About Screen

My favourite screen to show in the car :)

Version Info

The about screen reports some version information:

AboutLabel("HMI: ${configurationStorage.versionConfig[HmiVersion.hmiHash]}")
AboutLabel("OS : ${configurationStorage.versionConfig[HmiVersion.sdHash]}")
AboutLabel("Firmware : ${
    configurationStorage
        .fwVersionAsFlow()
        .collectAsState(
            initial = configurationStorage
                        .versionConfig[HmiVersion.fwHash]
        ).value
}")

• HMI: The git hash of the e39-rpi project
• OS: The git hash of the system image
• Firmware: The hash of the Pi Pico firmware. It’s fetched from the pico itself at run-time. The Pico stores the hash as a string in its configuration object. When the HMI about screen opens, it sends a ConfigRequest, which then gets a reply from the Pico, which updates the value seen here.
