altos: Allow cc115l driver to be built without radio power control

2014-06-06T00:24:57+00:00

TeleGPS just wants full power, so remove the configuration option Signed-off-by: Keith Packard

altos: Switch APRS altitude encoding computation to fixed point

2014-05-31T00:32:52+00:00

APRS altitude is logarithmically encoded, so this implementation includes a fixed point log-base-2 function along with a bit of other fixed point stuff. This eliminates all floating point from TeleGPS, saving around 4kB of code space. Signed-off-by: Keith Packard

altos: Make MS5607 PROM a public variable

2014-05-26T04:11:23+00:00

This will let the fake flight code update it as necessary, without creating a new interface in ao_ms5607.c Signed-off-by: Keith Packard

altos: Expose ao_gps_set_rate from u-blox driver

2014-05-21T08:43:13+00:00

This lets applications set the desired GPS update rate to reduce power usage Signed-off-by: Keith Packard

altos: Fix cc115l debug build

2014-05-21T08:43:12+00:00

New compiler warning flags and moving to the nxp require a few minor changes in the code to make it work. Signed-off-by: Keith Packard

altos: Allow APRS to send just battery voltage

2014-05-21T08:43:12+00:00

Don't require apogee and main voltages as well Signed-off-by: Keith Packard

altos: Make quadrature debounce per-pin rather than per-device

2014-05-15T15:31:24+00:00

Debouncing per-pin means we don't lose transitions, which makes counting a lot more precise. Signed-off-by: Keith Packard

altos: Add LED test command to pca9922 driver

2014-05-13T05:50:41+00:00

This lets you control the LEDs from the command line to test things. Signed-off-by: Keith Packard

altos: Simplify quadrature tracking

2014-05-09T07:05:39+00:00

Set the timer to 200Hz for a 5ms debounce interval. Then, simply look for transitions ending in both bits in the encoder being off, which indicates the the encoder is resting in a detent. If bit '2' is turning off, the encoder was rotated clockwise, otherwise the encoder was rotated counter clockwise. This is a lot more reliable, although still not perfect.

altos: Clean up trailing whitespace in ao_pad.c
