Does the NanoPi NEO support DHT22 temperature-humidity sensor connected via 1wire bus?
I use the DHT22 sensors on my Raspi2, they work fine.
Thank you.

Hello，
I just test DHT11 on NanoPi NEO ，but not DHT22，you can reference this link：http://wiki.friendlyarm.com/wiki/index.php/Matrix_-_Temperature_and_Humidity_Sensor . it works fine with NanoPi NEO.

Hi JJM,
I was following this wiki tutorial to try and get my sensor working but I get the following error:
root@neopi:/home/dietpi/sensor/matrix# matrix-temp_humidity
Hardware:Allwinnersun8iFamily
Revision:0000
BoardType:-1
FAHW-Lib: Fail to initPinGPIO
FAHW-Lib: Fail to initPwmGPIO
Fail to init board
I may have the PIN's wrong. Which pins did you use on the NanoPi Neo 1.4? If anyone else has come across this please let me know what I am doing wrong.
Thanks,
