* test: Accept micropeak CSV files for micropeak testingKeith Packard2013-02-04
| | | | | | | This interpolates the missing values to provide a reasonable testing environment for the Micropeak flight firmware. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add Kalman filter to MicroPeakKeith Packard2013-01-16
| | | | | | | | This filters altitudes more accurately and also allows tracking of acceleration, which is used to discard height data generated by ejection charge noise Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Average MPU6000 values on ground for later useKeith Packard2012-12-17
| | | | | | | Having long-term ground averages recorded to the eeprom file will make post-flight analysis of the data better. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Test APRS rounding by using coordinates near the boundaryKeith Packard2012-12-16

* altos: Add test scaffolding for APRSKeith Packard2012-12-05
| | | | | | | | This moves some test code out of ao_aprs.c and into ao_aprs_test.c, and then adds Makefile fragments to compile and run the resulting program, creating a wav file as output Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make skytraq reflashing code try both 9600 and 4800 baudKeith Packard2012-11-30

| | | | | | | This makes sure that changing version numbers doesn't leave old compiled output lying around. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Save some memory.Keith Packard2012-07-10
| | | | | | | A few minor space savings in ao_cmd.c and ao_config.c. Don't build unused conversion functions ao_altitude_to_pres and ao_temp_to_dC Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | | This lets us experiment with hard-decision and other possible soft_decision bit depths. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Rename *_mm.c back to *.cKeith Packard2012-07-10
| | | | | | Was just a temporary hack to keep cc1111 products building during MM development. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Crank up the gaussian noise in the FEC testKeith Packard2012-07-03
| | | | | | | | This lets us check to make sure our receive performance isn't degrading at all, instead of just making sure we can receive perfect packets well. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clean up radio CRC handlingKeith Packard2012-06-27
| | | | | | | 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 <keithp@keithp.com>
* altos: Optimize FEC encode and decodeKeith Packard2012-06-26
| | | | | | | | | | | | | 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 <keithp@keithp.com>
* altos: rename ao_viterbi.c to ao_fec_rx.cKeith Packard2012-06-26
| | | | | | Keep it parallel with ao_fec_tx.c Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Incremental viterbi decodeKeith Packard2012-06-25
| | | | | | | | Decode radio input one interleave block at a time. This overlaps the decode computation with the packet reception, leading to lower latency in an attempt to keep up with the transmitter. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Get cc1120 packet reception workingKeith Packard2012-06-25
| | | | | | Interrupt-per-bit, but it seems to work Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: improve FEC apis to reduce data copyingKeith Packard2012-06-23
| | | | | | | | | 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 <keithp@keithp.com>

* altos: Add the simplest possible viterbi decoderKeith Packard2012-06-22
| | | | | | | 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 <keithp@keithp.com>
* altos: Software implemenation of CC1111 radio encodingKeith Packard2012-06-17
| | | | | | | Add CRC, whitening, FEC and interleaving routines for transmission path to allow cc1120 to send telem packets to cc1111. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make telescience-v0.1 build with new ao_data structKeith Packard2012-05-27

* altos: Add conversion between Pa and metersKeith Packard2012-05-18
| | | | | | To be used with the MS5607 which generates data in calibrated units. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Respect apogee lockout time in flight algorithmKeith Packard2012-04-14
| | | | | | | | | | | This prevents any apogee detection from occurring until the specified number of seconds after boost. This also prevents the switch from accel+baro to baro only mode in the Kalman filter. The test frame work is also changed to look for Apogee lockout: in the eeprom input file. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clean up test scriptsKeith Packard2012-04-14
| | | | | | | | The flight test scripts were using invalid bash syntax. Clean that up and also switch the default flight directory to my new ~/misc/rockets/flights directory. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Massive product config cleanupKeith Packard2012-04-14
| | | | | | | | Support multiple serial ports more cleanly Split out parts of ao.h into separate feature header files Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Improve TM v1.0 apogee estimateKeith Packard2011-10-08
| | | | | | | | | | | | | | | | | | | | | 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.

* altos: Write xdata versions of memory functions1.0.9.1Keith Packard2011-10-07
| | | | | | | | | | | | | | | | These are significantly smaller than the general pointer versions from libc on the cc1111. Signed-off-by: Keith Packard <keithp@keithp.com> Conflicts: src/Makefile.proto src/cc1111/ao_adc.c src/cc1111/ao_packet_master.c src/core/ao.h Fix up the new makefiles
* altos: Restructure altos build to prepare for multi-arch supportKeith Packard2011-08-25
| | | | | | | | | | | | | | Split out sources into separate directories: core: architecture and product independent bits cc1111: cc1111-specific code drivers: architecture independent drivers product: product-specific sources and Makefile fragments util: scripts for building stuff This should have no effect on the built products, but testing is encouraged Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Reflect ao_flight split in ao_flight_test dependenciesKeith Packard2011-03-31
| | | | | | Need to rebuild ao_flight_test when any of the flight sources change Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Fix up flight code testingKeith Packard2011-03-22
| | | | | | | This automates flight code testing by reporting mis-detected apogee or main events. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Switch telemetrum over to kalman filterKeith Packard2011-03-22
| | | | | | | | | | | | This changes the full telemetry stream to include kalman data instead of the old ad-hoc flight data. It's compatible in that the packet sizes are the same so teledongle can receive either and figure out which it has received. A few plotting and testing tools are added to make validating the new code easier. Signed-off-by: Keith Packard <keithp@keithp.com>
