I have a question regarding the Simulink IO for Arduino model in Normal mode (Link). I wonder whether this feature will support the custom driver block? I know we can use s-function to access extra hardware resource on an Arduino Board in External Mode. However, if I am using the Normal mode with Simulink IO, is it possible to customize the IO server run on the Arduino board?
As an example, I want to implement the OneWire Protocol and read the temperature from a DS18B20 sensor. Since the OneWire block is not implemented in the Arduino support for Simulink package, I would like to create a block by myself with C++ codes. This block will work well in External mode where it run on the Arduino target. I wonder whether it is possible to run the model on my PC, but read the data from the hardware using Simulink IO function?
