I want to implement spi communication and TWI communication on 2 IO pins.https://devzone.nordicsemi.com/f/nordic-q-a/77112/i-want-to-implement-spi-communication-and-twi-communication-on-2-io-pinsI am developing a NRF52810 product, I am downloading using JTAK on NRF52832 development board. I have the NRF52810 because of the lack of IO pins. SPI CLK , TWI CLK are pin P0.12, SPI MOSI, TWI Data is pin P0.15, I want to control the SPI CS pin withen-USTelligent Community 13Mon, 05 Jul 2021 13:46:01 GMTRE: I want to implement spi communication and TWI communication on 2 IO pins.https://devzone.nordicsemi.com/thread/318662?ContentTypeID=1Mon, 05 Jul 2021 13:46:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:92a1ee04-95cb-4ec7-99bf-a4ffa02a140dDmitry<p>Hi.</p> <p>from nRF side, you can configure both modules (nrfx_twim and nrfx_swim) at same pins, and switch between them, just don&#39;t forget to call uninit() of one module before calling init() of&nbsp;another one. But if you share I/O lines between i2c and spi, you need some switching/blocking schematic for i2c bus.</p><div style="clear:both;"></div>
