Hello ,

I am simply trying to read serial data in the form of string and simply writing again in the form of string. Their is serial write data into string function but not for reading. How can I convert data into string. I have tried something by my own of which I am attaching the screenshot. Please guide me further.

Thanks

Hello Vikas, 

You should use convert byte array to string. to convert the data to string.  But wait for serial data & read it as it receives. 

Beware of memory management technique else u will ran out of memory.

Thanks for your reply . but as you can see in the screenshot I have already used byte array to string converter and I am simply taking analog data from pin A0 but in the output serial monitor I am just getting some random numbers which is positively not the reading of the sensor which is connected. Even if I try to  take the digital reading as true or false and changing it into 0 or 1 using comparison function "select" and converting it into string I am getting again random numbers.digital-read.pngImage Enlarger

Here is the vi...

from the serial monitor for getting analog data we need to send "Get_A00" similarly A02,A03... so on for other pins... and for digital "Get_D02" , D03,D04...D13

I am able to receive and send data through serial. But when I am getting correct data then why program runs default case always in the case structure.1.pngImage Enlarger2.pngImage Enlarger

I'm not sure how to best help you remotely as this will requires some debugging. I would start the debugging processing by trying to understand what the read VI is outputting from the serial communication. Maybe you will need to tweak some parameters based on what you are getting.
