Pico Run-time Configuration
The Pico uses it’s flash storage to store some runtime configuration values.
Attributes
The Configuration System on the Pico uses a Protobuf message to serialize the configuration.
message ConfigProto {
/** Because this makes the message variable length we need options to say this is a callback message */
string rpiFwGitCommitHash = 1;
bool isIbusLogOutputEnabled = 2;
enum LoggingLevels {
Logging_NotSet = 0; DEBUG = 1; INFO = 2; WARN = 3; ERROR = 4; WTF = 5;
}
LoggingLevels enabledMaxLogLevelForIbusLog = 3;
LoggingLevels enabledMaxLogLevelForPrintfLog = 4;
//If enabled, always turn on the Pi4 power supply when we start up.
bool alwaysTurnOnRpiOnStatup = 5;
//If enabled, send a packet to turn on BMBT screen
bool alwaysTurnOnScreenOnIbusActivity = 6;
enum ScanProgram {
Scan_Program_NotSet = 0;
NONE = 1;
CLOCK = 2;
LINSTEROS_BOOTSPLASH = 3;
GOOSE_BOOTSPLASH = 4;
BMW_BOOTSPLASH = 5;
MENU = 6;
}
ScanProgram scanProgramOnBoot = 7;
enum VideoSource {
RVC = 0x0; UPSTREAM = 0x1; PICO = 0x2; PI = 0x3;
}
VideoSource videoSourceOnBoot = 8;
// https://github.com/piersholt/wilhelm-docs/blob/master/bmbt/4f.md
bool sendBMBTEncodingPacketOnBootup = 9;
enum VideoEncoding {
NTSC = 0; PAL = 1;
}
enum AspectRatio {
FourThree = 0; SixteenNine = 1; Zoom = 2;
}
VideoEncoding videoEncoding = 10;
AspectRatio aspectRatio = 11;
}Logging
These attributes set how chatty the pico logs are:
bool isIbusLogOutputEnabled = 2;
enum LoggingLevels {
Logging_NotSet = 0; DEBUG = 1; INFO = 2; WARN = 3; ERROR = 4; WTF = 5;
}
LoggingLevels enabledMaxLogLevelForIbusLog = 3;
LoggingLevels enabledMaxLogLevelForPrintfLog = 4;They can be turned down or off at run-time to preserve bandwidth on the Ibus between the pico and the pi.
Video Encoding
Some early BMBTs need a packet sent to set their video mode correctly. https://github.com/piersholt/wilhelm-docs/blob/master/bmbt/4f.md
I haven’t had a need to use this on my car or bench setups, but I put it in here in case someone does need it.
ScanProgram
This one is a bit of an easter egg
enum ScanProgram {
Scan_Program_NotSet = 0;
NONE = 1;
CLOCK = 2;
LINSTEROS_BOOTSPLASH = 3;
GOOSE_BOOTSPLASH = 4;
BMW_BOOTSPLASH = 5;
MENU = 6;
}
ScanProgram scanProgramOnBoot = 7;The LinsterOS bootsplash is the one that works the best with the menu. However, setting this to GOOSE shows my scout group’s logo. Some of the bootsplashes aren’t finished.
