How to Fetch and Display Data from DHT22 Sensor on AVR32UC with Zephyr OS?

finally gushh😂 , I choked it, I enabled detailed logging, which revealed an I/O error. I then double-checked the GPIO configuration, verified d pin setup, and added a pull-up resistor. After increasing delays and adding debug prints in d driver code, I finally moved the sensor to a different GPIO pin. I think I'm making progress in this, the sensor is now successfully fetching and displaying data. see this
