altos: Have 'make clean' remove all programs, even old ones

2012-07-11T20:49:26+00:00

This makes sure that changing version numbers doesn't leave old compiled output lying around. Signed-off-by: Keith Packard

altos: Rename _mm.c back to .c

2012-07-10T22:11:36+00:00

Was just a temporary hack to keep cc1111 products building during MM development. Signed-off-by: Keith Packard

altos: rename ao_viterbi.c to ao_fec_rx.c

2012-06-27T05:16:44+00:00

Keep it parallel with ao_fec_tx.c Signed-off-by: Keith Packard

altos: improve FEC apis to reduce data copying

2012-06-23T23:05:42+00:00

Integrate interleaving and whitening into encode and decode steps. Add CRC checking function for receive. Make ao_fec_test program round-trip the data and verify correctness. Signed-off-by: Keith Packard

altos: Make ao_fec_tx_test build cleanly with -Wall

2012-06-23T09:13:52+00:00

Signed-off-by: Keith Packard

altos: Add the simplest possible viterbi decoder

2012-06-23T06:12:02+00:00

I think I understand how it works now. It's not exactly speedy, and it uses a lot of memory. Signed-off-by: Keith Packard

altos: Software implemenation of CC1111 radio encoding

2012-06-17T23:17:00+00:00

Add CRC, whitening, FEC and interleaving routines for transmission path to allow cc1120 to send telem packets to cc1111. Signed-off-by: Keith Packard

altos: Make telescience-v0.1 build with new ao_data struct

2012-05-27T23:44:01+00:00

Signed-off-by: Keith Packard

altos: Add conversion between Pa and meters

2012-05-19T03:19:01+00:00

To be used with the MS5607 which generates data in calibrated units. Signed-off-by: Keith Packard

altos: Improve TM v1.0 apogee estimate

2011-10-09T04:23:16+00:00

v1.0 boards have noisy accelerometer data caused by interactions between RF transmission and the accelerometer measurements; this noise generates a negative bias in the accelerometer readings. The net effect is that the estimated speed is lower than the actual speed, causing early an apogee estimate. By increasing the sigma value for accelerometer data, the kalman filter 'trusts' the acceleration data less, putting more weight on the barometer data. This causes the estimated time of apogee to be closer to the correct value. This reduces the response to changes in acceleration. This new value is applied solely to TeleMetrum v1.0 boards. v1.1 boards correct for this error, and hence can use the correct sigma value for the accelerometer. Signed-off-by: Keith Packard
