https://devzone.nordicsemi.com/f/nordic-q-a/5321/nrf24l01-pic16f886-and-raspberry-piIm using the Raspberry Pi as my transmitter and PIC16F886 as my receiver. For the RasPi im using the library from TMRh20 and on the PIC side using code I got from various sources. I have the PIC side working (using one PIC as TX and two PICs as RXs anden-USTelligent Community 13Mon, 02 Feb 2015 08:51:05 GMThttps://devzone.nordicsemi.com/thread/18604?ContentTypeID=1Mon, 02 Feb 2015 08:51:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3ccfff9c-ad91-4637-b68d-5a76e0b15593Asbj&#248;rn<p>I&#39;m not sure I get what&#39;s wrong and what&#39;s not working. I would recommend you to try to narrow down what is working and what is not working. For example, on the transmitter side, check the VDD_PA pin. This pin will go up to 1.8 V when it&#39;s transmitting, so for the transmitter it should regularly go up to 1.8 V. It&#39;s a simple way to check that the transmitter at least is sending something.</p> <p>On the receiver, do you get any interrupts? Which ones? Do you see any 1.8 V on the VDD_PA pin on the receiver? This pin will go high when sending back the ACK.</p><div style="clear:both;"></div>
