https://devzone.nordicsemi.com/f/nordic-q-a/20276/nrf24l01-spi-settingsDear sirs, I&#39;ve had a difficult time establishing communication between my nRF24L01+ board and the SPI bus on my Arduino Uno R3 microcontroller. Could you please provide me with a snippet of code that would read the status register? Also, I read elsewhereen-USTelligent Community 13Mon, 27 Mar 2017 12:53:32 GMThttps://devzone.nordicsemi.com/thread/78980?ContentTypeID=1Mon, 27 Mar 2017 12:53:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4e7a4eac-d712-4e43-ad5e-369fb3de584fovrebekk<p>Hi</p> <p>Have you tried one of the many nRF24L01+ Arduino drivers, such as <a href="https://github.com/nRF24/RF24">this one</a>?</p> <p>Reading the STATUS register is actually really simple, since the value of this register is returned on the first read byte, regardless of which SPI command you use.</p> <p>This means that if you just clock out 0x00 on the MISO line (command for reading the CONFIG register (reg 0) ) you should see 0x0E come back, which is the default value of STATUS. If you don&#39;t see any toggling on the MISO line it is usually a sign that the pins aren&#39;t wired up properly.</p> <p>I am a bit unsure what regulator issue you are referring to. As long as the regulator can deliver a stable current up to about 20mA you shouldn&#39;t have any issues. What speed are you running the SPI bus at? Do you have a scope available to monitor what&#39;s actually happening over the lines?</p> <p>Best regards<br /> Torbjørn</p><div style="clear:both;"></div>
