2019-04-22Fix #3566 use an hardware timer for software PWM stability (#3615)Brice Figureau
With my XD60, I noticed that when typing the backlight was flickering. The XD60 doesn't have the backlight wired to a hardware PWM pin. I assumed it was a timing issue in the matrix scan that made the PWM lit the LED a bit too longer. I verified it because the more keys that were pressed, the more lighting I observed. This patch makes the software PWM be called during CPU interruptions. It works almost like the hardware PWM, except instead of using the CPU waveform generation, the CPU will fire interruption when the LEDs need be turned on or off. Using the same timer system as for hardware PWM, when the counter will reach OCRxx (the current backlight level), an Output Compare match interrupt will be fired and we'll turn the LEDs off. When the counter reaches its maximum value, an overflow interrupt will be triggered in which we turn the LEDs on. This way we replicate the hardware backlight PWM duty cycle. This gives a better time stability of the PWM computation than pure software PWM, leading to a flicker free backlight. Since this is reusing the hardware PWM code, software PWM also supports backlight breathing. Note that if timer1 is used for audio, backlight will use timer3, and if timer3 is used for audio backlight will use timer1. If both timers are used for audio, then this feature is disabled and we revert to the matrix scan based PWM computation. Signed-off-by: Brice Figureau <brice@daysofwonder.com>
2019-01-28Backlight - New option : BACKLIGHT_CAPS_LOCK (#4769)Rockman18
* [BACKLIGHT_CAPS_LOCK_INDICATOR] Use backlight toggling as Caps Lock LED I've implemented this feature because S65-X doesn't have LED indicators and the existing led_set_kb(usb_led) function try to use backlight as indicator but that creates an inconsistency with backlight_config state. - define `BACKLIGHT_CAPS_LOCK_INDICATOR` to enable Caps Lock indicator using backlight (for keyboards without dedicated LED) - Don't turn off LED indicators when suspend because backlight is already turned off. Else led_set(0) will turn back on backlight. - Documentation has been updated * [BACKLIGHT_CAPS_LOCK_INDICATOR] Turn off all LED indicators except Caps Lock if BACKLIGHT_CAPS_LOCK_INDICATOR * [BACKLIGHT_CAPS_LOCK] Rename BACKLIGHT_CAPS_LOCK_INDICATOR * [BACKLIGHT_CAPS_LOCK] Use new IS_LED_ON method

2018-10-26Fix incorrect doctoring in feature.backlight.md (#4244)Phillip Tennen
I'm guessing someone deleted a row at some point in the past, but I didn't blame it.
