From a507bb283782ee3adb1fc9ba0c6f094108ef558c Mon Sep 17 00:00:00 2001 From: Sebastian Leonhardt Date: Mon, 20 Jul 2015 01:50:26 +0200 Subject: YH8xx,YH9xx: Keymap improvement The main "innovation" in this patch are two "virtual buttons" for the record switch on YH92x targets. When the switch state changes, a single BUTTON_REC_SW_ON or .._OFF button event will be generated. Thus keymap code can react on switching, but not on the actual state of the switch. Wherever sensible, the following user scheme is applied: - use PLAY as confirm button - use REW button or Long REW to exit - use REC (YH820) or FFWD (YH92X) as modifier key for button combos Change-Id: Ic8d1db9cc6869daed8dda98990dfdf7f6fd5d5a1 --- firmware/target/arm/samsung/button-yh82x_yh92x.c | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) (limited to 'firmware/target/arm/samsung/button-yh82x_yh92x.c') diff --git a/firmware/target/arm/samsung/button-yh82x_yh92x.c b/firmware/target/arm/samsung/button-yh82x_yh92x.c index 2874a4a48a..ff8a580d2a 100644 --- a/firmware/target/arm/samsung/button-yh82x_yh92x.c +++ b/firmware/target/arm/samsung/button-yh82x_yh92x.c @@ -20,12 +20,15 @@ ****************************************************************************/ #include "system.h" +#include "kernel.h" #include "button.h" #include "backlight.h" #if defined(SAMSUNG_YH920) || defined(SAMSUNG_YH925) +#include "powermgmt.h" #include "adc.h" static int int_btn = BUTTON_NONE; +static unsigned int rec_switch; void button_init_device(void) { @@ -44,6 +47,9 @@ void button_init_device(void) /* remote PLAY */ GPIOD_ENABLE |= 0x02; GPIOD_OUTPUT_EN &= ~0x02; + + /* current record switch state */ + rec_switch = ~GPIOA_INPUT_VAL & 0x40; } /* Remote buttons */ @@ -117,7 +123,24 @@ int button_read_device(void) if (~GPIOA_INPUT_VAL & 0x08) btn |= BUTTON_DOWN; if (~GPIOA_INPUT_VAL & 0x02) btn |= BUTTON_FFWD; if (~GPIOA_INPUT_VAL & 0x80) btn |= BUTTON_REW; +#if defined(SAMSUNG_YH820) if (~GPIOA_INPUT_VAL & 0x40) btn |= BUTTON_REC; +#else + if ((~GPIOA_INPUT_VAL & 0x40) != rec_switch) + { + if (rec_switch) { + queue_post(&button_queue,BUTTON_REC_SW_OFF,0); + queue_post(&button_queue,BUTTON_REC_SW_OFF|BUTTON_REL,0); + } + else { + queue_post(&button_queue,BUTTON_REC_SW_ON,0); + queue_post(&button_queue,BUTTON_REC_SW_ON|BUTTON_REL,0); + } + rec_switch = ~GPIOA_INPUT_VAL & 0x40; + backlight_on(); + reset_poweroff_timer(); + } +#endif #if defined(SAMSUNG_YH820) if ( GPIOB_INPUT_VAL & 0x80) btn |= BUTTON_PLAY; #elif defined(SAMSUNG_YH920) || defined(SAMSUNG_YH925) -- cgit v1.2.3
