Hello, can you help me solve a problem in Simulink, please?

I need to read a ds18b20 temperature sensor, connected to Raspberry Pi 3 model B, using Simulink. Do you have any idea how can I do this?

I'm sorry for the moment I have the same problem, I found a solution please

Alright, so I have to install an Raspberry Pi Library, "OneWire" for DS18B20. Where can I find it? All examples are for Arduino.

hi Dan Maria, i have exactly the same problem, but i am working on a STM32-E407 board.

i still havent been able to solve the problem, the Arduino code should be possible to implement in the “s-function builder” block.

hopefully by now someone has solved it?

I'm having similar issues developing a MEX code to use in the S-Function builder. I keep using sample code from both the OneWire and DallasTemperature Arduino libraries as a basis, but I still keep getting errors in return, especially with how the code is structured. I have posted a recent question about using the "Legacy 1-Wire" Matlab Add-on and how to implement it into simulink.
