Hello everybody!

I want to use a Raspberry Pi 3B+ to control a biorreactor. I have some sensors, and they give me data in an URL (http://plaato.blynk.cc/auth_token/get/pin).

How can I make a call to thar URL in Simulink? I don´t want to use ThingSpeak, and I´m sure that Simulink could do this in a simple way. Could yo help me?

Hi Vinico,

From my understanding you want to read data from a URL in Simulink. For this purpose you can create a user defined function block for the same. Once having created that you can use the ‘webread’ function to use the API’s provided by the website.

For examples on how to use webread, refer to the MATLAB Documentation here.
