rodriguj 4:35757c8b7625 15 /* I believe this charset was taken from the compilation from Joseph Gil years ago
rodriguj 4:35757c8b7625 16 * when I needed a charset for a different (FPGA) project, but I cannot remember
rodriguj 4:35757c8b7625 17 * exactly the website I took it from.
rodriguj 4:35757c8b7625 18 * What I do remember is that the owner of the website claimed that this charset
rodriguj 4:35757c8b7625 19 * is in the public domain.
rodriguj 4:35757c8b7625 20 * This a complete (256 ASCII codes) 8x8 charset, using the 437 page code (original IBM)
rodriguj 4:35757c8b7625 21 * so you can use its graphic blocks to build decent text based GUIs without the need
rodriguj 4:35757c8b7625 22 * to use plot, line and circle primitives
