Raspberry Pi read GPIO signals in Simulink

Hi,

I wanted to read the signals coming from a DTH11 or DTH22 sensor, which is connected to my RasPi via GPIO. Do I have to install the sensor-library first to get plausible values in simulinks "GPIO read"?

Thanks, Christoph

nobody a idea?

Hey, DHT22 or DHT11 sensor signal is 40bits. Using just the GPIO Read block won't suffice. You can consider creating a Device Driver block in Simulink for the same. The following link will help you create Driver block: https://www.mathworks.com/help/supportpkg/raspberrypi/device-driver-blocks.html

Hope that helps!

Why using GPIO Read block won't work?
