Hello all,
For my project at school i need to read an dht11 sensor with arduino and labview.
all the tutorials i watched are outdated and do now work for me.
could someoneplease tell me if LVFA is still working correctly with today's software or is it better to use linx software if so could somebody show me how?.
kind regards,

Hi pat,
I suggest you to download LINX using VIPM. Once done, you can go to Help>Find Example>Search "DHT11". I didn't try the example yet, but I hope it works

Hello tr_dane,
EDIT: FIXED BY REINSTALLING VIPM AND NI VISA
i tried downloading LINX but in the tutorial it says i need to load firmware into the arduino but getting an error, ill post the error log here.

Hi pat,
Did you try to load firmware to arduino by following method mentioned in https://www.labviewmakerhub.com/doku.php?id=learn:tutorials:libraries:linx:getting_started ?
Load Firmware
Ive manage to upload LINX firmware to my arduino uno and run the vi. but I don't have any DHT11 laying around to try it.

Hello,
thank you verry much for the help.
i got everything working and can run the blink example but the dht example is not working im getting error 5001 and i have looked up the error but it says that the digital input pin being read from does not exist on the specified board type but i tried using other pins and looked for an option to select the type of board?
im using the arduno mega
kind regards,

Hi Patrick,
I didn't have any DHT11, so I've tested the vi and got the Error 5001. Maybe you can check wiring and test the sensor using arduino program to check it's functionality and try again with LINX.
Im sorry, I can't help you more

thank you for the help i fixed by adding custom command to arduino
here is an link from the video that helped me fixing it if somebody is interested: https://www.youtube.com/watch?v=DGTbRQR-x_4
it is in some kind of stange language but you can just follow the video or read his tutorial in description.
