read-sensor-status
wayland/bno055-aos/read-sensor-status
Reads status of bno055 sensor.
read-sensor-status
@/read-sensor-status
Reads status of bno055 sensor.
DEV@/bno055-device
A bno055 device.
UPDpulse
Update. Triggers new status reading.
DONEpulse
Pulses on completion of read.
SERRbyte
System error: 0 = no error;
1 = peripheral initialization error;
2 = system initialization error;
3 = self test result failed;
4 = register map value out of range;
5 = register map address out of range;
6 = register map write error;
7 = low power mode not available for selected operation mode;
8 = accelerometer power mode not available;
9 = fusion algorithm configuration error;
A = sensor configuration error.
TESTbyte
Self-test results: bit 0 = accelerometer self-test; bit 1 = magnetometer self-test; bit 2 = gyroscope self-test; bit 3 = MCU self-test. 0Fh = all good!
STATbyte
System status:
0 = idle;
1 = system error;
2 = initializing peripherals;
3 = system initialization;
4 = executing self-test;
5 = sensor fusion algorithm running ;
6 = system running without fusion algorithm.
