Chapter 11 — The 8x8 RGB Add-On
This chapter will introduce the 8x8 RGB matrix after the scanning model is already familiar.
Planned coverage:
- the matrix as an add-on, not the core TEC-1G display
- row selection
- one byte for the red pixels in a row
- one byte for the green pixels in a row
- one byte for the blue pixels in a row
- combining red, green, and blue planes into visible colours
- why one row is emitted at a time
- clearing the active row before changing colour data
- drawing a single coloured cell
The RGB matrix becomes the main visual programming target because it makes timing, representation, colour, and hardware refresh impossible to ignore.
