 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
