* altos/stmf0: Add faster USB pathKeith Packard2015-01-26
| | | | | | | | This adds a way to allocate private USB buffers for sending data without needing to copy it again. It requires ensuring that all accesses are 16 bits aligned to 16 bit boundaries. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stmf0: Fix linker scripts to make ao_boot workKeith Packard2015-01-26
| | | | | | | | The flash loader ended up assuming ao_boot was at the start of ram, while the application stuck it after the interrupt table (where it needs to go). Signed-off-by: Keith Packard <keithp@keithp.com>
* ao-tools: Add --wait option to ao-usbloadKeith Packard2015-01-25
| | | | | | | This waits forever for USB writes to complete, instead of timing out after five seconds. Useful when debugging the device. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add flash-loader to usbtrng-v2.0Keith Packard2015-01-25
| | | | | | Uses the new STM32F042 flash loading bits. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add self-flash support for STM32F042 processorKeith Packard2015-01-25
| | | | | | | Also moves the usual address for applications out of the way of the flash loader. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: USBtrng v2.0 hardware bringupKeith Packard2015-01-25
| | | | | | Gets the USB connection running and blinks the LEDs. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Initial STMF04x supportKeith Packard2015-01-25
| | | | | | Basic clock configuration, OS support, LED and USB drivers. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add support for TeleBT v3.0Keith Packard2015-01-24
| | | | | | | Add support to the BTM driver for non-CC1111 interrupts Add HW flow control to STM serial driver Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Fix double-buffered USB changesKeith Packard2015-01-22
| | | | | | | | These got merged when we were down in Auckland, but before they'd been finished. Transmitting worked fine, but receiving was mis-configuring the OUT buffer size in the hardware. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Get rid of some accidental debug codeKeith Packard2015-01-22
| | | | | | | I was debugging the accelerometer calibration code and left some printfs in it, which made TM run out of flash space. Signed-off-by: Keith Packard <keithp@keithp.com>
* Set version to 1.5.9.11.5.9.1Keith Packard2015-01-16

* altos/lpc: Switch LPC SPI driver to interrupt-drivenbdale-altosdroidKeith Packard2014-12-22
| | | | | | | This improves performance for SPI transfers, while allowing other tasks to get work done during longer SPI transfers. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Adjust CC1200 RSSI reporting valueKeith Packard2014-12-22
| | | | | | | | | On the test setup, we were about 13dB off, so tweak the settings to suit. This result wasn't tested; it's just a rough offset until we get a production run of TeleDongle boards back to do more systematic measurements. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Document cc115l power measured at RF setting 0x03 as -31.75dBmKeith Packard2014-12-22
| | | | | | | | We built a custom TeleGPS load for radio sensitivity measurements with the lowest documented power level setting (0x03), and measured the power out at that value of -31.75dBm on the test board. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/cc1200: With PQT wide open, we can't use PQT_REACHED for startKeith Packard2014-11-23
| | | | | | | | | Because we're allowing even signals only weakly correlated with the preamble through to sync detection, we can't use the PQT_REACHED symbol to tell when a packet header has been seen. Instead, just look for SYNC_FOUND. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/cc1200: Open up preamble detect to improve sensitivityKeith Packard2014-11-23
| | | | | | | Increase soft decision PQT value to max (15) to ensure that we detect even weak packets. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/cc1200: Wait for packet to be placed in FIFO during receiveKeith Packard2014-11-23
| | | | | | | | | | | | | This changes the receive code to use MCU_STATUS, waiting for MARC_STATUS1 to indicate that the packet is in the fifo before reading it out. It also fixes the receive timeout code to keep receiving if the preamble or sync have been seen when the timeout fires. This makes TeleLCO able to use short timeouts during scanning while still successfully receiving packets. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/teledongle-v1.8: Make this the same as teledongle v1.9Keith Packard2014-11-16
| | | | | | Remove RSSI LED blinking, add CRC error LED Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Allow TeleMega to be built without MPU6000Keith Packard2014-11-16
| | | | | | | Robert Braibish's board has a dead MPU6000; this fix lets the TeleMega firmware build without that driver so the rest of the board could be verified. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/microsplash: fix .gitignore to ignore resulting binaryKeith Packard2014-11-16

* altos: Reset interrupt flags before TX in CC1200 driverKeith Packard2014-11-06
| | | | | | | Failing to reset the flags set during interrupt leads to short-circuiting transmission and not a lot of packets going out. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/teledongle-v1.9: Switch to NXP processor as on prototype boardsKeith Packard2014-11-06
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Disable JTAG when using pins for GPIOKeith Packard2014-11-06
| | | | | | | JTAG is enabled by default, making those pins not support GPIO unless specifically configured. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Declare SPI send parameters as constKeith Packard2014-11-06
| | | | | | This matches STM Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Use other TeleDongle LED for CRC-invalid packet reportingKeith Packard2014-11-06
| | | | | | | Instead of blinking out some fake-o RSSI indication, just blink the red LED when a packet with a bad CRC is received. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Use AO_SPO_SPEED_FAST for CC1200Keith Packard2014-11-06
| | | | | | | This asks for the fastest available SPI speed, instead of fixing it to 8MHz, which may not be supported on every architecture. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Stop attempting to ramp power on CC115LKeith Packard2014-11-06
| | | | | | | | The PA register on the 115L isn't in any way monotonic, making the old code broken. Just rempve it instead of fixing it; we don't ramp anywhere else... Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Declare port register type only in arch headerKeith Packard2014-11-06
| | | | | | | Instead of defaulting to 8 bits, explicitly require declaration of the type of the port register for each architecture. Signed-off-by: Keith Packard <keithp@keithp.com>
* Move teledongle 1.9 to 1.8; there's a new 1.9Keith Packard2014-11-06
| | | | | | 1.9 is now the lpc11u14-based form-factor prototype board. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Rename microwater to microsplashKeith Packard2014-11-05
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Increase CC1200 SPI data rate to 8MHzKeith Packard2014-10-25
| | | | | | | This got set to 125kHz to make debugging with a logic analyzer easier and never changed back to a reasonable speed. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Fix up telemetry delay computationsKeith Packard2014-10-25
| | | | | | | | | | | | | | | | With RDF, APRS and telemetry all being sent at varying rates, computing when to send the next radio data is not as simple as sending telemetry and then figuring out whether to send RDF and/or APRS. Fix this by computing times for the next telemetry/rdf/aprs packet, and only sending each when that time has passed. Compute the delay until the next radio activity as the minimum time to any transmission. This also adds code to the config bits to reset the radio times whenever something changes that might affect which radio data to send next. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Perform cc1200 calibration less often. Tweak radio paramsKeith Packard2014-10-25
| | | | | | | | | | | This performs calibration after every 4 operations, or when the frequency changes. This reduces the time it takes to get to receive mode. This also makes the sync and preamble qualifiers more strict to reject bad packets. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Remove old AO_SEND_ALL_BARO bitsKeith Packard2014-10-25
| | | | | | | This was used for testing the original TeleMini which couldn't log data at full speed. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Build TeleDongle v1.9 by defaultKeith Packard2014-10-25
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Increase PQT value for cc1200 improving sensitivityKeith Packard2014-10-25
| | | | | | | | The PQT value indicates how 'good' the preamble is; higher values allow a lower quality of preamble to pass the test, permitting more packets to be decoded. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Sort out ao_gps_print altitude fetchingKeith Packard2014-10-25
| | | | | | | | | | ao_gps_print is used by both teledongle/telebt and the host-based GPS test code. The first instance uses the old internal GPS structure, containing just a 16-bit altitude while the second uses an ao_telemetry structure, which contains 32 bits split into two members. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/teledongle-v1.9: Add remaining code to complete the projectKeith Packard2014-10-24
| | | | | | This turns the prototype board into a full teledongle Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Complete cc1200 driverKeith Packard2014-10-24
| | | | | | | | | | Deal with differences between cc1120 and cc1200, including built-in packet support and various register changes. This now works to send and receive telemetry, as well as send APRS and RDF. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Expose telemetry altitude macros even without GPSKeith Packard2014-10-24
| | | | | | This allows for APRS testing in the new teledongle code Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Mark STM ao_spi_send as taking const pointerKeith Packard2014-10-24
| | | | | | We don't write to this, so let it be const for type checking Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add prototype TeleDongle v1.9 codeKeith Packard2014-10-05
| | | | | | | Lights up the hardware, sends carrier and RDF tones. A bit more cc1200 work to be done still. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Copy cc1120 driver to cc1200 driver and hack a bitKeith Packard2014-10-05
| | | | | | | | | | The cc1200 is similar to the cc1120, although many registers have changed. This driver can send a bare carrier and an RDF tone, but does not yet receive or transmit telemetry data. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Fix syntax error with ao_log_mega change.Keith Packard2014-10-04
| | | | | | Missed a semi-colon. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Record 32-bits for gyro calibration valuesKeith Packard2014-10-04
| | | | | | | | | The gyro ground calibration values are scaled by 512 to provide a bit more precision for the computations. This means they don't fit in 16 bits, so change the format of the flight log record. Also change the reported format so that AltosUI has a chance of figuring it out. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Handle antenna down in ao_flight_testKeith Packard2014-09-29
| | | | | | | Parse the Pad orientation config value and flip the accelerometer value back around in antenna down configuration. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make sure we drop the SPI mutex when aborting cc1120 recvKeith Packard2014-09-26
| | | | | | | | | | The cc1120 receive code is 'twisty', in that it acquires the SPI mutex in the middle of an interrupt handler so that it can quickly start the radio when the signal comes in. This means we have to be careful to drop that mutex in all paths which leave the receive code, including when the packet receive is aborted mid-way through the process. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make sure we don't beep out continuity twice in idle modeKeith Packard2014-09-11
| | | | | | | | | | | | | | If the battery voltage report takes longer than the initialiation sequence, we could get to the state reporting after the state had switched from startup to idle. This would result in continuity being reported the first time through the loop. Then, as the state had already changed, we'd pass through the while test and go back to report continuity a second time. Fixed by using the state remembered before beeping out the voltage to decide whether to report the continuity. Signed-off-by: Keith Packard <keithp@keithp.com>
