Firmware for blinkenrocket
Use `make && sudo make program` to flash a blinkenrocket and
`cd utilities; ./modem_transmit` to load example patterns.
## Known Bugs / TODOs
* Patterns longer than 252 bytes (excluding headers) are not yet supported
* Patterns longer than 28 bytes (excluding headers) can be saved, but only the
first 28 bytes will be displayed
* Only slow transmissions are reliable at the moment (16kHz and a few
ms of silence between patterns)
* The first `./modem_transmit` call does not work reliably --- Calling it a
second time immediately afterwards (or a few seconds later) works fine
