check custom string received via Serial

[Vindhyachal.Takniki]

1 Have attached a labview program. 

2. Data received is in pic attached. Two lines are received at a time. 

i.e 

numRoute:0001 addr:40bc time:18d2b2 hops:01 seqno:0259 size:0020
0c2f 0c2e 0c2e 0c2f 0c2e 0014

3. Want that string received matched the data and if format matched then display it , get the info and wait for string.

4. How to match the string received as mentioned in 2?

It looks like you are already doing this.  Are you not getting the results you want?

But for parsing that second line, I would just use Spreadsheet String To Array with a format of "04x" to create your array of U32.

Currently what i am doing is receiveing one line at a time.

But in actual what happens is outside system send two lines at a time :

a) NumRoute:  line

b) data line 

Need to receive both together so that information of both are not mixed. Current VU has issue that sometimes when 2nd line received of first data set & then 1st line of second data set. Both get mixed.

Issue is both lines have enter at their end. How to reeive two data lines at once?

You need to read two lines: use two VISARead calls and the NL as termchar…

But you still know the order of those lines!?

When you receive the "2nd line" first then you know it belongs to the previous dataset…
