基于GR551x_SDK_V1.6.10\projects\ble\ble_peripheral\ble_app_template_freertos 历程实现了一个GPIO中断，GPIO口 APP_IO_TYPE_AON 6，中断中发送消息队列死机，其它地方相同的发送消息队列正常，xQueueSendFromISR和xQueueSend都试过，代码如下：

#define BTN_PIN APP_IO_PIN_6

#define BTN_PIN_TYPE APP_IO_TYPE_AON

static void btn_int_pin_handler(app_gpiote_evt_t *p_evt)

{

BaseType_t xHigherPriorityTaskWoken = pdFALSE;

vbus_sch_data_t vbus_sch_data = {0};

switch(p_evt->type)

{

case BTN_PIN_TYPE:

vbus_sch_data.len = 0;

vbus_sch_data.evt = 1;

xQueueSendFromISR(vbusQueue, (void *)&vbus_sch_data, &xHigherPriorityTaskWoken);

portYIELD_FROM_ISR(xHigherPriorityTaskWoken);

break;

default:

break;

}

}

const app_gpiote_param_t param[] =

{

{BTN_PIN_TYPE, BTN_PIN, APP_IO_MODE_IT_FALLING, APP_IO_NOPULL, APP_IO_ENABLE_WAKEUP, btn_int_pin_handler},

};

app_gpiote_init(param, sizeof (param) / sizeof (app_gpiote_param_t));
