I am struggling with making things work. Particularly, not able to get any readings from this <LINK_TEXT text=“https://www.seeedstudio.com/Grove-Tempe … p-745.html”>https://www.seeedstudio.com/Grove-Temperature-%26amp%3B-Humidity-Sensor-（DHT11）-p-745.html</LINK_TEXT>.
Steps that I took:
- Attached sensor to port marked GPIO_115 which I reference as P9_27. Tried other ports/notations unsuccessfully.
- played with default Linux on board, updated, did not work either
- got latest Linux beaglebone 4.9.82-ti-r102 #1 SMP PREEMPT Thu Feb 22 01:16:12 UTC 2018 armv7l GNU/Linux
I attempted to get readings using these libs: bcm2835 1.55, beaglebone-dht, Adafruit_BBIO
Need help in debugging.
