I'm having trouble getting a port expander (MCP23017) connected over i2c to work and I'm not sure where things are breaking-down.
I'd like to start by confirming that I have all of the operating system/configuration bits in-place before diving into the hardware side of things.
What is the best way to check to make sure I have the right kernel/modules/etc. to make i2c work? I'm using Armbian and have the i2s tools for Debian installed.
Thanks!
