node-red-node-piface pre-reqs in readme wrong #735

Open colinl opened 3 years ago

colinl commented 3 years ago

The readme for node-red-node-piface has the following pre-reqs:

Device Tree must be turned off. To do this run

sudo raspi-config

then select the Advanced Options, then Device Tree, and finally select No and OK. You will then need to reboot.

It also requires the WiringPi gpio command to be installed in order to work. See the WiringPi site for details on how to do this. The short version is...

sudo apt-get install git-core
git clone git://git.drogon.net/wiringPi
cd wiringPi
git pull origin
./build

Unfortunately Device Tree appears to be no longer available in raspi-config and the git repository mentioned is not available. I don't know what the correct procedure is, or I would submit a PR, I found this trying to help someone on the forum.

Edit: possibly even more serious, I followed the link from the readme for how to install wiringpi and there found "WiringPi did once support the PiFace board but support for that is now very much out of date."

Yes - I think it would need a total re-write to use the python RPi.GPIO (like the gpio nodes) - or probably the official one would be best - http://www.piface.org.uk/guides/Install_PiFace_Software/First_steps_with_PiFace_Digital_Python/

Sadly I no longer have a PiFace board so am not in a position to be able to take on this task.
