VC ++ 6.0 serial communication
In vC ++ I am using MScomm for serial communication, I got the data in this format 02120812550006050.0, I don't get how to read it, what format it is in, starting the start of the frame and at the end of the file end, remaing, I don't know.
EDIT 1:
it contains date and data on how I can separate this
Funny characters are markers that indicate things like start of record, end of record, field separator, etc. Without knowing the actual protocol, this is a bit difficult to tell.
The data is much simpler.
Between marks 000f and 0002, you have a date / time field, Dec 2, 2008 12:55:00 PM.
Between marker 0002 and 0003 it looks like a simple float which could be dollar value or anytrhing really, it depends on what's on the other end of the link.
To separate it, I am assuming you read it into a variable character array. Just find the markers and extract the margins in between.
Date / time is a fixed size, and probably this value is also (since it has a leading 0), so you could just use memcpy to pull the information you want from the buffer, null terminate them, convert the value to float and voila ...
If it's a fixed format, you can use something like:
static void extract (char *buff, char *date, char *time, float *val) {
// format is "\x01\x0fDDMMYYhhmmss\x02vvvvvvv\x03\x04"
char temp[8];
memcpy (date, buff + 2, 6); date[6] = '\0';
memcpy (time, buff + 8, 6); time[6] = '\0';
memcpy (temp, buff + 15, 7); temp[7] = '\0';
*val = atof (temp);
}
and call it with:
char buff[26]; // must be pre-filled before calling extract()
char dt[8];
char tm[8];
float val;
extract (buffer, dt, tm, &val);
If not a fixed format, you just need to write code to determine the positions of the field separators and extract from them.
