...not yet tested.

The internal pull up / down resistors have a value of approximately 50KΩ on the Raspberry Pi.

For button & led's you can actually use any GPIO you want. Only the following 3 not ...

PIN | GPIO(BCM) | WiringPi | Name | Function
 8    |   14              |   15         |  TxD     | serial
10   |   15              |   16         |  RxD     | serial
 7    |     4              |     7         | 1-wire   | autoreset

....of course you have to adjust the variables in the script.

--------------------------------------------------------------------------------------------------------------------------------------------

The first sentence in my Github README.md says ...

"Just use ./install to install the Extender."    

.... and NOT  ' bash ./intall '  !!!

.... since everything is written in Python, you can of course also use 'python ./install' .

..... if './install' is started without 'sudo', the script asks for the root password and then restarts itself with root rights.

I have now retested the installation script and it starts on my system.

What I have done:

- download zip from github & extract it

- open a terminal

- change to folder ' fabscanpi-extender-master/fabscanpi-extender '

- Enter ' ./install ' & press Return

 

'sudo' in front of it is not necessary.

Alternatively, if that doesn't work for you, enter ' python ./intall ', then it should work.

 

Sincerely Helgetnt

I'm more the hardware guy....as sonn as I knew which GPIO to use, I finished the hardware ;)

Btw. if anymody else is interested in this: you can use any resistor from 1k to10k ohms as an pullup. There's no info on this on github ;)

okay, it's just a simple sudo python ./install

That ist correct. But you need some more Hardware (see GitHub page). Installing the Script is not enough.

You should open an issue on GitHub and ask the project owner.

I asume it's no shell script :D
So how do I start the installer? I assume it's a python script...
