altos: Don't start ADC ring until the other sensors have a valid value

2012-05-27T22:46:00+00:00

Yes, this is still an ugly kludge, but it's easy. Signed-off-by: Keith Packard

altos: Finish ms5607 support

2012-05-19T03:19:01+00:00

This has the MS5607 polling once each tick for pressure and temperature and then saving that in a global variable. The command UI provides for dumping the prom data so that an eeprom file can have raw sensor data along with the conversion factors necessary to compute useful values. Signed-off-by: Keith Packard

altos: Check MS5607 CRC. Clean up MS5607 API

2012-05-19T03:19:01+00:00

It's not ready for flight yet, but at least it's sensible now. Signed-off-by: Keith Packard

altos: Add support for multiple SPI busses and sharing device drivers

2012-04-14T20:21:09+00:00

The STM32L151 has several SPI busses, and we want to use more than one, so add a 'bus' parameter to the SPI interfaces. To avoid wasting time on AVR and CC1111 processors which only use one SPI bus, elide those parameters from the actual functions by wrapping them with macros. Configuring chip select is now all macroized so that each chip can have its own version, allowing the STM to share the various SPI device drivers with the cc1111 and avr processors. Note that only the M25 driver has been ported; porting the others is 'trivial', but not necessary at this point. Signed-off-by: Keith Packard

altos: Reduce MS5607 reset delay, increase conversion delay

2012-04-10T05:21:46+00:00

Reset doesn't take very long, while doing a conversion seems to take more than 10ms. Signed-off-by: Keith Packard

altos: Make ms5607 driver do something

2012-04-09T07:09:18+00:00

It's loading prom values and converting sensor data, but it's getting the wrong answer at present. Signed-off-by: Keith Packard

altos: Add DMA, SPI and MS5607 drivers
