Recipes contain bits and pieces of hardware-related knowledge, but these bits feel sparse. I've been wanting to consolidate hardware- related documentation for a while, but always fell at odds with the recipes organisation. We don't have recipes anymore, just a /doc/hw section that contains hardware-related documentation which often translate to precise instructions to run Collapse OS on a specific machine. With this new organisation, I hope to end up with a better, more solid documentation.

TI-84+ LCD driver
|
|
|
|
Implement (emit) on TI-84+ (for now)'s LCD screen.
|
|
Load range: 555-560
|
|
|
|
The screen is 96x64 pixels. The 64 rows are addressed directly
|
|
with CMD_ROW but columns are addressed in chunks of 6 or 8 bits
|
|
(there are two modes).
|
|
|
|
In 6-bit mode, there are 16 visible columns. In 8-bit mode,
|
|
there are 12.
|
|
|
|
Note that "X-increment" and "Y-increment" work in the opposite
|
|
way than what most people expect. Y moves left and right, X
|
|
moves up and down.
