https://devzone.nordicsemi.com/f/nordic-q-a/30457/spi-custom-bit-rate-frequencyHello.... Is there a way to configure the SPI peripheral(s) to run at a custom bit rate (frequency)?... For example: Run SPI at 3.4MHz.. or any other custom frequency that&#39;s different from the default ones that are defined in the Nordic SPI configurationen-USTelligent Community 13Tue, 13 Feb 2018 11:00:06 GMThttps://devzone.nordicsemi.com/thread/120693?ContentTypeID=1Tue, 13 Feb 2018 11:00:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:10e7574f-0bb1-4736-9c87-2bedee2ee0a5MartinBL<p>Hi,</p> <p>Changing to an arbitrary frequency isn&#39;t straightforward and you will have to rely&nbsp;on trial and error. Please see my answer here:&nbsp;<a href="https://devzone.nordicsemi.com/f/nordic-q-a/29834/nrf52832-twi-at-50-khz-smbus-compatibility/118538#118538">RE: NRF52832 TWI at 50 KHz (SMBus Compatibility)</a>.&nbsp;The issues regarding the frequency is the same for both TWI, SPI, and UART.</p><div style="clear:both;"></div>
