NVIDIA hardware GPIO pins

Is there any functionality in matlab or simulink to read/write GPIO pins on Nvidia hardware? (particularly jetson nano). I find it very strange that there is tons of documentation on deploying deep neural nets to the hardware, but I cannot find any information on something that seems so simple.

You can call python from MATLAB.
What you can call from the terminal is not a topic for a MATLAB forum. That said, python can be invoked from the terminal if necessary.

Hi Andrew,
We are bringing the GPIO read/write functionality in MATLAB and Simulink in our future release R2021b as a part of the support package MATLAB Coder Support Package for NVIDIA Jetson and NVIDIA DRIVE Platforms.

Hi Ramakrishna,
I installed the R2021b with the MATLAB Coder Support Package for NVIDIA Jetson and NVIDIA DRIVE Platforms.
But there are no GPIO-Blocks, the Basics Folder in the Library is empty.
Do you have an Idea why the Folder is empty?
Thank you,
Tim S.

Hi Tim,
Thanks for trying out the MATLAB Coder Support Package for NVIDIA Jetson and NVIDIA DRIVE Platforms. Can you please update the spkg if there are any updates?, we have added the GPIO blocks in the Basic library but somehow in the release version is not showing up. We have fixed this issue in the November monthly update 21.2.1. Hopefully this version must resolve this issue, otherwise, do the following
1. Please run this command in MATLAB
>> rehash toolboxcache;rehash path;
2. Right click “NVIDIA Jetson and NVIDIA DRIVE/Basic” and then select the Open Basic Library
Thanks,
Ramakrishna
