https://devzone.nordicsemi.com/f/nordic-q-a/8123/best-way-to-modify-examples-in-sdk-8-1Hello, I&#39;m getting started with SDK 8.0. The examples complied and flashed for me relatively painlessly on OSX, and the project organization is easy to understand. Now I am looking at modifying the HID keyboard example for a device that I am buildingen-USTelligent Community 13Mon, 13 Jul 2015 21:07:34 GMThttps://devzone.nordicsemi.com/thread/29159?ContentTypeID=1Mon, 13 Jul 2015 21:07:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4f556e3d-95d3-4bcc-94ed-c985096e1843405nm<p>That gives me enough to work on figuring out.

Please see the section on <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk51.v9.0.0/hardware_driver_gpiote.html?cp=4_1_0_2_1">GPIOTE in infocenter</a> for details.</p> <p>You will want to initialize your 12 buttons, and setup an event handler that manages interrupts on these. I&#39;m not really sure what you want in your last two paragraphs, but I think you will find the section on the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk51.v9.0.0/group__nrf__ppi.html?cp=4_1_0_6_6_23">programmable peripheral interconnect</a> module useful.</p> <p>Hopefully this answers your question. Best regards,</p> <p>Øyvind</p><div style="clear:both;"></div>
