altos: Wire up another CC1120 GPIO to get MARC status changes

2012-12-17T00:04:05+00:00

When the radio drops out of RX or TX mode due to an error, it changes the MARC status, and sends pulse down a configured GPIO. Use this to tell when something 'bad' happened during TX or RX so that we can recover from losing the SPI bus in the middle of transmission or reception. Without this, the radio would change state and we'd never know, leaving the radio code waiting for an interrupt that would never arrive. Signed-off-by: Keith Packard

altos: Stop including profiling and stack guard code in megametrum

2012-12-08T06:49:34+00:00

These take CPU time and memory and are intended only for debugging Signed-off-by: Keith Packard

altos: Hook up APRS to telemetry loop

2012-12-06T18:23:39+00:00

Send APRS packet once every 2 seconds Signed-off-by: Keith Packard

altos: Hook APRS up to the radio

2012-12-06T18:12:11+00:00

This adds an arbitrary-length packet writing function to the radio code. Signed-off-by: Keith Packard

altos: Expose GPS serial fifo on MegaMetrum

2012-12-01T00:08:41+00:00

Necessary for direct access by the GPS reflashing code Signed-off-by: Keith Packard

altos/megametrum: Depend on Makefile contents for build

2012-10-25T07:07:14+00:00

This ensures that everything is rebuilt when the Makefile changes Signed-off-by: Keith Packard

altos: Add task queues.

2012-10-25T07:07:14+00:00

This replaces the array-based scheduler with a queue-based one instead. It should have the same basic scheduling semantics, but it walks shorter lists for each operation, making it much more efficient when the system has a lot of tasks. Signed-off-by: Keith Packard

altos: Add stack-guard code. Uses STM MPU to trap stack overflow.

2012-10-25T07:07:14+00:00

This marks the lowest portion of the stack as inaccessible to the CPU, causing the processor to fault when it reaches it. The fault then generates a panic message so that the user can know what happened. Signed-off-by: Keith Packard

altos: profiling on STM32L

2012-10-25T07:07:14+00:00

Add sample-based profiling, using a 1kHz timer Signed-off-by: Keith Packard

altos/megametrum: Switch back to using the MS5607

2012-10-18T22:34:41+00:00

We're planning to ship the MS5607 Signed-off-by: Keith Packard
