| Nokia 1100 lcd driver with graphics functions, big font size |
 Posted: Thu May 05, 2011 6:46 am |

This driver is for nokia lcd with PCF8814 controller for example 1100, 1110i... etc.
As you can see on picture, you can plot a line, circle, rectangle
and fill in these graphics.
you can also use different font size
one of the advantages of the driver is very similar with 128*64 GLCD with HDM64GS12 controller
besides, the disadvantage of this, the driver file uses a lot of ram about 775 bytes
enjoy it
