Create custom simulink block from low-level C++

hi, I never created a block for simulink and before starting, since I saw that there are many ways to do it, I wanted to ask for some advice.

The block I want to implement is to use an I/O hardware interface

https://store.digilentinc.com/analog-discovery-2-100msps-usb-oscilloscope-logic-analyzer-and-variable-power-supply/

which is only supported in matlab parsially. What I wanted to do is create a simulink block to use it at 100%.

Hardware has its own SDK in C++, and I am very familiar with this programming language. So the simulink block should call low-level C++ functions.

what the simulink block should do is (all via C++ SDK):

1) initialize the device.

2) exchange data in real time with the outside world through the I/O hardware interface.

3) close the device

Can you recommend the best way to create this block, if there is any documentation you recommend reading or if there is a better way to do what I have described?

Thanks in advance,

Federico
