When I compile my sketch, I get the error message below.
It doesn't stop the sketch compiling and doesn't seem to cause any problem with it executing.
Whilst I don't fully understand the error, I'm guessing there is something going on between the SX1509_IO_Expander library and the I2C wire.h library. (As far as I can tell, both are up to date.)
This has only started happening since I switched from a Nano to a NanoEvery and from IDEv1to IDEv2 (which I did at the same time).
Is it something I need to worry about? If it is, how do I resolve it, and if not, why not?
