I won't demand the shipping of you. I am planning on working on this over the weekend and I'll let you know how it goes for me.

If you find a good way to make a connector for them let me know. Soldering to those tiny pins is a pain and not very modular.
