nRF9160 DK I/O expander

[Francis S]

The nRF9160 DK has an I/O expander that can optionally be used to interface the LEDs, slide switches, and buttons.

Any sample code available on how to interface to the I/O expander.

@helsing any update on getting the nRF52840 to work? Earlier today I was trying to get connected to the nRF52840 with an app figuring that was how Nordic had setup the control of the external memory and I/O but I couldn't find the nRF52840 and there is nothing about access the I/O or memory other then it exist.

Hi Kevin,

I am not sure what exactly you are asking for. Perhaps you could create a new case and give a little background information, explaining what you would like to achieve?

Best regards,

Håkon
