* tests: make lighbar test easier to debugJett Rink2019-04-241-8/+10
| | | | | | | | | | | | | | | | | This test was failing and it is easier to comment out tests that are passing to debug. I needed to add a precondition so each test would pass on its own. I also needed to remove the static modifier to allow each test to be comment out.

* common: lightbar: Add histeresis to prevent flickeringGwendal Grignou2015-10-231-0/+49
| | | | | | | | | | | | | | | | | | | | | | | When ALS is enabled, if light is around one threshold (say 40 lux), the lightbar will flicker between readings. Add a histeresis to prevent the flickering. The current setting is: setting ^ (dim) 2 | ------+---->---+ 1 | +----<---+--->---+ (bright) 0 | +---<---+--------- +-------+--------+-------+--------> lux 20 40 60 BRANCH=smaug BUG=chrome-os-partner:44400 TEST=check in a dark room (30~40 lux) there is no flickering. Add unit test. Change-Id: I4018e2c2ed764abf9c9ed28e2d50a3e94a7d5f75 Signed-off-by: Gwendal Grignou <gwendal@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/308205
* Remove PULSE and TEST sequences from lightbar moduleVic Yang2014-10-081-57/+47
| | | | | | | | | | | | | | | PULSE and TEST sequences are not used anywhere. Remove them to save flash space. Also, fix msleep(MSEC) calls in the unit test; it's essentially usleep(SECOND) written in an incorrect way.

* lightbar: correctly revert to the S0/S3/S5 patternsBill Richardson2014-08-201-0/+294
This CL ensures that temporary "one-shot" sequences such as KONAMI, TEST, TAP, etc. will revert to the previous "normal" sequences even when interrupted by other one-shot sequences. This also adds a test for those cases.
