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

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!
