Preparing Data Structure for Data Capture

[David Crow]

Does this "sensor" have an API? How is it connected to the computer?

Via Serial port(rs232)

[David Crow]

So just search CP articles for "serial." http://www.codeproject.com/system/serial.asp[^] http://www.codeproject.com/system/chaiyasit_t.asp[^] http://www.codeproject.com/internet/serialporttocommunicate.asp[^] http://www.codeproject.com/system/simpleserialcomm.asp[^] http://www.codeproject.com/system/cserialcom.asp[^] You can also Google for the same.

How to record/process data sent from the sensor????

[David Crow]

Having not coded very much serial stuff before, this is just a guess. Those other articles I referenced would have shown this, but I think you'll use something like:

HANDLE hPort = CreateFile("\\\\.\\COM1", ..., OPEN_EXISTING, ...);
ReadFile(hPort, ...);

Also see here.

am using Send() and Recieve() functions lnewlength = send(lnewSocket,(char*)lnewData,lDataLenght,0); lnewlength= recv(lnewSocket,(char*)lData,1024,0);

[David Crow]

Can those be used with serial communications, or are they for sockets only?

they are for sockets....

[David Crow]

Then why are you using them with a serial port?

Actually, if i would like to store the data of the "lData" parameter when lnewData[]={.....}(soem bytes) in storearray[], the how could i do? Is this correct?? if(lnewdata[8]==({..,..,..,..,..}) { BYTE storearray[1024]= lData; } can i work so with a string???

I doubt it.

What is lnewdata? Are you comparing or (supposed to be) assigning?

chaitanya22 wrote:

BYTE storearray[1024]= lData;

What is lData?

BYTE lnewData[8]={0x02, 0x00, 0x02, 0x00, 0x20, 0x24, 0x34,0x08} lnewlength= recv(lnewSocket,(char*)lData,1024,0); if(lnewData[8]=={0x02, 0x00, 0x02, 0x00, 0x20, 0x24, 0x34,0x08}) { BYTE storearray[1024]=lData; //i would like to store the array of recieved bytes in storearray[1024] } chaitu

What is this? Try:

BYTE compare[8] = {0x02, 0x00, 0x02, 0x00, 0x20, 0x24, 0x34,0x08};
if (memcmp(lnewData, compare, 8 * sizeof(BYTE)) == 0)
{
memcpy(storearray, lnewData, 8 * sizeof(BYTE));
}
