* 7489 - include GNU UnifontKartik Agaram2021-01-098-26/+552
| | | | | | | https://en.wikipedia.org/wiki/GNU_Unifont#The_.hex_font_format http://unifoundry.com/unifont/index.html Since GNU Unifont is covered under the GPL v2, so I believe is this repo.

* 7486 - primitive for reading keysKartik Agaram2021-01-093-0/+74
| | | | | It also clears keys after reading them, allowing us to read more than 16 keys.

* 7480 - baremetal/ex3.hex now draws multiple pixelsKartik Agaram2021-01-072-7/+15
| | | | | | | | | | I was wrong in commit 7437 that only one keystroke was working. The problem was just that I was getting _too_ many events. I wasn't handling key-up events, and they were entering the buffer, and I was not skipping null events since the circular buffer is currently considered to be null-terminated. ex3 isn't done yet; it can only handle 16 events. Apps need to be clearing the keyboard buffer.

| | | | | | | The ol' 8-byte-register-names issue strikes again. There's no way to access the lower 8 bits of ESI. There's still a bug in baremetal/ex2.mu; it's printing transposed somehow.
* 7469 - first working baremetal Mu programKartik Agaram2020-12-295-0/+104
| | | | | It doesn't _quite_ do what it should, so this is more precisely the first _buggy_ baremetal Mu program. But the tooling works, at least.

| | | | | | | | | | New approach to disambiguating /disp32 arguments: based on opcodes rather than metadata. I interpret /disp32 as PC-relative in a short list of instructions. Otherwise it's absolute if it gets a label. There should be no reason to pass labels into /disp8 or /disp16.

| | | | Go back to commit 7448.
* 7453Kartik Agaram2020-12-281-74/+23
| | | | | Snapshot: this approach of disambiguating /disp32 based on metadata doesn't work. The `survey` phase runs after `pack`, which gets rid of most metadata.
