Hi,

I've been trying to access the Raspberry Pi using MATLAB. At one point in the tutorials it asks for doing

targetObject = targetHardware('Raspberry Pi')

However, despite the Support Package being installed, it says "unrecognized function". I've reinstalled the package to no avail. In MATLAB online it works as expected. The documentation in help targetHardware is shown correctly as well.

Hi thanks for the reply. I am indeed using a Raspberry Pi 4 Model B running 32-bit OS Debian 'bullseye'.

I was running the command on the command window, no additional error lines or logs other than the Unrecognized function red text.

Thanks,

Hi @Javi

Since you mentioned that the command works correctly in MATLAB Online, the issue is likely related to your local MATLAB environment. I recommend checking out the following MATLAB Answers thread, which outlines several possible causes for the "Unrecognized function" error and how to resolve them:

Hope this helps!
