Eight-Pin Graphics Modes
All 8-pin graphics functions require parameters, n1 and n2, which
represent the length of the graphics string that follows the select graphics
mode command, and are calculated as follows (assuming a temporary
variable n):
•
n = total number of graphics dots needed for the graphic string
•
n2 = integer of (n divided by 256)
• n1 = remainder of the n2 calculation
The simplest calculation, is to divide n (total number of dots needed for
the graphics string) by 256. Then n2 is the quotient (the whole number)
and n1 is the remainder. If you require less than 256 dots (columns), then
n1 indicates the number of dots and n2 is set to zero.
