* altos: mpu6000 requires a delay during startKeith Packard2012-06-27
| | | | | | | I have no idea why this is required, but the mpu6000 will not come up and run if this isn't present. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: ao_ignite.c is no longer cc1111 specificKeith Packard2012-06-26
| | | | | | Move it to core Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add debugging code to check for stack overflowKeith Packard2012-06-26
| | | | | | | | Stack overflow often happens from interrupt handlers sitting on top of a task stack. Check for this during ao_wakeup as that is often called during interrupt processing. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Enable full flight computer functionality in MegaMetrumKeith Packard2012-06-26
| | | | | | This turns on everything that currently works Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Create a 32-bit 1MHz timer for use in profiling executionKeith Packard2012-06-26
| | | | | | | This provides a simple method for getting high-resolution timer data to use in performance tuning code. It's not used by default anywhere. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Abort radio receive when using flash memory on megametrumKeith Packard2012-06-26
| | | | | | | | | | Radio receive camps on the SPI bus, making it impossible to access flash memory. Abort any pending receive operation when trying to get to the flash part. Yes, this is a total hack. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make gcc happy with ao_telemetry_set_intervalKeith Packard2012-06-26
| | | | | | Using unsigned locals made GCC sad as it was compared with a signed value. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Turn radio-related bits of ao_flight_mm.cKeith Packard2012-06-26
| | | | | | Now that MM has full radio functionality, we can make it work right. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: custom hex printer for telemetry packetsKeith Packard2012-06-26
| | | | | | Using printf is way too slow with pdclib; just hand-write hex byte output. 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: Add GPS logging code for MegaMetrumKeith Packard2012-06-26
| | | | | | | MM uses a different logging format with larger log blocks, so restructure the GPS logging code to fill them up Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make cc1111 radio control functions staticKeith Packard2012-06-26
| | | | | | No need to publish these; they're all private to cc1111 Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clean up usage of port parametersKeith Packard2012-06-26
| | | | | | | | Make stm port parameters always be pointers; this avoids the confusion where some macros took '&port' and others took a bare 'port', and also unifies code to run on other processors in a consistent fashion. Signed-off-by: Keith Packard <keithp@keithp.com>
* altosui: Make libaltos recognise new USB idsKeith Packard2012-06-26
| | | | | | | libaltos has a small range of 'AltusMetrum' products to avoid opening other devices. We've got more IDs, so open up the range. Signed-off-by: Keith Packard <keithp@keithp.com>
* altosui: AltosSerial and AltosLink both tried to provide frequency settingKeith Packard2012-06-26
| | | | | | | | AltosLink owns all of the device configuration, so remove that from AltosSerial and make sure that AltosLink provides the right function signatures (wasn't using the new direct frequency setting command). 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: decode cc1120 received packetsKeith Packard2012-06-25
| | | | | | Call the fec decode function, compute RSSI and check CRC 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: Forgot ao_telemetry.hKeith Packard2012-06-25
| | | | | | Not much builds without this... 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 ao_viterbi.c to megametrum buildKeith Packard2012-06-23
| | | | | | | It's not used yet, just wanted to see how big the resulting object file was (492 bytes). Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: fix comment about decoding last byte of FEC dataKeith Packard2012-06-23
| | | | | | There aren't *any* forward bits to use when decoding the last byte. Signed-off-by: Keith Packard <keithp@keithp.com>
* 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>
* ao-tools: Support MM telemetry packets in ao-telemKeith Packard2012-06-21
| | | | | | Parse the new packet formats Signed-off-by: Keith Packard <keithp@keithp.com>
* altosui: Support MM telemetry packetsKeith Packard2012-06-21
| | | | | | | Required restructuring the whole telemetry system to provide abstract interfaces to flight data. 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>
* ao-tools: add rudimentary support for MM telemetry to ao-telemKeith Packard2012-06-17
| | | | | | Just pretends they're TM packets for now Signed-off-by: Keith Packard <keithp@keithp.com>
* altosui: Add rudimentary MM support to altosuiKeith Packard2012-06-17
| | | | | | | | | Decoded the MM sensor packets as if they were TM packets. Add the USB ids. Add class of 'altimeter' devices and match those instead of just telemetrum as appropriate. Signed-off-by: Keith Packard <keithp@keithp.com>
* altosui: Move product definitions from AltosUI to AltosLibKeith Packard2012-06-17
| | | | 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>
* altosui: Catch timeout errors when setting up TD telem monitoringKeith Packard2012-06-17
| | | | | | Close the port in this case so it can be used for other things. 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: Start making cc1120 radio workKeith Packard2012-06-15
| | | | | | RDF tones and radio calibration work now. Signed-off-by: Keith Packard <keithp@keithp.com>
