altos: Intgrate hmc5883 sensor into adc ring

2012-06-03T00:12:27+00:00

Creates a task to poll the mag sensor and place the data into the sensor data ring. Signed-off-by: Keith Packard

altos: Add support for MegaAccel daughter card.

2012-06-02T06:07:38+00:00

Switches all acceleration computation to using the MegaAccel accelerometer to ensure support for high-g flights. MPU6000 values continue to be logged as normal Signed-off-by: Keith Packard

altos: Make telemetrum-v1.1 compile with new ao_data structure

2012-05-27T23:24:09+00:00

Signed-off-by: Keith Packard

altos: Don't start ADC ring until the other sensors have a valid value

2012-05-27T22:46:00+00:00

Yes, this is still an ugly kludge, but it's easy. Signed-off-by: Keith Packard

altos: Data packet tick count does not live in adc structure

2012-05-27T22:44:38+00:00

It was moved to the global structure. Having two is confusing. Signed-off-by: Keith Packard

Get megametrum ready to at least log flight data

2012-05-26T05:18:06+00:00

Doesn't track flight state changes correctly. Signed-off-by: Keith Packard

altos: stm: pass DMA buffer index to DMA completion callback

2012-05-08T04:50:26+00:00

This lets the user know which DMA has finished. Signed-off-by: Keith Packard

altos: Allow STM DMA channels to be reserved for one use

2012-04-09T07:05:18+00:00

This allows a single user of a DMA channel to reserve it for use without needing to lock the mutex; this is required for DMA from the ADC to work on megametrum as it wants to start DMA from an interrupt handler, which cannot block on a mutex. Signed-off-by: Keith Packard

altos: Use 384 cycle ADC sample time

2012-04-08T03:33:27+00:00

This is plenty fast, and provides nice stable readings. Signed-off-by: Keith Packard

altos: Add support for STM ADC

2012-04-08T01:53:12+00:00

DMA-based driver for the STM analog to digital converter. Signed-off-by: Keith Packard
