先再写一个 两块板之间的数据传输
我想写的是ZigBee的广播 组播 点对点播，但是他们都是建立在这个传输的之上，所以先学习这个吧 ，顺便我也在学习一下。
首先打开一个协议栈。ZStack-CC2530-2.3.0-1.4.0 \ Projects \ zstack \ Samples \ SampleApp \ CC2530DB 怕你们弄混了就把目录贴出来。
一、 首先配置一下串口 ：
1 先在SampleApp.c文件中添加串口头文件 #include "MT_UART.h"
2 然后在void SampleApp_Init( uint8 task_id )函数下添加以下内容。
void SampleApp_Init( uint8 task_id )
{
SampleApp_TaskID = task_id;
SampleApp_NwkState = DEV_INIT;
SampleApp_TransID = 0;
<span style="color:#cc6600;"> MT_UartInit();
MT_UartRegisterTaskID(task_id);//注册串口
HALUARTWrite(0,"Reset",sizeof("Reset"));//提示复位 协调器复位一下 就打印一次也是证明串口配置好得标志</span>
/*
然后go to 进去MT_UartInit()；函数
你会看到：
</pre><pre name="code" class="cpp">void MT_UartInit ()
{
halUARTCfg_t uartConfig;
/* Initialize APP ID */
App_TaskID = 0;
/* UART Configuration */
uartConfig.configured = TRUE;
uartConfig.baudRate =<span style="color:#33cc00;"> MT_UART_DEFAULT_BAUDRATE</span>;
uartConfig.flowControl = MT_UART_DEFAULT_OVERFLOW;
uartConfig.flowControlThreshold = MT_UART_DEFAULT_THRESHOLD;
uartConfig.rx.maxBufSize = MT_UART_DEFAULT_MAX_RX_BUFF;
uartConfig.tx.maxBufSize = MT_UART_DEFAULT_MAX_TX_BUFF;
uartConfig.idleTimeout = MT_UART_DEFAULT_IDLE_TIMEOUT;
uartConfig.intEnable = TRUE;
#if defined (ZTOOL_P1) || defined (ZTOOL_P2)
uartConfig.callBackFunc = MT_UartProcessZToolData;
#elif defined (ZAPP_P1) || defined (ZAPP_P2)
uartConfig.callBackFunc = MT_UartProcessZAppData;
#else
uartConfig.callBackFunc = NULL;
</pre><pre name="code" class="cpp">*/
然后 go to 到上边绿色的的值
</pre><pre name="code" class="cpp">会看到
#if !defined( MT_UART_DEFAULT_OVERFLOW ) #define MT_UART_DEFAULT_OVERFLOW TRUE <span style="color:#ff0000;">//如果你用的是 两线的串口DDL 那么就需要修改成 FALSE</span><div class="client_siderbar_list_item"> </div> #endif #if !defined MT_UART_DEFAULT_BAUDRATE #define MT_UART_DEFAULT_BAUDRATE <span style="color:#ff6666;"> HAL_UART_BR_38400 </span><span style="color:#cc0000;"> //这一句就是波特率值 默认 38400 我们改成 115200</span> #endif #define MT_UART_DEFAULT_THRESHOLD MT_UART_THRESHOLD #define MT_UART_DEFAULT_MAX_RX_BUFF MT_UART_RX_BUFF_MAX #if !defined( MT_UART_DEFAULT_MAX_TX_BUFF )
}
到这步我们的串口配置完了。如果烧到板子中 复位 就会打印Reset
打印出来的是不是乱码了！！！！！！！！！！！！！
进行一下配置
结果：

接下来才是正事。
二 .Dat for Receive And Send
回到SampleApp.c文件
先看看uint16 SampleApp_ProcessEvent( uint8 task_id, uint16 events )函数
uint16 SampleApp_ProcessEvent( uint8 task_id, uint16 events )
{
afIncomingMSGPacket_t *MSGpkt;
(void)task_id; // Intentionally unreferenced parameter
if ( events & SYS_EVENT_MSG )
{
MSGpkt = (afIncomingMSGPacket_t *)osal_msg_receive( SampleApp_TaskID );
while ( MSGpkt )
{
switch ( MSGpkt->hdr.event )
{
// Received when a key is pressed
case KEY_CHANGE:
SampleApp_HandleKeys( ((keyChange_t *)MSGpkt)->state, ((keyChange_t *)MSGpkt)->keys );
break;
// Received when a messages is received (OTA) for this endpoint
case AF_INCOMING_MSG_CMD:
SampleApp_MessageMSGCB( MSGpkt );<span style="color:#ff0000;">//这是接收到的数据包处理函数 go to 进去</span>
/* <span style="color:#009900;"> void SampleApp_MessageMSGCB( </span><span style="color:#993399;">afIncomingMSGPacket_t</span><span style="color:#ff6666;"> </span><span style="color:#009900;">*pkt ) </span><span style="color:#993399;">//我们的数据都在这里面 可以 go to</span>

</span><span style="color:#009900;"> {
uint16 flashTime;
switch ( pkt->clusterId )
{
case SAMPLEAPP_PERIODIC_CLUSTERID:</span><span style="color:#ff0000;">//发送定义的数据包ID #define SAMPLEAPP_PERIODIC_CLUSTERID 1</span>
<span style="color: rgb(51, 204, 0); white-space: pre;"> </span><span style="color:#ff0000;">//添加 HalUARTWrite(0,"I get data",sizeof("<span style="font-family: Arial, Helvetica, sans-serif;">I get data</span>"));//提示收到数据</span><span style="color:#33cc00;">
</span><span style="color:#009900;"> break;
case SAMPLEAPP_FLASH_CLUSTERID:
flashTime = BUILD_UINT16(pkt->cmd.Data[1], pkt->cmd.Data[2] );
HalLedBlink( HAL_LED_4, 4, 50, (flashTime / 4) );
break;
}
}
*/</span>
break;
// Received whenever the device changes state in the network
case ZDO_STATE_CHANGE:
SampleApp_NwkState = (devStates_t)(MSGpkt->hdr.status);
if ( (SampleApp_NwkState == DEV_ZB_COORD)
|| (SampleApp_NwkState == DEV_ROUTER)
|| (SampleApp_NwkState == DEV_END_DEVICE) )
{
// Start sending the periodic message in a regular interval. <span style="color:#ff0000;"> //下面的的三个参数决定发送数据的周期命脉</span>
osal_start_timerEx(<span style="color:#ff6666;"> SampleApp_TaskID, </span><span style="color:#ff0000;">//它就是任务ID 函数开头定义了 SampleAPP初始化任务ID</span><span style="color:#ff6666;">
SAMPLEAPP_SEND_PERIODIC_MSG_EVT, </span><span style="color:#ff0000;"> //他在SampleApp.h文件中 #define SAMPLEAPP_SEND_PERIODIC_MSG_EVT 0x0001</span><span style="color:#ff6666;">

}
else
{
// Device is no longer in the network
}
break;
default:
break;
}
// Release the memory
osal_msg_deallocate( (uint8 *)MSGpkt );
// Next - if one is available
MSGpkt = (afIncomingMSGPacket_t *)osal_msg_receive( SampleApp_TaskID );
}
// return unprocessed events
return (events ^ SYS_EVENT_MSG);
}

// return unprocessed events
return (events ^ SAMPLEAPP_SEND_PERIODIC_MSG_EVT);
}
// Discard unknown events
return 0;
}
好了 大部分代码 写完了 接着就是 写个函数将 语句读出来
找到下边 这个函数 就是 读出 信息的函数了 我们做一些 修改 。
void SampleApp_MessageMSGCB( afIncomingMSGPacket_t *pkt )
{
uint16 flashTime;
switch ( pkt->clusterId )
{
case SAMPLEAPP_PERIODIC_CLUSTERID:
<span style="white-space:pre"> </span>HalUARTWrite(0,"I get data",sizeof(<span style="font-family: Arial, Helvetica, sans-serif;">"I get data"</span>));<span style="color:#ff0000;">//提示收到数据</span>
<span style="white-space:pre"> </span>HalUARTWrite(0,&pkt->cmd.Data[0],10);<span style="color:#ff0000;">//指针打印数据</span>
<span style="white-space:pre"> </span>HalUARTWrite(0,"\n",1);<span style="color:#ff0000;">//换行</span>
break;
case SAMPLEAPP_FLASH_CLUSTERID:
flashTime = BUILD_UINT16(pkt->cmd.Data[1], pkt->cmd.Data[2] );
HalLedBlink( HAL_LED_4, 4, 50, (flashTime / 4) );
break;
}
}
然后进行烧写 需要注意是
实验结果

后面写的 广播 组播 点对点 都是依托此实训 写的 。
