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: Get HMC5883 driver limping along

2012-06-02T23:57:22+00:00

Not pushing data into the ring yet, but the chip appears to work now. Signed-off-by: Keith Packard

altos: Reset i2c controller at boot time

2012-06-02T23:56:41+00:00

In case it's wedged. Signed-off-by: Keith Packard

altos: Fix broken EXTI edge mode selections. Clear pending exti on enable

2012-06-02T23:54:42+00:00

Make sure the edge mode registers are set according to the requested mode. Clear any pending interrupt when enabling to avoid spurious isr call Signed-off-by: Keith Packard

altos: Route correct GPIO line to interrupt controller

2012-06-02T23:53:46+00:00

Which GPIO a particular pin interrupt comes from is selected by the SYSCFG EXTICR registers; set these when an exti interrupt is configured. Signed-off-by: Keith Packard

altos: Enable some debugging during flight mode on MM

2012-06-02T21:58:00+00:00

Until we've got the radio working, there's no way to see inside the MM state without using USB. Add a diagnostic command to dump out the internal flight state variables. 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: Timers clock base depends on perhipheral bus prescalers too

2012-06-02T02:35:33+00:00

For some weird reason, a non-unity perhipheral bus clock scaler affects the base of the various timers; this left the 100Hz tick running at 200Hz. Signed-off-by: Keith Packard

altos: megametrum has logging

2012-06-02T02:35:01+00:00

This makes sure the various other subsystems know about it, like the 'v' command. Signed-off-by: Keith Packard

altos: add high-z accel and mag sensor to megametrum logging

2012-06-02T02:34:17+00:00

These nicely fill the 32-byte sensor log record Signed-off-by: Keith Packard
