Possibility to invert input on IO port expanders (PCF,MCP)

[toffel969]

Hi

On the "normal"(GPIO) switch input, there is a check box to invert the value (0-->1, 1-->). This option is not available on the I2C expander switch input.

Would it be a big problem to implement that ? Do you see it as a useful feature?

Best regards

I don't know how much work it would be to implement in those switch options, but I agree all GPIO pins should at least be treated equal when it comes to options.
But I guess these extra pins should be usable as normal GPIO pins and be usable in all existing plugins.
And that will be a lot of work to do.

Hi TD-er

Thanks for your reply. I will try to work around using a custom built where I invert the state in the code time being. I am following the "GPIO" handling debate on github and will hang in for the general integration of the IO expanders.
