What is the difference between pin 20 and pin 38? OneWire connection works if I use pin 20 (I2C). When I configure OneWire to use pin 38 and move the same connector to GPIO-D, no sensors are found. The same OneWire-DS18b20 connection is used in both…

I have already done that (using IO38 on GPIO-D connector)! it doesn't work. Do not find any sensors.

I do have pullup (4.7K) resistor between DQ and 3.3 V. I cannot have any values from OneWire devices if I am using pin38 GPIO-D connector. If I am using pin20 as OneWire (I2C connector) I get correct values (but touch do not work of course). It seem…

I succeed with OneWire bus using IO 10 but the problem is that I lose touch (i2c) capability what I need in my case. OneWire using Pin 38 seems to be unavailable. Is there any ideas how to solve this problem?
