* altos: Mark GPS telemetry packets with GPS time stampKeith Packard2013-05-07
| | | | | | | | This provides a reasonable accurate indication of the system time when the GPS location data was received, and also makes sure GPS packets get some timestamp when no other telemetry is being transmitted. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Use separate exception stack on STM32LKeith Packard2013-05-07
| | | | | | | | This reserves 512 bytes of memory for a stack, then makes sure that exceptions continue to use that stack while processes use the per-task stack. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Reduce stack usage of FAT driver and loggerKeith Packard2013-05-07
| | | | | | | | Move some large stack arrays to static storage. Also eliminates some printf error messages which don't seem that useful except for debugging. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Open up the DVGA gain to use all of the available settingsKeith Packard2013-05-07
| | | | | | | We usually work in RF quiet areas; let the AGC hardware try all of the available gain settings. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Stop using telelco v0.2 top LEDS for radio TX/RXKeith Packard2013-05-07
| | | | | | | The top LEDs are now used for signal strength; a red LED indicates failed communcations, so we don't need to blink stuff and annoy the user. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make cc1120 driver return false on recv timeoutKeith Packard2013-05-07
| | | | | | Was returning an uninitialized value, which was often not zero Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Reconfigure CC1120 receiver to match our usageKeith Packard2013-05-07
| | | | | | | Open up the AGC to the full range. Set the AGC ref based on our receive BW (100kHz). Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Compute "real" RSSI value in radio code as neededKeith Packard2013-05-07
| | | | | | | | | Instead of dragging around the weird CC1111 RSSI values, just compute a dBm value in a signed 8-bit integer, ao_radio_rssi. Use that everywhere we need RSSI internally. We leave the weird CC1111 value in the packet reply as that's what the host expects. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: More .gitignore bitsKeith Packard2013-05-07

* altos: Build test framework for kalman filterKeith Packard2013-05-07
| | | | | | | This has some known flight data and generates kalman filter information for them to test Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Add nickle micropeak log parsing codeKeith Packard2013-05-07
| | | | | | I think this was just some debugging stuff, but it doesn't seem useless Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add telelco-v0.2 projectKeith Packard2013-05-07
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Allow LCD segments to not be multiplexed across digitsKeith Packard2013-05-07
| | | | | | | This allows each LCD segment to be individually configured as to which COM and which SEG drives it, permitting maximum flexibility in wiring. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clear any broken cc1120 TX fifo bits before transmittingKeith Packard2013-05-07
| | | | | | | | This just goes and clears the transmitter before using it, just in case it got wedged somehow. It also clears the bits while waiting for the radio to go idle, otherwise it'd never make it. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make cc1120 driver wait for TX finishedKeith Packard2013-05-07
| | | | | | | | | | Otherwise, we may come in and try to use the radio again too quickly, causing it to go into a TX fifo error state. This change watches the MARC status until the transmitter is explicitly marked as finished. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Provide timeout value to ao_radio_recvKeith Packard2013-05-07
| | | | | | | | | Instead of using ao_alarm around calls to ao_radio_recv, provide an explicit timeout value as needed by radio functions with more complicated system interaction than the cc1111. The timeout is 8 bits of clock ticks. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Build test framework for AES codeKeith Packard2013-05-07
| | | | | | Simple CBC-CMAC test with a constant 0 key and constant 0 data for now. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make telemega-v0.3 binary use the right nameKeith Packard2013-05-07
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Remove USB EP0 taskKeith Packard2013-05-07
| | | | | | | Handl EP0 actions from interrupt handler. This allows USB to be used in a taskless environment, like the STM flash loader Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Always declare all romconfig variablesKeith Packard2013-05-07
| | | | | | | | I haven't figured out how to assign addresses for specific initialized variables, so we'll just have to always declare all of them and make sure that we add new ones at the end. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Call ao_task_init before initializing any driversKeith Packard2013-05-07
| | | | | | | | When using task queues, the sleep queues must be initialized before any invocation of ao_wakeup or the OS will crash. Just make sure ao_task_init is always invoked early in the task process to get that done. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Expose ao_put_string functionKeith Packard2013-05-07
| | | | | | This works like puts, except it doesn't add a trailing newline. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: All STM ADC users need to declare HAS_ADC_TEMPKeith Packard2013-04-27
| | | | | | Otherwise we can't configure the ADC unit correctly at boot time Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Make SD card driver compile without radio supportKeith Packard2013-04-25
| | | | | | | | The SD card driver blocks the radio when trying to access the card as that operation appears very sensitive to RFI. This fix makes the driver work when there *isn't* a radio driver in the same device. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Re-generate TeleMega bitsKeith Packard2013-04-22

* altos: Make sure the packet format is set reasonably for radio testKeith Packard2013-04-12
| | | | | | Dunno if this matters, but it might as well be set reasonably Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Don't include bufio debug commands by defaultKeith Packard2013-04-12
| | | | | | We shouldn't need these Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Stick a mutex around FAT operationsKeith Packard2013-04-12
| | | | | | This allows the command line and logging operations to occur safely in parallel Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Delay while waking up SD card a bitKeith Packard2013-04-12
| | | | | | | | This seems to make bringing the card from idle to ready mode more reliable. If you spam the card with requests, it will eventually whinge and shut down communications. Signed-off-by: Keith Packard <keithp@keithp.com>
* altoslib/altosui: Carry receiver status around in AltosListenerStateKeith Packard2013-04-09
| | | | | | | | | | This moves the crc_errors into the new structure and adds a receiver battery voltage value there as well. Now the receiver status can be monitored separately from the flight status. That also means that code receiving state updates should be prepared to accept missing listener or flight state values. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Monitor battery voltage on telebtKeith Packard2013-04-09

* altos: Try RDF mode for TX calibrationKeith Packard2013-04-06
| | | | | | | | Trying to get the radio to stop modulating the carrier when calibrating the radio, we'll try RDF mode which says no preamble or sync data. This might shift the frequency though? Signed-off-by: Keith Packard <keithp@keithp.com>
* Set telegps USB id to 0025Keith Packard2013-04-02
| | | | | | It was accidentally using the same ID as megadongle... Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Shorten SD initialization timeouts.Keith Packard2013-04-02
| | | | | | This makes failure when no card is present much quicker. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Horrible kludge -- disable radio while talking with SD cardKeith Packard2013-04-01
| | | | | | | The SD card really doesn't like the RFI generated by our enormous radio, so just lock the radio out while working with the card. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add defines for the specific pins used for telegps SPIKeith Packard2013-04-01
| | | | | | These aren't needed at this point, but who knows? Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Retry SD card I/O. Use time for timeouts instead of countsKeith Packard2013-04-01
| | | | | | | | | | Sometimes I/O operations may fail; give the card a chance and retry the operation in case it works the next time. Replace the loop counts with loops that check the clock so that they'll have consistent timeouts even if the CPU or SPI speed changes. Signed-off-by: Keith Packard <keithp@keithp.com>
