* altos/telefireone-v2.0: Definitions needed for MAX6691 driverKeith Packard2019-04-21
| | | | | | | Fix the DMA channel definition (STM starts values at 1 for unknown reasons). Add definition of the power enable bit for the timer. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: get ao_max6691 driver workingKeith Packard2019-04-21
| | | | | | | | | | | | | | | | | | The driver uses a timer connected to a DMA engine to measure pulse widths from the chip. We get 11 pulses for 4 channels; the first pulse is caused by the timer starting up, the next two are the marker pulse and then 8 more indicating the end of the high and low periods for each channel. The driver API returns the 8 pulse widths; the caller is expected to know what to do with those values as using them requires knowing the value of the configuration resistor and the characteristics of the thermistors. The test code assumes a 1k configuration resistor, using that it computes the resistance of the four thermistors. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos/lambdakey-v1.0: Fix obvious build errorsKeith Packard2019-04-21
| | | | | | | The code is too large to run on this device at this point, but at least it doesn't fail to compile? Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Use ao_data_accel_invert when changing orientation valueKeith Packard2019-04-18
| | | | | | | | 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 <keithp@keithp.com>

* altos/stm32f4: Need to read-back register after clock enableKeith Packard2019-03-18
| | | | | | | This was reported as necessary; I have no idea, but it's not expensive, so why not... Signed-off-by: Keith Packard <keithp@keithp.com>

| * altos: add ao_time_ns APIKeith Packard2019-02-25
| | | | | | | | | | | | | | This provides nano-second resolution times by reading the systick value (which runs at 250ns ticks on stm). Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos: Change default time type to 32-bitsKeith Packard2019-02-25
| | | | | | | | | | | | | | Offers additional range for internal use without increasing cost on 32-bit platforms. Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos: Fix several mis-specified time typesKeith Packard2019-02-25
| | | | | | | | | | | | Make sure AO_TICK_TYPE is used "everywhere", instead of uint16_t or other. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Fix ISR declarations to make them non-weakKeith Packard2019-02-21
| | | | | | | | | | In my zeal to eliminate warnings, I added declarations of all ISR functions to a shared header file. However, I managed to include the 'weak' declaration, which meant that the intended ISR functions were as weak as the 'default' ISR functions. This left all interrupts non-functional, which doesn't make for a happy program. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Remove AO_LOG_STATE from ao_log_telefiretwoKeith Packard2019-02-18
| | | | | | | | | | Telefiretwo never changes flight state, so these packets weren't going to be written. Also stop passing &log to ao_log_firetwo -- it always got the global anyways, just use it directly. Signed-off-by: Keith Packard <keithp@keithp.com>
