* altos: Change ao_mpu6000_gyro arg to floatKeith Packard2013-10-27
| | | | | | This lets callers pass more precision than just the original sensor value Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add gyro-based orientation trackingKeith Packard2013-10-25
| | | | | | | This tracks the angle-from-vertical as an additional input to the pyro channels. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Grab SPI mutex until MPU6000 I2C mode is disabledKeith Packard2013-05-15
| | | | | | | | If other drivers use the SPI bus, the MPU6000 gets confused as its sitting on the bus looking for I2C messages. Just grab the mutex before the OS is running and hold onto it until the MPU6000 has been initialized. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Document which MPU6000 revs have broken accel valuesKeith Packard2013-02-04
| | | | | | | | | From Tridge -- MPU6000 rev C4 and C5 are broken, having accelerometer values in the wrong range. This commit just adds comments which note this; experimentation will be required to actually sort out what's going on. Signed-off-by: Keith Packard <keithp@keithp.com>

| * altos: Define full-scale gyro and accel values for MPU6000Keith Packard2012-10-13
| | | | | | | | | | | | This lets other code convert MPU6000 readings into canonical units Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos: Go back to recording sensor data in globalsmm-ms5611Keith Packard2012-10-08
|/ | | | | | | | Instead of trying to get things into the ring from a variety of functions, go back to the simpler method of storing them in globals and having the ADC code just pluck out the most recent values. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Trigger sample complete when all data are readyKeith Packard2012-08-26
| | | | | | | This has each sensor mark a bit in the current data record which is then sent for processing when all of the data are present. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Don't start ADC ring until the other sensors have a valid valueKeith Packard2012-05-27
| | | | | | Yes, this is still an ugly kludge, but it's easy. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Poll mpu6000 values every tick and stash them locally.Keith Packard2012-05-18

* altos: Get mpu6000 workingKeith Packard2012-05-07
| | | | | | | This initializes the device appropraitely, and provides a command to dump the current values in converted form. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add mpu6000 and hmc5883 stubsKeith Packard2012-04-25
No real drivers here yet, just some testing stubs Signed-off-by: Keith Packard <keithp@keithp.com>
