* altos: Make STM clock configuration per-product. Fix 32MHz CPU speedKeith Packard2012-04-09
| | | | | | | | | | This moves all of the STM clock configuration into ao_pins.h so that each product can configure it separately. While doing this, I discovered that the flash memory mode (64-bit, prefetch, latency 1) wasn't actually getting set, which is why the CPU refused to work at 32MHz.

* altos: Make ms5607 driver do somethingKeith Packard2012-04-09
| | | | | | | It's loading prom values and converting sensor data, but it's getting the wrong answer at present. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Slow STM SPI down a bit so the MS5607 returns valuesKeith Packard2012-04-09
| | | | | | | It's still not working right, but at least it returns something other than all zeros... Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Allow STM DMA channels to be reserved for one useKeith Packard2012-04-09
| | | | | | | | | This allows a single user of a DMA channel to reserve it for use without needing to lock the mutex; this is required for DMA from the ADC to work on megametrum as it wants to start DMA from an interrupt handler, which cannot block on a mutex.

* altos: STM SPI is not using interrupts itselfKeith Packard2012-04-07
| | | | | | All SPI transfers are done via DMA, so the DMA interrupts suffice. Signed-off-by: Keith Packard <keithp@keithp.com>

* altosui: When computing flight stats, auto-detect boost timeKeith Packard2012-04-07
| | | | | | | | Detect when boost actually starts by looking for the last low acceleration value before the recorded boost time. This improves the computation of the boost state data. Signed-off-by: Keith Packard <keithp@keithp.com>
* altosui: Integrate accel speed from very start of eeprom recordKeith Packard2012-04-07
| | | | | | | | Don't wait for the flight computer to have detected boost--that's often several samples after boost actually occurred, which can leave a bunch of acceleration out of the speed computation. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Force radio channel to zero when setting frequencyKeith Packard2012-04-07
| | | | | | | Otherwise, the actual radio frequency will include the channel offset, which is not useful. Signed-off-by: Keith Packard <keithp@keithp.com>
