What is this error?

I am trying to write humidity and temperature data from DHT22 to thingspeak channel. I installed Arduino support package and additional library for DHT (FYI: I haven't set myself any directory when I install the package & library)

Then I get the error message as below:

### Build procedure for model: 'dht22_iot_demo' aborted due to an error.

Error(s) encountered while building "dht22_iot_demo": ### Failed to generate all binary outputs.

Please advise how to resolve it.

This looks like an issue due to spaces in the file. I would recommend renaming the file.

When I downloaded, here is where the file is located by default:C:\Users\mgovinda\MATLAB\Collections\Arduino Additional Sensors Library (DHT, LPS331)\...

yours should also have the MATLAB\Collections\... portion.

I recommend you change that to: C:\Users\mgovinda\MATLAB\Collections\Arduino_Additional_Sensors_Library\...

This way the spaces are gone and everything should work as intended.
