[参考译文] CC1310：将参数传递给 GPIO 中断(索引之外)

尊敬的 Max：

事实上、我最终找到了一种方法来做您描述的事情。

可以使用 GPIO_setUserArgg 和 GPIO_getUserArgg 方法。 下面是一个简短的示例：

volatile uint32_t GpioArgument1 = 0x12345678;
volatile uint32_t GpioArgument2 = 0x55555555;

/*
 *  ======== gpioButtonFxn0 ========
 *  Callback function for the GPIO interrupt on CONFIG_GPIO_BUTTON_0.
 *
 *  Note: GPIO interrupts are cleared prior to invoking callbacks.
 */
void gpioButtonFxn0(uint_least8_t index)
{
    volatile uint32_t number = (volatile uint32_t)GPIO_getUserArg(CONFIG_GPIO_BUTTON_0);
    /* Toggle an LED */
    GPIO_toggle(CONFIG_GPIO_LED_0);
}

/*
 *  ======== gpioButtonFxn1 ========
 *  Callback function for the GPIO interrupt on CONFIG_GPIO_BUTTON_1.
 *  This may not be used for all boards.
 *
 *  Note: GPIO interrupts are cleared prior to invoking callbacks.
 */
void gpioButtonFxn1(uint_least8_t index)
{
    volatile uint32_t number = (volatile uint32_t)GPIO_getUserArg(CONFIG_GPIO_BUTTON_1);

    /* Toggle an LED */
    GPIO_toggle(CONFIG_GPIO_LED_1);
}


//Somewhere in the code
GPIO_setUserArg(CONFIG_GPIO_BUTTON_0, (void *)GpioArgument1);
GPIO_setUserArg(CONFIG_GPIO_BUTTON_1, (void *)GpioArgument2);

但愿这有所帮助。

此致、

Arthur
