From df251d7a1387390383f12b3ff31d71d7e3de5a42 Mon Sep 17 00:00:00 2001 From: Rockman18 Date: Tue, 29 Jan 2019 01:57:56 +0100 Subject: Backlight - New option : BACKLIGHT_CAPS_LOCK (#4769) * [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 --- quantum/quantum.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'quantum/quantum.c') diff --git a/quantum/quantum.c b/quantum/quantum.c index 5d8ffe34e..c1829c768 100644 --- a/quantum/quantum.c +++ b/quantum/quantum.c @@ -1448,6 +1448,24 @@ void led_set(uint8_t usb_led) // PORTE &= ~(1<<6); // } +#if defined(BACKLIGHT_CAPS_LOCK) && defined(BACKLIGHT_ENABLE) + // Use backlight as Caps Lock indicator + uint8_t bl_toggle_lvl = 0; + + if (IS_LED_ON(usb_led, USB_LED_CAPS_LOCK) && !backlight_config.enable) { + // Turning Caps Lock ON and backlight is disabled in config + // Toggling backlight to the brightest level + bl_toggle_lvl = BACKLIGHT_LEVELS; + } else if (IS_LED_OFF(usb_led, USB_LED_CAPS_LOCK) && backlight_config.enable) { + // Turning Caps Lock OFF and backlight is enabled in config + // Toggling backlight and restoring config level + bl_toggle_lvl = backlight_config.level; + } + + // Set level without modify backlight_config to keep ability to restore state + backlight_set(bl_toggle_lvl); +#endif + led_set_kb(usb_led); } -- cgit v1.2.3-24-g4f1b
