I want waveforms to be as Below: which driver I suppose to use is it SPI or SPIM? I tested out both that drivers I am unable to figure out how toen-USTelligent Community 13Mon, 26 Nov 2018 14:27:27 GMThttps://devzone.nordicsemi.com/thread/159062?ContentTypeID=1Mon, 26 Nov 2018 14:27:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7a69d3cf-96e8-4142-9127-6f8b6625a91dSusheel Nuguru<p>Hi Rohit,</p> <p>SPIM is with EasyDMA which is useful if you want to send/receive more than one byte at a time in your single transfer.</p> <p></p> [quote user=""]can you please share me <strong>APIs with configurations</strong> which can meet above diagram.[/quote] <p>&nbsp;The API for this is documented <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.2.0%2Fgroup__nrfx__spim.html">here</a>, I think you asking which <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.2.0%2Fgroup__nrf__spim__hal.html&amp;anchor=gaf6ad2321f2fd4a896c097b5d4040ff94">mode&nbsp;</a>will match your waveform.I cannot make much sense in your diagram without knowing the timing acronyms.&nbsp;</p> <p>&nbsp;</p> [quote user=""]please share the waveforms capture by you to meet above requirement.[/quote] <p>Are you asking us to implement the application to match the waveform for you? Sorry, I cannot help you there as that would consume a lot of time. Please read the API documentation and try it out yourself.
