[Anna]

HI, Is there any code example to use the PCAL6416APW as gpio extender? Thanks

Hi Anna,

I am afraid that the only code for I2C I/O Expanders we have is for the Semtech SX1509BIULTRT, which is used in the Nordic Thingy:52 reference design, see this Infocenter page for the hardware description.

The code for the Semtech I/O expander can be found in the Thingy SDK, downloadable from this page.
