SPI in nrf connect sdk

[Vignesh R]

hi,

I'm using nrf connect sdk to communicate spi sensor.

which is better choice to use SPI in ncs (nrfx driver or zephyr ) ?

i) nrfx_driver: nrfx_spim_init(&spi, &spi_config, spim_event_handler, NULL);

ii) zephyr :      spim_dev = device_get_binding(DT_LABEL(MY_SPIM));

if I want to use zephyr, where can I configure the pins and particularly cs pin?

Hi

Either is fine, and it's mostly up to personal preference. I'm probably biased, but personally I prefer the nrfx drivers in general, as I'm most familiar with them. 

The API reference of Zephyrs SPI driver is available here, and the nRF Connect API is available here for SPI, and here for SPIM.

Best regards,

Simon
