Description
Code for one of these characters: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, /, (space), :, –, (comma), (period)
Depth of the bit map is 1 bpp
Note:
It is the responsibility of the user to set up proper values in the character positioning to
fit them in the same row (that is one of the reasons that 22 is the maximum number of
characters).
No error is generated if the character row overruns the horizontal or vertical limits of
the frame.
