Going back to electronic after a 20 years break

 One bit per pixel font are a bit harsh on the eye. Let's increase the bit-per-pixel to 2, that is a pixel can have a value between 0 and 3. The above pic is one bit per pixel                                                                That one is two bits per pixel. It's not that obvious, but the 2bpp one is much nicer to look at, especially with very small fonts. Of course,  it basically doubles the flash size consumed by the font bitmap. Unfortunately, the  rule seen previously still applies : Compression is not working for small fonts. But for big fonts you get anti aliased font for ~ free (flash size), and for cheap er for medium fonts. In terms of code size : Adding 2 bits per pixel support : +~ 500 bytes Adding compression support :     + ~2kBytes In terms of speed, if we ignore the SPI/p...
