multiple analog read serial communication arduino

[watha2]

Hello,

I'm working on a project and I'm new to Labview,

Can someone tell me how to read multiple analog Read on Labview in Serial communication with Arduino UNO?

I've tried it, but the data is somehow error.

I also attached my current vi and arduino code.

Please help me.

You'll have better luck at https://decibel.ni.com/content/groups/labview-interface-for-arduino where the hobbyists who use Arduino can be found

Thank you, I still haven't get the solution yet, but thanks for telling me.

Hi,

I will try to look into this the next few days, but what I see now is that you read bytes without knowing how many bytes there are available at the serial port.

Use the property node 'Bytes at serial port' to see how many bytes there are and read those bytes.

Hi,

From your Arduino project you are sending more then one value. But in you VI you do not analyse the incomming data to split up Voltage and Current.

I would suggest that you send a fixed string with voltgae data and current data so that you know in your VI how many bytes you should receive and how to split up the data.

reviewing the code embedded in the microcontroller Arduino, this good but repeatedly write port, for some time working on a similar project and the solution was to save the data ports in variables and then print to the port only once between each one identified data must place such as "#".

In the LabVIEW program must read the plot and do a search so that filtres data by data, received from the arduino

He spent a great deal of time last night spamming every single thread on these message boards related to Arduino.

You can see an example for reading multiple analog inputs

Are you dense or something?

There is already an answer marked as the solution.
