The command clears bit image logo data from RAM. The illustration below provides a
sample of a character cell.
Defining User-Defined Characters
Defines and enters downloaded characters into RAM.
Values and Ranges:
c = the ASCII codes of the first (c1) and last (c2) characters respectively
c1 = Hex 20-FF (Hex 20 is always printed as a space)
c2 = Hex 20-FF (Hex 20 is always printed as a space)
To define only one character, use the same code for both c1 and c2.
n = the number of dot columns for the nth character as specified by n1 ... nn
n = 1-10 (standard pitch), 12 and less accepted but ignored
n = 1-8 (compressed pitch), 12 and less accepted but ignored
d = the column data for the nth character as specified by d1 ... dn
The number of bytes for a particular character cell is 3 x n1.
The bytes are printed down and across each cell.
