altos: Record all failed sensors and report status at power up

2019-07-16T18:12:49+00:00

Use DATA bits to mark which sensors have failed, then report that in beeps at startup time to help diagnose hardware failures while still allowing the board to be used over USB. Signed-off-by: Keith Packard

altos/stmf0: Add 'ao_serial_shutdown'

2019-07-16T18:04:16+00:00

This powers down the UART logic on request. Signed-off-by: Keith Packard

altos: Allow ms5607 driver to either set ao_sensor_errors or panic

2019-07-15T20:26:30+00:00

Products that want to remain usable (over USB) after a sensor failure don't want to panic when the ms5607 fails, but products with limited ROM space don't want to have extra code to check for the sensor failure and panic. Change the MS5607 driver to allow either option, and then make the micropeak based devices use it. Signed-off-by: Keith Packard

altos/micropeak-v2.0: expose log and config commands over USB

2019-06-18T21:50:53+00:00

This lets AltosUI handle the eeprom data Signed-off-by: Keith Packard

altos: Directly compute radio tuning values from frequency

2019-05-04T04:51:28+00:00

The 8051 compiler doesn't support 64-bit ints, so the old code used an iterative method in 32-bit values. That could take a long time when the frequency was mis-entered in Hz or MHz instead of kHz. This direct-computation uses 64-bit ints, but takes a fixed amount of time for any inputs. Signed-off-by: Keith Packard

altos: Add preliminary TeleStatic v3.0 code

2019-04-22T01:30:43+00:00

This adds the pin definitions and all of the code except for the ads131a04 driver. Signed-off-by: Keith Packard

altos: Add MAX6691 and ADS131A0X data to ring if present

2019-04-22T01:16:41+00:00

Add these two devices as potential data sources to be added into the ring if available. Signed-off-by: Keith Packard

altos: Use ao_data_accel_invert when changing orientation value

2019-04-18T21:42:15+00:00

Instead of using AO_ACCEL_INVERT, use the macro which flips the values around. This fixes a bug with ADXL375 flight computers (EasyMega v2.0) where the accel cal values would be scrambled when changing orientation. Signed-off-by: Keith Packard

altos: ARM ABI requires 8-byte aligned stack

2019-03-19T00:15:16+00:00

This makes doubles on the stack (as for var-args functions) work Signed-off-by: Keith Packard

altos: add ao_time_ns API

2019-02-25T23:42:25+00:00

This provides nano-second resolution times by reading the systick value (which runs at 250ns ticks on stm). Signed-off-by: Keith Packard
