How to read Serial Data from Arduino using labview VISA?

[outaiba]

I have an Arduino Mega2560 card, I have a ultrasonic sensor, and I labview2011 software, I try to operate the sensor in the arduino serial port TX / RX, with supervision labview,
ultrasonic sensor: DYP ME007TX
arduino Mega2560
how?
thank you

This example reads an analog sensor and plot the value in a VI

thks M, but i have labview 2011,i cant't open your files, do you have a picture of programme in labview,

Hi.

I am practicing for the first time with the Arduino (Uno),trying to receive data from the analog 0 input.

I took a vi from one of the formers here in the topic (TempMon.vi) and made some changes to remove the concave to temperature section.

In the loop , I left basically with the VISA read-> FRAC to string-> Graph .

Now I see that the strings are not constant (I put a constant voltage). most of the time its the same but is can varies . 

In the Arduino program, the output looks OK e.g. constant.

Attached, my VI.

Any suggestions?

Thanks

So what are you asking?  Are you just asking for a review of your code?

thanks.  🙂

Nice example.  Well done.

I am trying to receive data from a microcontroller using RS485. I am using the NI USB to RS485 with 2 ports (http://sine.ni.com/nips/cds/view/p/lang/en/nid/14584). The port LED is flickering showing that data is being read, however I cannot see any data on the front panel indicator. I have tried your arduino solution to no avail. What could be the problem, please?

Hello,

I had same problem to measure the temperature from serial monitor of arduino on labview and i am using this vi but it read only first value and show it every time it wont change conntineously. please help me.

Thank you.

This article presents a procedure for reading the analog ports of Arduino UNO R3 board , on which a Joystick shield was installed. The analog data are related to the position of command and can be monitored from the front panel of our program , for which we use serial communication.
