altos/stm: Make i2c code handle PCLK1 of 24MHz

2017-02-20T20:34:02+00:00

Just adds the necessary defines to the code. Signed-off-by: Keith Packard

altos/stm: Set i2c recv DMA to HIGH

2016-09-03T06:23:51+00:00

Make sure receive DMA is higher than any TX dma so that it always runs in preference. Signed-off-by: Keith Packard

altos: Replace ao_alarm/ao_clear_alarm with ao_sleep_for

2015-02-14T07:51:10+00:00

Having arbitrary alarms firing in the middle of complicated device logic makes no sense at all. Therefore only correct use of ao_alarm and ao_clear_alarm was around a specific ao_sleep call, with correct recovery in case the alarm fires. This patch replaces all uses of ao_alarm/ao_sleep/ao_clear_alarm with ao_sleep_for, a new function which takes the alarm timeout directly. A few cases which weren't simply calling ao_sleep have been reworked to pass the timeout value down to the place where sleep *is* being called, and having that code deal with the return correctly.

altos: Clean up STM I2C clock computations

2012-06-28T00:18:57+00:00

Fix both clock time and rise time. Signed-off-by: Keith Packard

altos: get MPU6000 I2C link working reliably

2012-06-27T21:38:35+00:00

This slows the i2c bus to 100kHz (yuck), sets the rise time to spec (it was way off) and adds more delays during bus setup. I've run this for hours now without trouble. Will try to adjust things back to fast mode and see if I can make that work as 100kHz isn't fast enough to reliably get data at 100 samples/sec. Signed-off-by: Keith Packard

altos: Wait for i2c START condition before setting interrupt bits

2012-06-27T09:46:27+00:00

This seems better than the random loop that it replaces, but I still have no idea why this is required; it doesn't coorespond to the docs at all... Signed-off-by: Keith Packard
