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.

Implement a (key) word that interpret keystrokes from the
|
|
builtin keyboard. The word waits for a digit to be pressed and
|
|
returns the corresponding ASCII value.
|
|
|
|
This routine waits for a key to be pressed, but before that, it
|
|
waits for all keys to be de-pressed. It does that to ensure
|
|
that two calls to _wait only go through after two actual key
|
|
presses (otherwise, the user doesn't have enough time to
|
|
de-press the button before the next _wait routine registers the
|
|
same key press as a second one).
