* altos: Make ao_fec_tx_test build cleanly with -WallKeith Packard2012-06-23
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: optimize Viterbi implementationKeith Packard2012-06-23
| | | | | | Minimize data usage, make data arrays static Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: incremental viterbi decodeKeith Packard2012-06-23
| | | | | | | Decode bits incrementally. Don't bother decoding the last byte; it's always a pad byte. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Start optimizing viterbi decoderKeith Packard2012-06-22
| | | | | | | | Only need two cost arrays (previous and next). Create constant full-width decoder table instead of expanding bits into bytes for each decode step. 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: Move FEC code to coreKeith Packard2012-06-21
| | | | | | It's not a driver as it's not specific to the 1120 chip Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Crank down STM SPI speed for MMKeith Packard2012-06-21
| | | | | | | | The cc1120 is noisy enough to break SPI data transfers at 4MHz, so crank things down to 1MHz. It's "stable" now, but clearly needs a filter and shorter traces. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add full MM telemetryKeith Packard2012-06-21
| | | | | | | | Create two new telemetry packets to hold all of the MM data. This patch also splits the telemetry structures out of ao.h Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Configure STM LCD driver for giant LCD digitsKeith Packard2012-06-21
| | | | | | These devices require static mode. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make sure ao_storage_config is set before reading config blockKeith Packard2012-06-17
| | | | | | | | ao_storage_read does in fact call ao_storage_setup, but we need the value of ao_storage_config *before* calling ao_storage_read, so call ao_storage_setup first. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: hack STM serial number to 58Keith Packard2012-06-17
| | | | | | otherwise altosui won't record telemetry Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: make cc1120 ao_radio_send re-entrantKeith Packard2012-06-17
| | | | | | It gets called from multiple tasks, so put local data on the stack. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add telemetry to megametrumKeith Packard2012-06-17
| | | | | | Now that the radio works 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: Be more careful about register save/restore in ao_yieldKeith Packard2012-06-17
| | | | | | | Make sure the general registers are all saved before messing with any of them. Then, explicitly use r0 to save/restore apsr and primask. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Don't lose IRQ disabled state in ao_sleepKeith Packard2012-06-17
| | | | | | | | | | | | Using ao_arch_critical around the wchan setting will force interrupts to be re-enabled before ao_yield records the state of that bit, potentially causing problems with functions not atomically testing and sleeping. Tasks that need to set wchan with interrupts disabled should have interrupts disabled when entering ao_sleep already. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: ao_storage_read already calls ao_storage_setupKeith Packard2012-06-17
| | | | | | No need to call twice. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Use interrupts to wake up after RDF transmission.Keith Packard2012-06-17
| | | | | | Also clean up the debug output Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Crank cc1120 power down to 0dBm to avoid crashing CPUKeith Packard2012-06-17
| | | | | | | Looks like RFI from the transmitter is confusing the CPU; lower the 1120 power output from +14dBm to +0dBm to keep the CPU happy. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Reduce STM SPI data rate to 4MHzKeith Packard2012-06-15
| | | | | | cc1120 doesn't want more than 6.1MHz, otherwise it gets very angry. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Fix RDF mode data rate and PKT_CFG0 valueKeith Packard2012-06-15
| | | | | | | Changes tone to the desired 1kHz frequency and ensures the PKT_CFG0 has the right value. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Actually write cc1120 register valuesKeith Packard2012-06-15
| | | | | | Helps to not use 'read' mode when writing. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Configure cc1120 frequencyKeith Packard2012-06-15
| | | | | | | Set default conversion value, and pull the selected frequency calibration data out of the config block. Signed-off-by: Keith Packard <keithp@keithp.com>

* Allow product to override maximum number of command lists (NUM_CMDS)Keith Packard2012-06-15

| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: typo in ao_monitor prevented ground station from including codeKeith Packard2012-06-04
| | | | | | | This created ground station software that couldn't actually receive and report telemetry packets. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Legacy telemetry needs original ADC recordKeith Packard2012-06-04
| | | | | | | | The legacy telemetry packets included the raw ADC structure directly, so make sure that doesn't change further, allowing teledongle firmware to remain compatible with old TM firmware. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Remove unused AES code from teledongle and tidongleKeith Packard2012-06-04
| | | | | | Leave this out as neither of these products need it. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Remove accel_ref from pre v1.1 TM firmwareKeith Packard2012-06-04
| | | | | | | V1.0 needs RAM space for flash buffer, leaving too little room for this extra data. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Intgrate hmc5883 sensor into adc ringKeith Packard2012-06-02
| | | | | | | Creates a task to poll the mag sensor and place the data into the sensor data ring. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Get HMC5883 driver limping alongKeith Packard2012-06-02
| | | | | | Not pushing data into the ring yet, but the chip appears to work now. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Reset i2c controller at boot timeKeith Packard2012-06-02

* altos: Fix broken EXTI edge mode selections. Clear pending exti on enableKeith Packard2012-06-02
| | | | | | | | | Make sure the edge mode registers are set according to the requested mode. Clear any pending interrupt when enabling to avoid spurious isr call Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Route correct GPIO line to interrupt controllerKeith Packard2012-06-02
| | | | | | | Which GPIO a particular pin interrupt comes from is selected by the SYSCFG EXTICR registers; set these when an exti interrupt is configured. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Enable some debugging during flight mode on MMKeith Packard2012-06-02
| | | | | | | | Until we've got the radio working, there's no way to see inside the MM state without using USB. Add a diagnostic command to dump out the internal flight state variables. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add support for MegaAccel daughter card.Keith Packard2012-06-01
| | | | | | | | | Switches all acceleration computation to using the MegaAccel accelerometer to ensure support for high-g flights. MPU6000 values continue to be logged as normal Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Timers clock base depends on perhipheral bus prescalers tooKeith Packard2012-06-01
| | | | | | | | For some weird reason, a non-unity perhipheral bus clock scaler affects the base of the various timers; this left the 100Hz tick running at 200Hz. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: megametrum has loggingKeith Packard2012-06-01
| | | | | | | This makes sure the various other subsystems know about it, like the 'v' command. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: add high-z accel and mag sensor to megametrum loggingKeith Packard2012-06-01
| | | | | | These nicely fill the 32-byte sensor log record Signed-off-by: Keith Packard <keithp@keithp.com>
