Nokia 5110 display

[RobG 1,892]

Here's the code I am using to control 5110. It uses USCIB (2553) but USI (2231) can also be use without any problem or major updates.
There is still a lot of work to be done, but basic text and some graphics can be displayed with the current version.

Ive used the 5510. I didn't use hardware SPI, just bit banging. The code I wrote is pasted on the forums Here

[RobG 1,892]

Thanks, those Vop, Temp Coef, and Bias settings are perfect.

I'm still experiencing some random behavior though, someone did a really lousy job on the header so it could be cold solder or basically poor build quality of the display. I will get another one and see if this is just a problem with this unit.

 

BTW,

LCD_write(LCD_CMD, 0x20); // LCD in Normal mode (non inversed) /// This is set basic instruction set

LCD_write(LCD_CMD, 0x08); // ** TODO ** Unsure of this command here /// This is set display to "blank"

LCD_write(LCD_CMD, 0x0C); // ** TODO ** Unsure of this command here /// This is set display to "normal"

[RobG 1,892]

Updated first post, added code and video.

[gwdeveloper 275]

Nice work! I just grabbed a few of these from ebay on the cheap. Good timing!

[RobG 1,892]

Updated original post with new code.

Added simple graphic stuff, 8 x 8 pixel graphics can be displayed, rotated, and flipped.

Rotating is not very efficient, maybe there is another way of doing it. Alternatively, two images can be stored, normal and rotated 90, all other combinations can be achieved with flips.

 

[bluehash 1,581]

Looks good Rob. I have something coming up close to this, which will coincide with the opening of the store.

Should be done in a week.

What is the resolution on this display?

[bluehash 1,581]

Are the 5110 and 5510 different displays? D&D replies to a 5510 here.

Are the 5110 and 5510 different displays? D&D replies to a 5510 here.

 

Hmm.. Good catch BH.. Never noticed before.. I believe the code comes from the Nokia phones and they use the same LCD display in the 5110 and the 5510 models... We actually get to talk to the PCD8544 chip which does the actual heavy lifting which is what I named my library.

 

One of the suppliers of the screens is ideadstudio and they say..

Nokia 5110 LCD is low-cost, monochrome LCD with 84x48 display. It is popular for 8-bit AVR/PIC projects, search google for 'Nokia 5510 LCD', and you will find lots of resources.

 

My screen came from ebay aeons back and they called it 5110 and thats how I refer to it in my head. (My wifes eyes glaze over when I mention my electronics.. so it tends to be in my head)

[bluehash 1,581]

Np Thanks!

[RobG 1,892]

Some of my header stuff is based on Adafruit's 5110 library and I will take a closer look at their graphics functions to create my own.

I found a couple of bitmap converters for displaying bitmaps on the lcds

bitmap 2 LCD http://bitmap2lcd.com
lcd assistant http://en.radzio.dxp.pl/bitmap_converter/

The program stores the # of button press's in flash so when power is restored the count doesn't start over.
Maybe this will help somebody. :thumbup:
cheers

Thanks Timotet.

I'm moving this to Projects.

After creating a horizontal bar graph, I figured it's time to update my audio spectrum analyzer to 5110.

First step, update volt meter code to display vertical bars (I will post the code in volt meter topic once I optimize it.)

Are you doing all hard work that the MSGEQ7 did?
