(C)我已經寫好連結電腦，誰可以教我寫rs-232讀資料跟送資料
[i=s] 本帖最後由 風箏惡魔 於 2009-5-2 11:20 編輯 [/i]這是關於ip-link 1220 晶片是8051，
我目前就寫到這樣可以連結，但是不知道怎麼讀和送資料

} 大大的用法比較偏向純C
不知道大大有沒有試用過
CreateFile的方式來開啟COM port呢
記得CreateFile之後只要對COM port
使用FileRead及FileWrite就可以讀寫了
剩下的就是事件流程的控制 [i=s] 本帖最後由 Andy95 於 2009-5-4 13:48 編輯 [/i]
Send Data

fprintf(stderr, "read from zigbee error!\n");
exit(1);
}
return (retCode = rBuf[5]*(2<<8) + rBuf[6]);
}
==================================================
Received Data
char* receive(FILE *ZigBee, char *theData)
{
int n, i;
while((n = fread(theData,1,104,ZigBee))==0);
for(i=0;i<104;i++)fprintf(stdout,"%2x\t",*(theData+i));fprintf(stdout,"\n");
return theData;
}
....
......
int main(int argc, char *argv[])
{
char theData[200];
ZigBeeInit(5,0,1,atoi(argv[1]),1);
送端送資料~~
if(sendTo(ZigBee, 0xffff, "12345") == 0){
fprintf(stdout, "I have sent it\n");
}
=========
收端收資料~~
fprintf(stdout, "Now ready to receive!\n");
if(theData == receive(ZigBee, theData)){
fprintf(stdout, "I have receice!\n");
}
system("PAUSE");
return 0;
}
各位大大~我寫這樣有錯嗎?
為什麼還是收不到資料>"<
我是用IP-LINK1220 zigbee~無線傳輸資料 這個部分我是建議你先做硬體上的測試看看是否正常
你可以先使用超級終端機測試看看硬體是否正確
再考慮程式碼的問題 [i=s] 本帖最後由 cmdunlop 於 2009-10-7 14:52 編輯 [/i]

[color=#0099cc]複製代碼[/color][/list]
[/td][/tr][/table]
以上是8051對RS232寫法
while(!RI);就是在讀取
*tmp = SBUF;讀取完成後寫入SBUF
以上是不完善的程式碼
但是也可以應付你所需要的
內容有些Bug
請自行處理
靠仔細看妳應該是電腦端的程式並非是8051的程式
抱歉～沒注意到～ 這是十幾年前的程式了,8051(Single chip)那頭你要設好速率(本例是 9600),
有問題建議你用示波器(單一觸發)勾勾看是哪一頭出問題.
