labview.vi

Hello everyone,

I am getting data from serial port RS232 through Labview with my laptop . baudrate is 38400 and there is about 4080 byte every 5 ms (transmission rate).

I am going to extract some specific bytes from each word (11 bytes in every word). I have to first convert the ASCII format of data to decimal and then extract some special bytes to get the waveform.

So far I have converted the ASCII string to byte array and then convert byte array to decimal by using type cast function without yet extracting those two desired bytes. (Because I didn't find the right function yet)

My question is that after getting data, when I am going to do conversions, program speed will decrease and it takes long time to do theses conversions after each transmission. I mean the waveform progress very slow.

I am thinking about using Mathscript after reading from serial port to increase speed and being able to do conversion. I have attached the program. I am wondering if you could let me know whether I am doing right.

Regards,

hello everybody,

I am trying to connect my device through serial port and then get the waveform real-time. I have written a program but the problem is that the graph is an straight line with zero amplitude that sometimes show up which is not desired one.Could you please somebody help me and check the attached vi. I really need your help. Thanks in advance.
