Hi everybody!
I found a huge problem! I need to read (in python) a DS18b20 (themperature sensor I2c) on a specific GPOI / 2g-IOT pin.
I did'nt found any example. I try to use some biblio from others boards without any sucess.
Any ideas!? Or sugestions!

I try to use Wiring PI, python-periphery, OpiIoTGPIO, DHT11-Python-library-Orange-PI,WiringPi-Python-OPNone of this works, or allow me to choose the pin that I want to assign to sensor.

Please advise!

DS18b20 is not i2c.
DS18b20 is 1 wire.
I think it's so hard to work on 2g-iot.
If you want to use i2c themperature sensor,
I'll recommend BMP085 or BMP280/BME280.
It's work on 2g-iot.
