Hi

Been trying to connect a graphic lcd display from a nokia 3310 mobile phone without much luck These are only small lcds with a 84x48 display, but can be brought pretty cheap from ebay, alot cheaper than any other graphic lcd. They work with an SPI interface and only require 1 external cap.

just wondering if anyone here has done it and if they could share their circuit or code.

the only thing i think i could be doing wrong is using a 5v supply as the data sheet does say 2.8-3.3v but i have seen circuits on a couple of websites that use 5v.

Thanks in advance for any help,

Nigel: if you are reading, I think using one of these displays would make a great tutorial :wink:

I can see two major problems!.

1) Do you have the datasheet for the display, because without it live is going to be VERY difficult.

2) Presumably it requires large amounts of memory storage in the controlling device - this isn't something PIC's are very good at!.

yes i have the data sheet for the controller

http://www.deramon.de/datasheet/pcd8544.pdf

I was thinking of using an external eprom to contain the fonts and any images to display as used here

have a look at the following links

for if you know basic go to
http://www.mikroelektronika.co.yu/en...c/project0009/

if you like to use C then you could use one of the examples that comes with the CCS compiler.

thanks for the links, i got it working after the last time i posted, i just had the contrast set too low in the code

works great now, these lcds are excellent value.

 

Hi

i'm doin a project on weather station usin pic 18f452. n i'm confused hw to connect lcd to pic controller. I hav a doubt whether to connect lcd 3310 directly to pic 18f452 or use dat integrated controller pcd8544 as a interface between pic n lcd. pls any one help me regarding this confusion.


thank you

 

if you want to connect 3310 lcd to uC, you connect it as "any other SPI device", so directly, the only thing you need to worry about is "levels", 3310 lcd is 3V device so if your pic is running on 5V you need to shift levels from 5 to 3V (and vv for sdo). Check one of the many pages talking about it pcd8544 based displays (serdisplib)

 

Thank you.
