How to enable UART with STM32F413 via MATLAB Simulink?

[YFu.1]

Hi guys,

I'm working on UART with STM32F413 via MATLAB Simulink recently.

I've followed this tutorial: 《Getting Started with STMicroelectronics STM32 Processor Based Boards》 from MathWorks.

And I can already turn on LED via MATLAB Simulink. And next step is UART.

But I don't know which block to connect with these two:

and how to command STM32 via these two blocks.

Anyone has an idea or experience with Simulink UART? It will be great to answer with images.

Appreciate that!
