全部註釋掉，因為它會對我們設定的按鍵產生干擾，具體情況我也不知道... 然後再在內模仿：   if (HAL_PUSH_BUTTON1())
  {
    keys |= HAL_KEY_SW_6;
  }
新增  ： if (HAL_PUSH_BUTTON8())   {     keys |= HAL_KEY_SW_8;   } 圖6：
------------------------------------------------------------------------------------------------------------- OnBard.c
將 void InitBoard( uint8 level )
{
  if ( level == OB_COLD )
  {
    // IAR does not zero-out this byte below the XSTACK.
    *(uint8 *)0x0 = 0;
    // Interrupts off
    osal_int_disable( INTS_ALL );
    // Check for Brown-Out reset
    ChkReset();
  }
  else  // !OB_COLD
  {
    /* Initialize Key stuff */
    HalKeyConfig(HAL_KEY_INTERRUPT_DISABLE, OnBoard_KeyCallback);//修改此處
  }
}
改為： HalKeyConfig(HAL_KEY_INTERRUPT_ENABLE, OnBoard_KeyCallback);
記得在任務初始化函式中加入 RegisterForKeys( GenericApp_TaskID );     //註冊按鍵事件
圖7：
最後再在Coordinator.c中的 uint16 GenericApp_ProcessEvent( uint8 task_id, uint16 events ) 新增事件及其處理函式 case KEY_CHANGE:           GenericApp_HandleKeys( ((keyChange_t *)MSGpkt)->state, ((keyChange_t *)MSGpkt)->keys ); 再在 static void GenericApp_HandleKeys( uint8 shift, uint8 keys ) {   zAddrType_t dstAddr;    if ( keys & HAL_KEY_SW_1 )     {     }     if ( keys & HAL_KEY_SW_2 )     {     }     if ( keys & HAL_KEY_SW_3 )     {     }     if ( keys & HAL_KEY_SW_4 )     {     }     if ( keys & HAL_KEY_SW_8 ) //新增自己的按鍵及其處理函式     {       HalLedSet(HAL_LED_1, HAL_LED_MODE_FLASH);     }   } 最後燒到開發板中即可，祝大家實驗成功。
