Hi I'm trying to use the GP button on the hat. It's pretty undocumented. I thought it was SW1 on the diagram, but if so it should connect to GPIO 13 (pin 33) but it doesn't.
Any ideas how to use?
Hi I purchased one of these cads to link it to OpenPLC as suggested in the web site. Is there a specific library to allow this to be used with the OpenPLC editor?
thanks Dominic
