altos/stm: Fix basic time interval to 10ms -- was 10.1ms

2012-09-09T20:57:16+00:00

Counting from 0 to 100 takes 10.1ms, so count to 99 instead. Signed-off-by: Keith Packard

altos: Oops. forgot ao_data.c

altos: Explicitly erase memory in STM eeprom driver.

2012-08-29T06:00:23+00:00

This seems to make the STM32L152 happier Signed-off-by: Keith Packard

altos: Fix ao_delay function and move from per-chip code to ao_task.c

2012-08-29T06:00:22+00:00

ao_delay hasn't been chip-specific for a long time, and it had a bug in not calling ao_clear_alarm. Signed-off-by: Keith Packard

altos: Enable STM SYSCFG when routing EXTI

2012-08-29T06:00:22+00:00

The EXTI routing information is in the syscfg unit, so that needs to be powered up or writes to its registers will be lost. Signed-off-by: Keith Packard

altos: No need to initialize EXTI priorities at startup time

2012-08-29T06:00:22+00:00

They all get set to the correct value when enabled. Signed-off-by: Keith Packard

altos: Expose a signed version of the tick count

2012-08-27T20:44:35+00:00

Useful when doing time comparisons. Signed-off-by: Keith Packard

altos: Provide interface for STM LCD driver.

2012-08-27T20:34:12+00:00

This provides a simple function interface for driving the LCD segments in the STM chip. It also uses the update complete interrupt to block LCD users during flush. Signed-off-by: Keith Packard

altos: Trigger sample complete when all data are ready

2012-08-26T16:53:16+00:00

This has each sensor mark a bit in the current data record which is then sent for processing when all of the data are present. Signed-off-by: Keith Packard

altos: Shrink STM stack size

2012-08-26T16:52:27+00:00

512 bytes should be enough for anybody. Signed-off-by: Keith Packard
