| | ===== QMC5883L Magnetometer ===== |
| | * device can switch between standby mode and continuous mode via writing to registers via I2C |
| | * the [[https://github.com/mprograms/QMC5883LCompass|mprograms library]] supports this |
| | * [[https://nettigo.pl/attachments/440|datasheet]] explains that reading/writing via I2C is still possible in standby mode |
