Thanks for the reply
I have searched the internet and can find lots of examples using different packages, but they have one thing in common, the temp sensor is connected using the 1-wire implementation on the GPIO (4) pin.
I have the temp sensor attached to the i2c interface via the board. in my original post.
The link provided also shows a directly connected implementation.
I have also tried several of the packages on NPM and cannot get them to install properly, they fail when compiling.
I have RASPI-I2C package installed correctly and using the example code on the NPM site I am able to read the first byte of the sensor at address 1B on the i2c bus but I am not clear on how I can read the temperature from this.
If someone could point me in the correct direction from here I would appreciate it. In the meantime I will keep searching the net for examples.
