Hello everyone,

i am trying to use this node as indicated but i cannot get it to work specifically MCP3424 (4ch).

The aim is to use Node Red as a Fixture testing Linux embedded system for electronic boards.  
Everything works for me but I wanted to try this node and I can't use it.

I tried to email the author Ocean but got no reply.

Anyone have a sample flow on how to use it?

Thank you in advance for the support
