https://devzone.nordicsemi.com/f/nordic-q-a/12055/nrf51822-spi-with-an-oled-screen-helpHello, I have an NRF51822 beacon board and two small 0.96&quot; OLED displays (does not matter for me which one o use). One with GND, VDD, D0, D1, REST, D/C, CS and VCC pins and the other with GND, VDD, SCK, SDA, RES, DC and CS pins.

Maybe you could share a bit of your implementation if that is not a big problem? Would be very helpful :)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/45645?ContentTypeID=1Tue, 23 Feb 2016 18:30:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7de016c8-58c4-49a1-8297-3e6b381c1c1eKeton<p>weird, it just works for me using nRF51 sdk10. I&#39;ve had to modify draw routine because my display uses SSH1106 but otherwise there were no problems.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/45644?ContentTypeID=1Tue, 23 Feb 2016 17:44:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:09b9a303-e6fb-4a7a-92ea-37b8268bd564ExcellentMax<p>Yes, it is and SSD1306. The problem I found with the library you suggested was that it is written for NRF52 and I probably ran into some compatibility issues. Is there a way to use standard Nordic&#39;s libraries to make this work? I mean spi_master.h and nrf_drv_spi.h ?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/45643?ContentTypeID=1Mon, 22 Feb 2016 18:34:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d1daf936-02a8-4a32-be00-fa1b71f957a8Keton<p>Judging from pin names this is most likely SSD1306 based display. One of forum members has written <a href="https://github.com/monpetit/nrf52-spi-i2c-master-ssd1306">library</a> for it.</p><div style="clear:both;"></div>
