Sofle键盘QMK RGB层单侧点亮异常求助

问题现象 #

启用RGBLIGHT_LAYERS_OVERRIDE_RGB_OFF后，当RGB处于全局关闭状态时，触发层按键仅USB连接的主设备侧RGB点亮，从设备侧保持关闭；但RGB开启状态下，层触发时两侧RGB颜色可正常同步。

当前配置 #

config.h中RGBLIGHT相关配置 #

#ifdef RGBLIGHT_ENABLE
    #define RGBLIGHT_SLEEP /* If defined, the RGB lighting will be switched off when the host goes to sleep */
    #define RGBLIGHT_LAYERS
    #define RGBLIGHT_MAX_LAYERS 4
    #define RGBLIGHT_LAYERS_OVERRIDE_RGB_OFF
    #define RGBLIGHT_LAYERS_RETAIN_VAL
    #define RGB_DI_PIN D3
    #define RGBLED_NUM 72
    #define RGBLIGHT_LIMIT_VAL 150
    #define RGB_SPLIT {36,36}
    #define SPLIT_TRANSPORT_MIRROR
    #define RGBLIGHT_SPLIT
    #define RGBLIGHT_EFFECT_RGB_TEST
    #define RGBLIGHT_DEFAULT_HUE 180
    #define RGBLIGHT_HUE_STEP 10
    #define RGBLIGHT_SAT_STEP 10
    #define RGBLIGHT_VAL_STEP 10
#endif

解决步骤 #

1. 在config.h的RGBLIGHT_ENABLE代码块中添加层状态同步定义：

   #define SPLIT_LAYER_STATE_ENABLE
   

   该定义会强制主设备将当前激活的层状态同步到从设备，确保从设备能感知到层触发事件，进而执行RGBLIGHT_LAYERS_OVERRIDE_RGB_OFF的强制点亮逻辑。

2. 重新编译固件，分别刷入主、从设备两侧。

3. 测试验证：关闭RGB后触发层按键，两侧RGB应同步点亮对应层的颜色。

补充说明 #

问题根源在于RGB全局关闭时，从设备未收到主设备的层激活信号，导致无法触发RGBLIGHT_LAYERS_OVERRIDE_RGB_OFF的灯光逻辑。添加层状态同步定义后，主从设备的层状态保持一致，从设备会根据层状态和RGB配置自动响应灯光效果。
