Hello
I am trying to integrate an external temperature and humidity sensor (DHT22) with RIOT OS on an STM32 board. I’ve followed the driver documentation and added the relevant configuration, but the sensor readings return zero values.
I’m using RIOT version X.X on an STM32 Nucleo board (model F401RE). The sensor is connected via GPIO with the required pull-up resistor. Included the driver in the Makefile
and configured the periph_conf.h
for the corresponding GPIO pin.
Running the sample application provided by the RIOT documentation doesn’t fetch valid sensor data. Only zero values are returned. I have checked Using a Digital Temperature Sensor with RIOT OS - Hackster.io Java guide for reference but still need advice .
Can anyone help debug this or suggest steps I might be missing? Any assistance would be appreciated!
Thank you !
