Using Nokia 3310 LCD

The Nokia 3310 is a graphic display that is very cheap. In fact, they cost $2.95 each at Sparkfun http://www.sparkfun.com/commerce/pro...oducts_id=9924, (but come without connector). Or a 5110 on an easy to work with proto board, which is compatible with the 3310 here: http://www.sparkfun.com/products/10168 for $7.95. They are great for low power applications. The trouble is, the controller is not as smart as a regular LCD, so much of the controlling has to be done in code. The code here focuses on displaying text and variables on the LCD. Here are the specifications for the display:

Technical characteristics :

• Voltage ....................... 2.7 - 3.3 V
• Range ......................-55 do 125' C
• Min. temp. step ............ 0,1 ' C

• Temp. refreshed every.... 1,2 sec.
• Dimensions ................... 40 * 38 mm
• 2 modes of display .......normal/inverse
• Lcd ............................. 84 * 48 pixels
• Amperage ................... 0,2 mA - 0,8 mA

Attached is an include file for the Nokia 3310 LCD that has been modified from Gusse's code (in this thread Post 93 in the thread http://www.picbasic.co.uk/forum/show...0209#post70209 ), adds Darrel's PrintStr function, and a modified form of it for printing variables.

Using this include makes it much easier to use this LCD.


Here is an example of writing different text on separate lines:

You can also print different things on the same line, by using the x, and y, positions.


Ok, the printing a variable solution:
got a little old. So I managed to write my first macro (PrintVar), using Darrel's PrintStr as a base.

This makes it a lot easier with a one liner:
I also edited the PrintStr function to scroll to the next line when it runs past the end of the current line.
