https://devzone.nordicsemi.com/f/nordic-q-a/2034/how-to-test-nrf24l01-with-pic1845k22Hello everyone! I have two sets of PIC18F45K22 and nRF24L01, one as a Tx, and another one as a Rx. I have programmed the PIC using mikroC compiler. My question is how do i check this SPI communication using oscilloscope? What data should i observeen-USTelligent Community 13Thu, 10 Apr 2014 12:55:59 GMThttps://devzone.nordicsemi.com/thread/8749?ContentTypeID=1Thu, 10 Apr 2014 12:55:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:07b4ec75-fcca-4d47-b983-2f326dc30150Asbj&#248;rn<p>You should connect the four pins of the SPI interface to your scope and make it trigger on one of the pins, CSN would probably be a good starting point. You should see traffic in similar to this: <a href="http://wiki.analog.com/_media/resources/tools-software/uc-drivers/pmod_ad4_signals.jpg">wiki.analog.com/.../pmod_ad4_signals.jpg</a> I just googled a picture of a scope screen shot of SPI traffic. You should see the byte values that you send with the firmware on your PIC.</p><div style="clear:both;"></div>
