* Decode HDOP data from skytraq GPSKeith Packard2009-11-21
| | | | | | | | The hdop data was getting dropped on the floor, but is rather useful when deciding if the GPS position is crazy or not. This reports HDOP * 5 (giving a useful range of .2-50). Signed-off-by: Keith Packard <keithp@keithp.com>
* Reduce igniter firing time from 500ms to 50ms.Keith Packard2009-11-20
| | | | | | | Given that the system will brown-out with the longer pulse, it doesn't make sense to even try; failure at 50ms probably indicates a short. Signed-off-by: Keith Packard <keithp@keithp.com>

* Stop using SiRF state info.Keith Packard2009-11-15
| | | | | | | | With the switch to the skytraq GPS unit, we don't have the same level of detail in the GPS stream, so stop reporting that in the telemetry stream, in the UI and writing it to eeprom. Signed-off-by: Keith Packard <keithp@keithp.com>
* Add date to GPS data, captured from GPRMC packet.Keith Packard2009-11-15
| | | | | | | Pull the date out of the GPS stream and send it over the telemetry link and write it to the eeprom. Signed-off-by: Keith Packard <keithp@keithp.com>
* Add flight number to telemetry stream.Keith Packard2009-11-15
| | | | | | | | This makes it easier to tie the telemetry and eeprom files together as they're now both labeled with serial and flight numbers, which should be unique. Signed-off-by: Keith Packard <keithp@keithp.com>

* Loosen tolerances for main->landed transitionKeith Packard2009-11-14
| | | | | | | | | | | | | | | Detecting that the rocket has landed is required for the system to flush the eeprom log and re-enable the RDF beacon. This patch changes the landed state entry requirements for the accelerometer to require only that the accelerometer stay within a quarter of a g (down from 1/10g) and changes the testing interval from 20 seconds to 5 seconds. The requirement that the barometric altitude be within 1000m of the launch altitude and that the barometer change by no more than 0.05kPa are unchanged.

* Return radio to telemetry settings when packet system closed.Keith Packard2009-11-05
| | | | | | | To receive telemetry after disabling the packet system, the radio must be reconfigured for telemetry mode. Signed-off-by: Keith Packard <keithp@keithp.com>
* Add reboot command.Keith Packard2009-11-05

* Move ao_match_word from ao_ignite.c to ao_cmd.cKeith Packard2009-11-05
| | | | | | This is a generally useful command line utility. Signed-off-by: Keith Packard <keithp@keithp.com>
* Explicitly use USB I/O routines in packet codeKeith Packard2009-11-04
| | | | | | | | | Using the implicit stdio functions (putchar/getchar/flush) would result in essentially random redirection of each, depending on whether the packet code had characters available when getchar was called. This would cause lockups in putchar. Signed-off-by: Keith Packard <keithp@keithp.com>
* In USB pollchar, wait for packet before re-checking USB out lenKeith Packard2009-11-04
| | | | | | | | | This probably wouldn't actually cause a problem, but it seems more reliable to wait for a packet interrupt before re-reading the packet OUT len register. This could avoid spinning while waiting for a USB packet, which seems like a good thing. Signed-off-by: Keith Packard <keithp@keithp.com>
* In packet master, move USB flush from packet thread to echo threadKeith Packard2009-11-04
| | | | | | | | This keeps the packet thread from blocking on USB and also makes the flush happen after every packet (slightly more USB traffic, but packets are slow anyway). Signed-off-by: Keith Packard <keithp@keithp.com>
* Pass accel calibration over telemetry stream. Telemetry data format change.Keith Packard2009-11-03
| | | | | | | | | | | This allows the ground station to convert the accelerometer sensor values into acceleration and speed data. This requires a new telemetry data structure, and so TeleMetrum and TeleDongle units must be updated synchronously. ao-view will parse either telemetry stream, and the serial format from TeleDongle now has a version number to allow for future changes.

* Add two-point accelerometer calibration.Keith Packard2009-11-02
| | | | | | | Calibration now uses two values, one upside right and the other upside down instead of a single horizontal value. This allows the use of other accelerometers and compensates for variations in the divider circuit to provide more accurate data.

* Enable packet-based communcation to command processorKeith Packard2009-11-01
| | | | | | | This splits the packet code into master/slave halves and hooks the slave side up to the getchar/putchar/flush logic in ao_stdio.c Signed-off-by: Keith Packard <keithp@keithp.com>

| * Send 0-length IN packet to flush USB after full packetKeith Packard2009-10-10
| | | | | | | | | | | | | | | | | | USB bulk transfers are a sequence of maximum-sized packets followed by a short packet, which signals the end of the transfer. When the last packet of the transfer would be a full-sized packet, an additional packet of zero length is sent to signal the transfer end. Signed-off-by: Keith Packard <keithp@keithp.com>

* Set all of the values to reset the radio for telemetryKeith Packard2009-09-04
| | | | | | | | | | Was sizeof(rdf_setup) instead of sizeof(telemetry_setup) when resetting the radio back to telemetry data mode from rdf mode. With the length value removed from the rdf config, these two arrays are no longer the same length, and so the last config value was not set leaving the radio sending garbage. Signed-off-by: Keith Packard <keithp@keithp.com>
* Make RDF beacon only run on pad and after landing.Keith Packard2009-09-04
| | | | | | | | | | | | It's pretty much impossible to RDF the rocket during flight, and it interferes with the telemetry data stream. Leave it enabled on the pad so that radios can be tested, and then re-enable it once the rocket has landed. This patch also turns the rdf 'on' time into a parameter so it can be changed, and then sets that parameter to 500ms, once every 5 seconds. Signed-off-by: Keith Packard <keithp@keithp.com>
