* altos: Increase STM SPI speed to PCLK/4Keith Packard2012-04-09
| | | | | | The pressure sensor seems happy at this speed. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Move MS5607 configuration to ao_pins.hKeith Packard2012-04-09
| | | | | | Which SPI port and where chip select is to be found are product specific. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add missing parens in ao_ms5607.hKeith Packard2012-04-09
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Reduce MS5607 reset delay, increase conversion delayKeith Packard2012-04-09
| | | | | | | Reset doesn't take very long, while doing a conversion seems to take more than 10ms. Signed-off-by: Keith Packard <keithp@keithp.com>
* 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: Add beeper driver to STM archKeith Packard2012-04-09
| | | | | | Drives the MegaMetrum beeper Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: ARM -O0 flag appears to generate buggy codeKeith Packard2012-04-09
| | | | | | Use -Os always, which is annoying... Signed-off-by: Keith Packard <keithp@keithp.com>
* 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: add STM I2C driver.Keith Packard2012-04-09
| | | | | | Not well tested yet... 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. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Show temperature in stm-demoKeith Packard2012-04-07
| | | | | | Use the ADC to show current temperature Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | This is plenty fast, and provides nice stable readings. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add STM temperature sensor calibration dataKeith Packard2012-04-07
| | | | | | | Each stm32l has two-point factory temperature calibration data. Provide access to that for displaying temperature data. Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* 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>
* altos: Add support for STM ADCKeith Packard2012-04-07
| | | | | | DMA-based driver for the STM analog to digital converter. 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>

| | | | | | | | Some architecture specific stuff needs to use core altos code, so create new ao_arch_funcs.h files per architecture that get pulled in at the end of ao.h Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Oops. Set per-USART STM baud rate register instead of usart1Keith Packard2012-04-02
| | | | | | | Was accidentally always setting usart1 instead of the per-usart register. Didn't work too well for other usarts... Signed-off-by: Keith Packard <keithp@keithp.com>

* Use -Os for STM apps. Fix altos.ld to matchall .rodata* sectionsKeith Packard2012-03-28
| | | | | | | | Without .rodata*, it would stick the flash copy of the data on top of any further .rodata* sections. Fortunately, the linker catches that and complains... Signed-off-by: Keith Packard <keithp@keithp.com>
