https://devzone.nordicsemi.com/f/nordic-q-a/29540/development-of-non-arduino-based-applicationsHi. I&#39;m new to both the nRF24L01+ and to this forum. I&#39;m intrigued by the prospect of using these amazing little transceivers as RF modems. Because I find elements of the device&#39;s datasheet to be difficult to understand, I&#39;ve been looking for tutorialsen-USTelligent Community 13Fri, 19 Jan 2018 08:26:31 GMThttps://devzone.nordicsemi.com/thread/117443?ContentTypeID=1Fri, 19 Jan 2018 08:26:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:df060c9c-2184-4a15-8d36-7fa828e65a43ovrebekk<p>Hi</p> <p>Welcome to the forum :)</p> <p>I would start by taking a look at the good old <a href="https://www.nordicsemi.com/eng/nordic/download_resource/10634/11/42758036/1486">nAN24-12 application note</a>.</p> <p>This includes a pdf describing the various ShockBurst modes in the radio, and a code example (based on an ST 8051 MCU) showing how to use the nRF24L01+.</p> <p>The appnote assumes that you have the nRF24L01(+) development kit, but I think it is still valuable even if you don&#39;t have it.</p> <p>Once you have read the PDF you can try to port the software examples to your MCU. The most important file is hal_nrf_l01.c, which provides a low level abstraction of the various configuration registers in the nRF24L01+.<br /> You also need to provide an implementation of hal_nrf_xxx_hw.c, which is the SPI abstraction layer that you need to implement specifically for your SPI hardware.</p> <p>The radio_xx.c and application_xx.c files show you how you can use the low level HAL to access the radio and send/receive data.</p> <p>Best regards<br /> Torbjørn Øvrebekk</p><div style="clear:both;"></div>
