* 7480 - baremetal/ex3.hex now draws multiple pixelsKartik Agaram2021-01-071-1/+2
| | | | | | | | | | 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.

* 7437 - baremetal: draw pixel on keyboard eventKartik Agaram2020-12-281-0/+57
It's now clear that our keyboard handler doesn't trigger after the first event.
