altos: re-write a bit of GPS parsing code to reduce size

2011-08-14T01:44:26+00:00

Use a local variable while computing hdop. Place the next incoming character in data instead of pdata. Saved a surprising amount of memory. Signed-off-by: Keith Packard

altos: Switch ao_gps_skytraq and ao_gps_sirf xdata to pdata

altos: Complete new telemetry switchover

2011-07-05T06:39:21+00:00

This involved rewriting the GPS code to use the telemetry structures directly so that a memcpy could be used to transfer the data to the telemetry packets, saving a bunch of code space, along with fixing up the gps testing programs to deal with the structure changes. In addition, the teledongle code needed to have the monitoring code split into separate radio receiver and USB writer threads as the packets are now back-to-back, and hence come too fast to wait for the USB data to be sent to the host after each one.

altos: Add sat info to GPS report command

2011-07-05T01:06:48+00:00

Plan to use this to report current flight computer state in idle mode. Signed-off-by: Keith Packard

src/ao_cmd: Shave off bytes from doc strings

2011-03-07T08:01:46+00:00

Switch to using { func, "X args\0Desc" } to specify command, saving a char field by looking at help[0] instead, and reduce help length by doing alignment with printf instead of hardcoded spaces.

Revert "src/ao_gps_skytraq.c: Update logging rate to 10Hz"

2011-03-07T08:01:01+00:00

This reverts commit b080e933a65d268aaaec8cfd5f617a13d5babc43. 10Hz data isn't any better than 1Hz data; it still doesn't like going upwards rapidly.

src/ao_gps_skytraq.c: Update logging rate to 10Hz

2011-02-19T00:04:14+00:00

Send commands to skytraq to update baud rate to 57,600 bps, and set NMEA output rate to 10Hz.

src/ao_gps_skytraq: simplify parsing code

2011-02-19T00:04:14+00:00

Added macros to make correctly constructing skytraq commands easier. Simplified code path for NMEA processing marginally.

altos: Restructure skytraq NMEA parsing code to save some space

2011-01-16T22:34:54+00:00

Splitting this into several smaller functions appears to make SDCC generate better code.

altos: Bounds check Skytraq GPS tracking data array

2010-09-02T02:53:24+00:00

Missing GPS serial data could cause the tracking array reset to get skipped, causing the array to be overrun, smashing critical data beyond the array. This was detected using the 'altosui' flash command to program a device from TM. Hitting the USB that hard caused TM to crash with a mutex error (3 beeps) after the ao_gps_task structure was overwritten with zeros. Signed-off-by: Keith Packard
