If I invoke an MCP23017 input switch device in mega, can I use some channels as inputs and some as outputs?

Thanks,

Brian H.

Yes. Inputs need to be defined each as a task. Outputs do not.

Are the optional pull up resistors invoked by default on the mcp2317 lines configured as inputs?

Thanks again,
