Definately don't want to put 9v to the board directly. The board should have DC to DC converter to raise 5 volts to the 7v required to run the backlight. (I believe it'll work with 3.3 volts as well)

But any higher than that you're risking it. You can use a voltage divider to bring it down to 5v if you NEED to use the 9v. (Keep in mind, 9v batteries don't have very much power.. you'll have a dead battery fairly quick, especially with an LCD connected, you'd be better off to use multiple AA batteries, or another supply:D)

Well.. I've been using the LCD for a base station for my RF kits, just to use it for debugging. I went through the whole PDF that explains how to interface it in like, 140 pages.. I tried to steal the Circle code from the example, but it's not working as expected. When I try draw the circle, it just draws a line at the top of the LCD, *shrug*.

Also on the LCD controller, it shows that there is some EEPROM you can use, how exciting. But anyways, best of luck!

Thanks for the tips!  I used a 7805l and powered the screen and arduino fine for a while until the 9v ran out.

I made some optimizations and posted the updated code here: http://www.beigerecords.com/joe/?p=378

Has anyone gotten this thing into 8-bit color mode with the sparkfun breakout board?  I tried a handful of things in setup and have only seen 12-bit mode.

Hi again.
Now I found my Nokia LCD one more time, connected it, and tried the code again, but I'm still experiencing the same problems as blip (look at his image)
Does anyone know how to fix that, or at least why it is happening?

If it weighed more and wasn't wired to my computer I would have thrown it across the room.

Loaded up cougar's mandelbrott demo and got the blue screen of nothingness.

Loaded up the gravitech code with phokur's changes and got a sorta kinda good result.  There seem to be bleeding pixels in the middle of the blocks.

with the code below, trying to us the 16bit color interface, I get something more than nothing, but less useful.  With a line in the middle that I don't understand at all.

When I use Phokur's updates, well, nothing works the same as before.. and not in a good way! lol pixels galore..

I've been trying to implement how to use a BMP.. but that's proving to be a bigger pain in the ass than I normally expected. :P

Hello everyone,

I got the SparkFun Nokia knock-off break out board just like Phokur and I am having the same problems with weird colors and text. After I applied his mods (especially for the text size) I got some results, meaning the text is legible but the colors are all messed up. I am using the library you guys made and I am making the tweaks you guys recommend to see what's working. I have a few questions:

- why aren't we using the hardware SPI?
- why aren't we using the 12 bit color scheme instead of the 8 bit one?
- is there a possibility to flip the image 90 degrees?

I am using diodes and pull-up resistors for voltage converting, unfortunately I did not had shotky diodes handy, so there might be a timing problem for the communication.

Another weird thing, the LCD seems like looping through the DATCTL settings because I got solid color bars (black yellow blue cyan) then garbled color bars (black magenta cyan white) and the text changes colors too. When is garbled, each color bar has vertical lines, one line color, one line black and they alternate from one color to the other, that means if for the first color the black lines (columns) are even, for the second color the black lines are odd. The text appears with vertical lines too, like the LCD has less resolution or something like that. Sometimes the text has red lines above and below each text line. All these are looping over about 15 cycles or so.

At this time I wish I had bought the Nuelectronics Color Arduino Shield instead of the Sparkfun's board or the one CaptainObvious has.

Ro-Bot-X

Anything new on this? Is anyone making some progress? Should I toss out this color LCD and buy another one that works?

Thanks!

I gave up on the color settings, so I can actually use the thing on my robot. I finally succeeded writing the code for a scan and display map module. I used the Ping sensor, which makes the objects be wider than they are, but is crazy fast. I wish same speed could be achieved with Sharp sensors. I can post up the code if someone needs it.

Here is a video:
http://www.youtube.com/watch?v=uDAzn4w4WUU

Anyway, looking for ways to properly set up the display, I found this amazing code written in C++ for Mega8, 16, 32... 644. It does everything, but it's a bit over my head to understand it. I would like to port it to Arduino as a library. Can anyone help with this?

Hi, I'm using this Nokia 6610 LCD (Green PCB -> Epson) over an Olimex board (http://www.olimex.com/dev/mod-nokia6610.html) equipped with a DC-DC converter to have the correct 7V to power the backlight.

I've wired this board to my Arduino Duemilanove working with an AtMega328 and the 0017 version of the IDE.

I'm experiencing the same Blip's and other users problems, that consists in wrong/mismatch visualization of the data sent over the SPI bus.

I'm checking the data over the bus by a logis state analyzer and it seems the data was correct, but I'm still analyzing...

I also checked the new Epson controller datasheet to be sure the command sent to the lcd was correct, but none is working.

Somebody have some news about to control this device?

Today I'll try to compile my simple source code with another IDE version (0011>)... grrr...

Hi, finally I was able to correctly drive this LCD. The issues was the following:

1. new Epson LCD are equipped with a new Epson clone controller that doesn't supports 8 bit color driving
2. it's necessary to set the P3 parameter of the DATCTL command to the value 4 instead of 2.
3. new datasheet's revision of the Epson controller (S1D15G10) that can be found via Google search, now contains the info of the point 2 that isn't contained in the old revision (S1D15G00).

I'm astounded by the work done on this board.

I'm pretty new to Arduino's, and I'm chugging through my first real project (after playing with a bunch of tutorials).

I'm trying to print numerical values generated by the Arduino (Longs):

strcpy(text,"Speed");
nokiaLcd.lcd_draw_text(MAGENTA, BLACK, 7, 90, text);
strcpy(text,"0");  // <--------  I want to replace this "0" with a Long variable
nokiaLcd.lcd_draw_text(CYAN, BLACK, 40, 90, text);

I've tried various methods of swapping out the "0" with the variable velocity.  I keep getting:
error: invalid conversion from 'long int' to 'const char*'
when I replace the line above with:
strcpy(text,shots);

I've tried a couple of other permutations, including changing the next line to:
nokiaLcd.lcd_draw_text(CYAN, BLACK, 40, 90, shots);

I get:
error: invalid conversion from 'long int' to 'char*'

I'm using a Diecimila to drive the board, and so far things have been flawless.  I've looked for ways to "Cast" the variable, but char(shots) doesn't seem to work either.

Thank you

Hi...i got the LCD to show up text and clear up fine. Thank you so much everyone. I was wondering if the library can be used to show photos?


bofo

Hi. I just got the SparkFun breakout board working wih Arduino.

I used the code from Arduino Playground -- Epson S1D15G10 Nokia LCD (Work In Progress)

I can see the test pattern (Purple Yellow Orange) when I view the display from an angle. But if I look at the display straight-on, all I see is Blue -- or maybe 3 shades of Blue.

Any ideas what I need to do to get display o look right?

Thanks!
