Chapter 10 — One-Bit Sound
This chapter will teach sound as timed output.
Planned coverage:
- MON-3 beep, note, and tune helpers
- the speaker as a single output bit
- the speaker bit sharing the digit latch
- toggling the bit to create a tone
- duration counters and divider counters
- why sound service belongs in the same cooperative loop as display scanning
Sound is a good bridge between simple output and timed hardware service. A bit that changes once is a click; a bit toggled regularly becomes a tone.
