Chapter 7 — Numbers on the Six-Digit Display
This chapter will teach the seven-segment display as numeric output before teaching full scan loops.
Planned coverage:
- what a seven-segment glyph is
- why digits are stored as segment bit patterns, not as ASCII
- MON-3 conversion helpers such as byte-to-segment and ASCII-to-segment
- preparing a six-byte display buffer
- using MON-3 to scan segment data
- displaying a counter, key code, or score-like value
The important idea is representation: a number in A or HL is not yet display data. You must convert it into segment patterns before the hardware can show it.
