w1temp and wiringPi

@kolarcz can w1temp co-exist with wiringPi or does wiringPi need to be removed / disabled?

The pin references in your example, what are they:

  1. BCM references
  2. wiringPi references
  3. Physical pin references
  4. Official GPIO references
  5. Some other references

At the moment when I run yor example with:

sudo node example.js

I have disabled the power pin in the js and I haven't done the modprobe or config.txt edit as I thought it could all be done with sudo.

I will keep trying.

All working fine with the GPIO references being from the BCM table.

Thanks, maybe I should write which reference I am using.

can you help? I can not get temp display on the blynk app?

I have used:
cat /sys/bus/w1/devices/28-041692d33eff/w1_slave | sed -n 's/^.(t=[^ ]).*/\1/p' | sed 's/t=//' | awk '{x=$1}END{print(x/1000)}'

which shows the current temp so I know the sensor is good, and Ive also installed w1temp library.

Im very new to this but understand basic python and java coding.
