If you are looking for the nokia lcd (bitmap to hex codes for 84X48 lcd with PCD8544, it can be accessed at the link here Nokia LCD Hex Generator
Scrolling text patterns on 8x8 led matrix displays forms one of the common and favorite arduino projects. It is necessary to set the led pixels in binary or hex to the corresponding led to be kept on. Example sketch can be viewed here
Here is an easy to use, web based online font generator. click on the matrix to toggle the led status to on or off and get the hex codes.

Hex values:


This can be used to generate fonts and patterns for using with arduino sketches. Insert the generated codes in the font or pattern definitions in the sketch. Both forms will work and the hex form will keep the source code small and neat. For example, see the following direct drive sketch. To generate a pattern , click on the grid and toggle it to on (1). Once you are done with the font / pattern, copy the binary values or hex values to your sketch.
