altos: Allow megametrum to be built without using the mag sensor

2012-06-28T06:03:33+00:00

I'm having trouble getting it working reliably, so we'll like disable it for now. This patch makes that possible. Signed-off-by: Keith Packard

altos: Unroll viterbi state loop for >30% performance boost

2012-06-28T02:45:22+00:00

9.3ms vs 14.7ms, a clear win. Signed-off-by: Keith Packard

altos: Clean up radio CRC handling

2012-06-28T00:17:44+00:00

Make the FEC code just set the CRC_OK bit like the cc1111 radio does; eliminates a bunch of weird conventions across the FEC API. Signed-off-by: Keith Packard

altos: Don't try to grab radio while firing MM igniters

2012-06-27T08:20:43+00:00

If you're in idle mode, you stop forever as the packet mode receiver will own the radio mutex forever. Signed-off-by: Keith Packard

altos: ao_ignite.c is no longer cc1111 specific

2012-06-27T06:26:32+00:00

Move it to core Signed-off-by: Keith Packard

altos: Add debugging code to check for stack overflow

2012-06-27T06:21:04+00:00

Stack overflow often happens from interrupt handlers sitting on top of a task stack. Check for this during ao_wakeup as that is often called during interrupt processing. Signed-off-by: Keith Packard

altos: Make gcc happy with ao_telemetry_set_interval

2012-06-27T06:15:54+00:00

Using unsigned locals made GCC sad as it was compared with a signed value. Signed-off-by: Keith Packard

altos: Turn radio-related bits of ao_flight_mm.c

2012-06-27T06:14:13+00:00

Now that MM has full radio functionality, we can make it work right. Signed-off-by: Keith Packard

altos: custom hex printer for telemetry packets

2012-06-27T06:13:14+00:00

Using printf is way too slow with pdclib; just hand-write hex byte output. Signed-off-by: Keith Packard

altos: Optimize FEC encode and decode

2012-06-27T06:11:10+00:00

Integrate interleaving, CRC and padding within the decode/encode functions. Provide for ISR priorities so that the 1120 RX interrupt takes precedence over the other interrupts or we risk losing bits. Optimize the viterbi decoder a bit (goes from 10ms per packet to 7ms per packet). Signed-off-by: Keith Packard
