altos: Share common LCO functions in ao_lco_bits.c

2018-07-03T08:00:15+00:00

Move common code out of ao_lco.c and ao_lco_v2.c into a shared file, ao_lco_bits.c. Update ao_lco.h to include shared functions. Signed-off-by: Keith Packard

altos/driver: Improve quadrature debouncing for mechanical encoders

2018-06-17T08:28:36+00:00

Track state of encoder better and only bump values when the full motion is detected (all four states). Signed-off-by: Keith Packard

Switch from GPLv2 to GPLv2+

altos: Use simpler debounce logic for buttons

2016-04-20T03:21:30+00:00

Instead of waiting for a while after the transition to decide if it has stuck, signal the event right away and then ignore other transitions for the debounce interval. This seems to work just as reliably, but has the benefit of eliminating button latency at press time. Signed-off-by: Keith Packard

altos: Add telelco v0.3 (v0.2 with cc1200 instead of cc1120)

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/telefire,telelco: Add HAS_RADIO_RATE to launch system software

2014-07-13T06:52:05+00:00

This lets us set the rate to a lower value to improve range. 9600 baud works great; 2400 baud makes the initial search take a long time. Signed-off-by: Keith Packard

altos/stm: Make stm applications depend on ao_boot.h

2014-05-21T08:43:12+00:00

This should make sure they get recompiled when boot stuff changes. Signed-off-by: Keith Packard

altos: Make quadrature debounce per-pin rather than per-device

2014-05-15T15:31:24+00:00

Debouncing per-pin means we don't lose transitions, which makes counting a lot more precise. Signed-off-by: Keith Packard

altos: Simplify quadrature tracking

2014-05-09T07:05:39+00:00

Set the timer to 200Hz for a 5ms debounce interval. Then, simply look for transitions ending in both bits in the encoder being off, which indicates the the encoder is resting in a detent. If bit '2' is turning off, the encoder was rotated clockwise, otherwise the encoder was rotated counter clockwise. This is a lot more reliable, although still not perfect. Signed-off-by: Keith Packard
