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

You also have to set what instance you want to use of the SPI. for example CONFIG_NRFX_SPI1 or CONFIG_NRFX_SPIM1, etc.

My guess as to why you can send more in the nRF5 SDK than in NCS is because you've set different buffer and tx/rx lengths in the two projects you're running.

Best regards,

Simon
