设备初始化 InitDevice()

  • 配置中断优先级、使能中断 、配置时钟,关闭外设时钟,开启中断响应
    SystemInit()  
    -->DeviceConfiguration(TRUE, TRUE);//配置时钟,此处需要根据自己硬件设计来选择晶振  
    -->CKGEN_SOC->CLOCK_EN = 0xE0066;//关闭外围模块时钟  
    -->__enable_irq();开启中断响应
    
  • 设备识别
    SdkEvalIdentification()
    
  • 配置开启debug串口(IO配置,串口初始化)
    SdkEvalComIOConfig(SdkEvalComIOProcessInputData)
    
  • 初始化滴答定时器
    Clock_Init();  //此处与STM32类似有一个独立的滴答定时器,可以作为系统任务切换等使用非常便利  
    
  • 初始化外设
    SdkEvalLedInit(LED1);//初始化LED
    InitButton();//初始化按键
    SystemSleepCmd(ENABLE);//系统休眠开启
    

pwm初始化

  • 类似电源开关频率,通过pwm控制远远通断来改变light的明暗变化
    PWM_Init()  
    -->GPIO Configuration
    -->Configure GPIOs pin used to output PWM signal
    -->MFT Configuration  //多功能定时器初始化配置开启
    
    Appli_PWM_init();   初始化pwm状态
    

传感器初始化

LPS25HB_Init(& InitStructure);

检查设备地址是否合法

  /* Check for valid Board Address */
  if (!Appli_CheckBdMacAddr())
  {
#if !defined(DISABLE_TRACES)    
    printf("Bad BD_MAC ADDR!\r\n");
#endif
    /* LED Blinks if BDAddr is not appropriate */
    while (1)
    {
      Appli_LedBlink();
    }
  }

蓝牙协议栈初始化

BluenrgMesh_BleHardwareInitCallBack(&user_ble_cb);
/***&user_ble_cb***/
-->  Appli_BleStackInitCb,  //蓝牙协议栈初始化
-->  Appli_BleSetTxPowerCb, //蓝牙发射功率
-->  Appli_BleGattConnectionCompleteCb,  //非初始化,仅判断状态开启信号指示  
-->  Appli_BleGattDisconnectionCompleteCb,  //非初始化,仅判断状态开启信号指示  
-->  Appli_BleUnprovisionedIdentifyCb,
-->  Appli_BleSetUUIDCb,  //设置UUID,其中部分字节可以由用户定义,实现不同的功能  
-->  Appli_BleSetProductInfoCB,  //产品ID,公司ID,等自定义参数设置  
-->  Appli_BleSetNumberOfElementsCb,  //设置节点元素个数,default:3    
-->  Appli_BleDisableFilterCb  //使能,开启蓝牙监听捕获所有数据功能

蓝牙mesh参数初始化

BluenrgMesh_Init()  
  bdaddr,  //地址
  &TrParams,  //定义传输数据量10-65535
  &FnParams,  //与周围节点建立通讯的数量1-10
  &LpnParams, //低功耗节点的参数设置  
    LPN_RSSI_FACTOR_LEVEL, //用于判定提供最佳链路,
    LPN_RECIVE_WINDOW_FACTOR_LEVEL,  //用于确保由良好的接收路径
    LPN_MINIMUM_QUEUE_SIZE_LOG,  //最小数据包队列大小
    LPN_RECEIVE_DELAY,  //接收延时,默认150U
    LPN_POLL_TIMEOUT,  //发送超时,之前确认的良好通讯路径将失效  
    LPN_FRIEND_REQUEST_FREQUENCY, //请求间隔
    LPN_FRIEND_POLL_FREQUENCY,  //轮询周期,需要小于超时
    LPN_RECEIVE_WINDOW_SIZE,  //最大接收数据量
    LPN_SUBSCR_LIST_SIZE,  //最小成员列表1-5
    LPN_MINIMUM_RSSI,  //低功耗节点信号强度最小值-100  应尽量保证在-60   
    LPN_NO_OF_RETRIES, 重新尝试建立链接的次数 default:10
  MESH_FEATURES,
  &DynBufferParam  数据传冲空间

mesh mode初始化

-->BluenrgMesh_ModelsInit()
-->BluenrgMesh_SetVendorCbMap(&vendor_cb);

-->BluenrgMesh_SetModelGenericCbMap(&Model_Generic_cb);  //设置消息,请求,命令服务
-->BluenrgMesh_AddGenericModels(); //添加generic服务
