altos: Restructure altos build to prepare for multi-arch support

2011-08-26T03:49:11+00:00

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

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: New telemetry report format (version 4). Supports tiny telemetry.

2011-03-20T06:55:11+00:00

This completely replaces the version 3 format with a much simpler and easier to parse scheme. It's described in detail in ao_telem.h, but the basic idea is that the whole line is split into name/value pairs, separated by whitespace. Every name is unique, and the values are either strings or integers. No extraneous formatting or units are provided. Signed-off-by: Keith Packard

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

Log GPS data on pad after boost detect.

2010-02-14T00:42:27+00:00

This wakes up the two GPS reporting tasks and gets them to report out any existing GPS data to the log file. To make sure the timestamps in that GPS data are accurate, this also records GPS time on receipt of the GPS data instead of when that is logged. Signed-off-by: Keith Packard

Stop using SiRF state info.

2009-11-16T00:20:18+00:00

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

Add date to GPS data, captured from GPRMC packet.

2009-11-16T00:19:52+00:00

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

Add support for the SkyTraq GPS unit

2009-10-10T05:02:40+00:00

This is a build-time option selected by hacking the Makefile at present. Signed-off-by: Keith Packard

Handle GPS satellite tracking data

2009-08-19T05:35:15+00:00

SiRF message #4 includes signal strength and GPS engine state for each of the satellites being tracked. This data is now parsed and sent to eeprom and the radio. Signed-off-by: Keith Packard

Add AO_GPS_RUNNING state.

2009-07-18T04:32:17+00:00

This tracks whether the GPS receiver has ever sent a valid report to the flight computer, allowing the user to tell whether the GPS receiver is working at all. Signed-off-by: Keith Packard
