nrf52840 3 wire spi using sdk

[Shinicy99]

Is it possible to use SDK of nrf52840 to configure a 3wire SPI?

I saw in some posts that i can not use directly the MISO pin and not assing it in the sdk's nrf function, but is the best way to proceed?

Hi

I agree with Hugh, there is no reason you shouldn't be able to set either the MISO or the MOSI pin to unassigned (0xFFFFFFFF) in order to run the SPI interface in 3-wire mode.
