Lectura del puerto serial e impresion de datos

Wire the ascii code for a comma into the termination character input of the Serial Configure.  Decimal 44 or hex 2C.

But it would be more logical to program it to send a linefeed character which is ASCII code decimal 10 or hex 0A.  The serial configure already defaults to linefeed as the termination character.

Can you help me with an example? I got the idea about Arduino, but I'm new to using LabView, I owe you one for help me, thanks

How can I wire the Property Node to just accetp the data that come from write "L" for example?

I have no idea what you mean by this question.

Attached is a much simpler VI that will work.  You just need to program your Arduino to send the LF character at the end of every message it sends out.

[cesarjr.1991]

Really thanks! It works, but just for 10 seconds 😕 after that I have this problem.

[RavensFan]

Did you change the code in your Arduino?  That message tells me you hadn't received the termination character.

A slightly better version of the VI that takes care of some missing wires and indicators.

No my friend, I don't know what I have to change, and What is the mean of this " 100" in write block, this is my Arduino code, What I have to change?

Really thanks for everything man, really thanks! 

[RavensFan]

You need to right the linefeed character wherever you send a response.

If you wrote the Arduino code, then YOU should know how to do it.  I don't do C code.

In basic it would be something like print#1, chr$(10)

[cesarjr.1991]

Thanks man for everything, i'll try it, realyy thanks I never see this code works like this! Thank you so much! 😄 And excuse me that I don't understand some directions, I don't understand English very well, but i'm doing it, Thank you again man.
