Enumeration Type Documentation

Regs

enum duds::hardware::devices::instruments::FXOS8700CQ_internal::Regs

The registers.

They have been renamed to be more readable, understandable, and consistent. The names in the documentation have the odd property of explicitly stating when something is for the magnetometer, but not always doing the same for the accelerometer.

Enumerator
RegStatus	STATUS. Holds either accelerometer data status, or FIFO status.
RegSamples	OUT_X_MSB. This is the start of the latest accelerometer sample when the FIFO is not used, and the start of the oldest samples when the FIFO is used. When both the accelerometer and magnetometer are in use, samples from both are read starting from here. The documentation states in a terse summary text that the FIFO buffer is for accelerometer data only, but the in-depth documentation on reading from the FIFO seems to imply that the magnetometer data is also buffered mostly because it doesn't restate that the FIFO isn't used for the magnetometer, and overlooks this detail in its otherwise detailed description of address increments. The only way the documentation is correct is if reading from the FIFO is followed by reading the latest magnetometer sample, in which case the two samples may not have been taken consecutively.
RegFifoConfig
RegFifoTrigger
RegSystemMode	SYSMOD, the system operating mode and FIFO error status.
RegIntFlags
RegDeviceId
RegAccelConfig	XYZ_DATA_CFG.
RegFilterConfig	HP_FILTER_CUTOFF.
RegConfig1
RegConfig2
RegConfig3
RegConfig4
RegConfig5
RegAccelOffsetX	OFF_X.
RegAccelOffsetY
RegAccelOffsetZ
RegMagStatus
RegMagSample	M_OUT_X_MSB. This is the start of the latest magnetometer sample. It is followed by the accelerometer sample that the documentation describes as "time aligned", which I suppose means they were taken consecutively. This may make the accelerometer sample older than the one at RegSamples, but by no more than one sample period.
RegMagOffsetX
RegMagOffsetY
RegMagOffsetZ
RegMagConfig1
RegMagConfig2
RegMagConfig3
