Public Member Functions
	UnitMPU6050 (const uint8_t addr=DEFAULT_ADDRESS)

Public Member Functions inherited from m5::unit::UnitMPU6xxx
virtual bool	begin () override
	Begin the unit.

virtual void	update (const bool force=false) override
	Update the unit.

config_t	config () const
	Gets the configuration.

void	config (const config_t &cfg)
	Set the configuration.

bool	writeAccelRange (const mpu6886::AccelRange range)
	Write the accelerometer range.

bool	writeGyroRange (const mpu6886::GyroRange range)
	Write the gyroscope range.

bool	readAccelRange (mpu6886::AccelRange &range)
	Read the accelerometer range from the device (REG_ACCEL_CONFIG bits[4:3])

bool	readGyroRange (mpu6886::GyroRange &range)
	Read the gyroscope range from the device (REG_GYRO_CONFIG bits[4:3])

bool	writeSampleRateDiv (const uint8_t div)
	Write the sample rate divider.

bool	readSampleRateDiv (uint8_t &div)
	Read the sample rate divider from the device (REG_SMPLRT_DIV)

bool	writeDlpf (const mpu6886::Dlpf dlpf)
	Write the digital low-pass filter bandwidth.

bool	readDlpf (mpu6886::Dlpf &dlpf)
	Read the digital low-pass filter bandwidth from the device (REG_CONFIG bits[2:0])

bool	softReset ()
	Soft reset (REG_PWR_MGMT_1 DEVICE_RESET), leaving the chip initialized but unconfigured and stopped.

bool	startPeriodicMeasurement (const mpu6886::AccelRange accel_range, const mpu6886::GyroRange gyro_range, const mpu6886::Dlpf dlpf, const uint8_t sample_rate_div)
	Start periodic measurement.

bool	startPeriodicMeasurement ()
	Start periodic measurement in the current settings.

bool	stopPeriodicMeasurement ()
	Stop periodic measurement.

bool	sleep () override
	Put the chip to sleep (REG_PWR_MGMT_1 SLEEP)

bool	wakeup () override
	Wake the chip from sleep()

virtual m5::imu::Capability	imuSpec () const override
	Capability of this unit.

virtual m5::imu::Capability	readImuRaw (m5::imu::imu_raw_data_t &out) override
	Read the latest raw IMU data.

virtual void	imuConvertParam (m5::imu::imu_convert_param_t &out) const override
	Gets the conversion parameters for raw IMU data.

Protected Member Functions
bool	accepts_whoami (const uint8_t id) const override
	Accepted WHO_AM_I id(s) for this chip; begin() rejects the device unless this returns true.

float	temperature_res () const override
	Temperature conversion: degC per LSB (imu_convert_param_t::temp_res)

float	temperature_offset () const override
	Temperature conversion: degC offset (imu_convert_param_t::temp_offset)

Protected Member Functions inherited from m5::unit::UnitMPU6xxx
	UnitMPU6xxx (const uint8_t addr=DEFAULT_ADDRESS)
	Protected: UnitMPU6xxx is abstract, constructed only by concrete derived chips.

virtual bool	start_periodic_measurement (const mpu6886::AccelRange accel_range, const mpu6886::GyroRange gyro_range, const mpu6886::Dlpf dlpf, const uint8_t sample_rate_div)
	Virtual: UnitMPU9250 layers its aux-bypass re-open on top (the config write here includes INT_PIN_CFG=0xC0, which closes the bypass)

bool	start_periodic_measurement ()

bool	stop_periodic_measurement ()

bool	read_measurement (mpu6886::Data &d)

bool	write_register8_verified (const uint8_t reg, const uint8_t val)
