Introduction
The firmware will be responsible for listening for serial commands, and then acting upon them. This will primarily involve changing the display.
Commands
Commands start with a one-byte identifier, followed by zero or more data bytes. The number of data bytes is command-specific. The device should not output any data unless specified below.
| Command | Action | Data |
|---|---|---|
| 00 | Reset display | None |
| Resets the display, initialising all pixels to black. | ||
| 01 | Identify | xx yy |
| Asks the device to identify itself. The controller sends its version number as two data bytes: major and minor version. The device will respond with a two-byte code containing its major and minor version. | ||
| 11 | Update floor | RR GG BB ... |
| Update the entire floor with the given pattern. | ||
