5x7 chinese font
The 5 x 7 it's a standard dot matrix font. Try drawing on a paper with squares the new 4 x 7 fonts and see how will look like.
Especialy the M, N, W
Besides the MAX6953 has only 24 user-definable characters. Which ones from ASCII table you want to keep ?
User fonts are stored in MAX6953's internal RAM with five bytes per character.
Table 19 shows an example of data (characters 0, 1,and 2) being stored in the first three user-defined font
locations, illustrating the orientation of the data bits.
For character 2 you have (starting with address 0x8A for Font pointer):
Code:
Font Pointer address Register Data
0x8A 0x42
0x8B 0x61
0x8C 0x51
0x8D 0x49
0x8E 0x46
If you want to stretch to 4 x 7 matrix with one blank collumn then instead the above register data you have
Code:
Font Pointer address Register Data
0x8A 0x72
0x8B 0x49
0x8C 0x45
0x8D 0x42
0x8E 0x00
If you can accept this shape for char 2, the M char will look ugly (I don't want to say imposible to be drawn).
Thus the only solution is to have physical gaps between units.
