 - It may or may not work.
 - It could crash the display firmware, requiring a power cycle.
 - It could even brick the display firmware.

 - [x] Reverse engineer the LCD serial protocol to provide open screen software.
     - Utilize the official AOOSTAR-X display software by sniffing USB communication, using `strace`, and decompiling the Python app.
 - [x] Document known commands so clients in other programming languages can be written.

+A release build is highly recommended, as it significantly improves graphic rendering performance:
 
 ```shell
-cargo build --release --bins --all-features
+cargo build --release
