Hello. I have just started to evaluate Cayenne, and so far I am impressed with what I see.
I have run into one issue (of my own doing) that I have not been able to rectify. I am using a B+ with two MCP23017’s to extend my I/O count by 32 GPIO. I inadvertently added two extensions for the same base address of 0x20, and one for base address 0x21. So, when I pull down the extensions from the banner, I get three instances of “MCP23017”, when I really should have two. What do I need to do to delete an unwanted extension?
