https://devzone.nordicsemi.com/f/nordic-q-a/66091/nrf52840-as-spi-slave-using-52832-main-codeI tried using nrf52832(as slave) communicate with stm32, it successed . But when I changed nrf52832 to nrf52840 to do the same thing, it failed . I use the nRF5_SDK_15.0.0_a53641a ,I confirm that the pins have changed And use nRF5_SDK_15.0.0_a53641aen-USTelligent Community 13Fri, 18 Sep 2020 15:38:06 GMThttps://devzone.nordicsemi.com/thread/270377?ContentTypeID=1Fri, 18 Sep 2020 15:38:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fe7af4c0-9e64-4736-be11-7fc8c76e170chmw<p>I sent a private message for you&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/270333?ContentTypeID=1Fri, 18 Sep 2020 12:40:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:44e6a2ee-e7d5-429b-bc98-7397b6d603a7J&#248;rgen Holmefjord<p>Hi,</p> <p>This depends on the code you have used for the SPI slave peripheral. In general, the drivers should work for different boards/chips, as long as the correct variant is set in the project preprocessor symbols, etc. If you have written your own drivers, or are interfacing the registers directly, it may need some modifications.</p> <p>Can you share the project/code you are using?</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
