altos: Set APRS deviation to 3kHz

2013-05-06T23:08:52+00:00

I finally found a bunch of references to APRS on the net and they all appear to assume a 3kHz deviation. Let's see if this works better with Yaesu radios. Signed-off-by: Keith Packard

Revert "altos: Make APRS deviation configurable"

2013-05-06T23:04:02+00:00

This reverts commit a18d68da1b0b23a6089166fcd14a5bb5368f10f1. We're just going to use 3kHz for APRS

altos/test: Fix warning in ao_aprs_test

2013-05-03T08:07:06+00:00

Was not forward-declaring ao_radio_send_aprs, causing a warning Signed-off-by: Keith Packard

altos: Make APRS deviation configurable

2013-05-03T07:52:30+00:00

Maybe this will help the Yaesu VX-8GR receive our packets Signed-off-by: Keith Packard

altos: No need to set GPS tick in satellite packet

2013-05-01T16:40:59+00:00

It's already been set in the location packet, and doing it twice bumps TeleMetrum over the code space limit (yay!) Signed-off-by: Keith Packard

altos: Use SYSTICK on STM32L

2013-05-01T15:58:17+00:00

It's probably more power efficient than using one of the timers, and it's certainly easier to configure. Signed-off-by: Keith Packard

altos: Mark GPS telemetry packets with GPS time stamp

2013-05-01T15:56:57+00:00

This provides a reasonable accurate indication of the system time when the GPS location data was received, and also makes sure GPS packets get some timestamp when no other telemetry is being transmitted. Signed-off-by: Keith Packard

altos: Use separate exception stack on STM32L

2013-05-01T02:04:26+00:00

This reserves 512 bytes of memory for a stack, then makes sure that exceptions continue to use that stack while processes use the per-task stack. Signed-off-by: Keith Packard

altos: Reduce stack usage of FAT driver and logger

2013-05-01T01:57:53+00:00

Move some large stack arrays to static storage. Also eliminates some printf error messages which don't seem that useful except for debugging. Signed-off-by: Keith Packard

altos: Open up the DVGA gain to use all of the available settings

2013-04-30T07:12:44+00:00

We usually work in RF quiet areas; let the AGC hardware try all of the available gain settings. Signed-off-by: Keith Packard
