请问mt6755上如何配置双闪光灯
1.Porting sub driver
path: mediatek\custom\common\kernel\flashlight\src\sub_strobe.c
If flash driver has written for main flash, following is the steps to
change to sub flash driver.
-- change one word in the driver.
//leds_strobe.c, main led driver
……
MUINT32 constantFlashlightInit(PFLASHLIGHT_FUNCTION_STRUCT *pfFunc)
……
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
//sub_strobe.c, sub led driver
……
MUINT32 subStrobeInit(PFLASHLIGHT_FUNCTION_STRUCT *pfFunc)
……
-- remove
/* LED flash control for high current capture mode*/
ssize_t strobe_VDIrq(void)
{
return 0;
}
EXPORT_SYMBOL(strobe_VDIrq);
-- change file name to sub_strobe.c
2.Modified parameters file
–flash_tuning_custom_sub.cpp
–flash_tuning_custom_cct_sub.cpp
3.Enable sub flash
#define SUB_FLASH_SUPPORT 1思路应该是一样的

学习学习，就没见过55
你这个应该说的是前摄代闪光灯的吧
我问的是后摄两个闪光灯，双色温的

我知道双色温的意思，不过没有了解过，MT6755是否支持这个功能?
这个需要软件上的算法配合才行。
不是简单的拍照时两个LED同时亮一下就行的。
我现在就是配置成双闪的时候 摄像头就没图像了

估计是他们的算法的事。因为这个双色温的东西，需要算法后才会用LED去补偿。
