Preparing Data Structure for Data Capture

How to prepare data structure for capturing data from a machine?? Chaitanya

Can you be a bit more specific? Your question could be answered in a dozen different ways.

I would like to store the data from the sensor after intializing or sending all the commands to the sensor i,e for continous data output??

David Crow

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

Via Serial port(rs232)

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));
}
