Alexander Medvedev / medvdv5110

light text library for 5110 nokia lcd * easy to modify * proportional font, bold / inverse modes * easy to add / change fonts * fixed rows for fast update

Library finished! :-) If you use 5110 and need fast menus - try this library. No overhead - small and robust, optimized for this display type only, fast update. Nice looking font. Power management. Displays from 5110 and 3110 are cheap as dirt :-)
