MATLAB and Simulink teams,
As of MATLAB R2022b the VEX support package now has drivers/blocks for the GPS sensor and the 3-wire expander. More information is in the documentation release notes.
If you need to use these sensors make sure you install MATLAB R2022b, and if you need to renew your free VEX license this is the link.
Cheers!
