nRF52840 SPI Simultaneous Connection

[ZAC]

Hi, from the nRF52840's datasheet: Up to 4x SPI masters/3x SPI slaves with EasyDMA. Is it possible to connect the nRF52840 as a slave with another microcontroller and simultaneously as a master with a sensor using SPI? If yes, could you please give me the recommended 8 pins for that? Thanks.

Hi,

Q1) Yes, you can be a slave and master at the same time. Just make sure to use two different instances of the SPI. For example SPIM0 and SPIS1.

Q2) You, can use any pins you like. The only recommendation we have is to not place high frequency signals, such as SPI signals, close to the antenna.
