Hi,

In my application, I want to read some sensor data through SPI Communication in nrf52840, can you please provide some code or please tell me how to implement the program using SPI for reading any sensor data. Please anyone help me on this.

Thanks.

Hello,

In nRF5 SDK, we have two examples: SPI example (using legacy nrf_drv_spi API) (https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/spi_master_example.html?cp=8_1_4_6_37) and nrfx_spim example (using newer nrfx_spim API) (https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/nrfx_spim_example.html?cp=8_1_4_6_38) . The second example is used if we need high SPIM3 instance on nRF52840.

Thanks.

Best Regards,

Thanks for the reply.

If I use the sample code means can I read sensor data is it possinle.

yes it is possible to send data from master device to slave. So, one device/board will run the SPI master example and another board will run the SPI slave example, you can see that the second board is receiving valid data.

You can find code from the installation folder of nRF5 SDk <InstallFolder>\examples\peripheral\spi, <InstallFolder>\examples\peripheral\nrfx_spim
