用X-Cube-Ble2实施Freertos 2

Question

我正在尝试使用X-Nucleo-BNRG2A1盾牌中的Freertos应用程序实现BLE任务。我在没有Freertos的情况下完成了BLE应用程序（X-Cube-Ble2软件包），并且运行良好。为了实现弗雷托斯，我一直在研究ble_heartratefreertos示例以供参考。看起来HCI_USER_EVT_PROC（）函数在BLE_HEARTRATEFREERTOS示例和X-Cube-Ble2默认示例中有所不同。 BLE_HEARTRATEFREERTOS HCI_USER_EVT_PROC（）具有以下注释：

/**

  * Up to release version v1.2.0, a while loop was implemented to read out events from the queue as long as

  * it is not empty. However, in a bare metal implementation, this leads to calling in a "blocking" mode

  * hci_user_evt_proc() as long as events are received without giving the opportunity to run other tasks

  * in the background.

  * From now, the events are reported one by one. When it is checked there is still an event pending in the queue,

  * a request to the user is made to call again hci_user_evt_proc().

  * This gives the opportunity to the application to run other background tasks between each event.

  */

此外，HCI_USER_EVT_PROC（）函数在HCIUSEREVETPROCESS（）任务中都在等待线程标志的HCIUSEREVTPROCESS（）任务中调用。该线程标志是从HCI_NOTIFY_ASYNCH_EVT回调函数调用的。看起来HCI_NOTIFY_ASYNCH_EVT功能也与X-Cube-Ble2软件包不同。仅供参考：

static void HciUserEvtProcess(void *argument)

{

 UNUSED(argument);

 

 for(;;)

 {

  osThreadFlagsWait( 1, osFlagsWaitAny, osWaitForever);

  hci_user_evt_proc( );

 }

}

 

void hci_notify_asynch_evt(void* pdata)

{

 UNUSED(pdata);

 osThreadFlagsSet( HciUserEvtProcessId, 1 );

 return;

}

我的问题是，随着库文件不同，我如何用X-Nucleo-Ble2软件包实现Freertos。我是否应该在具有相同优先级的其他任务的任务中包含HCI_USER_EVT_PROC（），以便不会阻止其他任务？还是我缺少更新？
