qcc512x-qcc302x-qcc303x earbud led使用说明

1.LED默认情况，默认工程是一个LED,(定义的宏 HAVE_1_LED)

如下截图 MED     Project     General    DEFS

同时也可以参考如下代码

#if defined(HAVE_1_LED)

/*! The number of LEDs led_manager will control. If one LED is configured,

    it will use appConfigLed0Pio(), if two LEDs are configured it will use

    appConfigLed0Pio() and appConfigLed1Pio() etc. */

#define appConfigNumberOfLeds()   (1)

/*! PIO to control LED0 */

#define appConfigLed0Pio()       CHIP_LED_0_PIO

/*! PIO to control LED1 (not used) */

#define appConfigLed1Pio()       (0)

/*! PIO to control LED2 (not used) */

#define appConfigLed2Pio()       (0)

#elif defined(HAVE_3_LEDS)

/* The number of LEDs led_manager will control. */

#define appConfigNumberOfLeds()   (3)

/*! PIO to control LED0 */

#define appConfigLed0Pio()       CHIP_LED_0_PIO

/*! PIO to control LED1 */

#define appConfigLed1Pio()       CHIP_LED_1_PIO

/*! PIO to control LED2 */

#define appConfigLed2Pio()       CHIP_LED_2_PIO

#else

#error LED config not correctly defined.

#endif

以及LED更新显示函数

/*! \brief Update LEDs

    This function is called to update the LEDs, it checks the current LED state and

    runs through the active filters modifying the LEDs state as specified by

    the filters.

*/

static void appLedUpdate(ledTaskData *theLed)

{

    int filter;

    uint16 led_state = theLed->led_state;

    const unsigned nleds = appConfigNumberOfLeds();

    /* Run LEDs through filters */

    for (filter = 0; filter < LED_NUM_FILTERS; filter++)

    {

        ledFilter filter_func = theLed->filter[filter];

        if (filter_func)

            led_state = filter_func(led_state);

    }

    /* Update LEDs */

    switch (nleds)

    {

        /* Jump then fall-through to set the correct number of LEDS */

#ifdef LED_USE_PIOS

        case 3: PioSet32Bank(LED_2_BANK, LED_2_PIO_MASK, led_state & 0x04 ? 0 : LED_2_PIO_MASK);

        case 2: PioSet32Bank(LED_1_BANK, LED_1_PIO_MASK, led_state & 0x02 ? 0 : LED_1_PIO_MASK);

        case 1: PioSet32Bank(LED_0_BANK, LED_0_PIO_MASK, led_state & 0x01 ? 0 : LED_0_PIO_MASK);

#else

        case 3: LedConfigure(2, LED_ENABLE, led_state & 0x04 ? 1 : 0);

        case 2: LedConfigure(1, LED_ENABLE, led_state & 0x02 ? 1 : 0);

        case 1: LedConfigure(0, LED_ENABLE, led_state & 0x01 ? 1 : 0);

#endif

        default: break;

    }

}

我们可以根据实际项目情况来定义使用几个LED针对的定义宏，

HAVE_3_LEDS 、HAVE_1_LED、也可以增加HAVE_2_LEDS和HAVE_0_LED然后做相对应的修改。

根据实际项目修改

#define LED_RED      (LED_0_STATE)

#define LED_GREEN   (LED_1_STATE)

#define LED_BLUE    (LED_2_STATE)

#define LED_WHITE   (LED_0_STATE | LED_1_STATE | LED_2_STATE)

#define LED_YELLOW   (LED_RED | LED_GREEN)

以及修改对应状态的ledPattern，可以参考现成的定义如

const ledPattern app_led_pattern_power_on[] =

{

    LED_LOCK,

    LED_ON(LED_RED),    LED_WAIT(100),

    LED_ON(LED_GREEN),   LED_WAIT(100),

    LED_ON(LED_BLUE),   LED_WAIT(100),

    LED_OFF(LED_RED),   LED_WAIT(100),

    LED_OFF(LED_GREEN), LED_WAIT(100),

    LED_OFF(LED_BLUE),   LED_WAIT(100),

    LED_UNLOCK,

    LED_END

};

此外qcc512x-qcc302x的LED可以按照之前的系列，使用LedConfigure 控制，也可以当作PIO来控制。
