NRF52840 SPI with NCS 2.8 and above

Hi David,

When using SPI to communicate with a sensor, the recommended way is to use a device driver for that SPI sensor rather than using the SPI API directly.
Searching for spi_dt_spec in the SDK will yield some examples, but most are from device driver files.

Best regards,
Marte

Thank you Marte for the very speedy response!

By committing to Nrf Connect / Zephyr I feel obligated to do things the Zephyr way. The example you have cited does not seem to use the same struct as the Dev Academy shows. Can Nordic Semi supply an example that:

1. Uses the current NCS 2.9 SPI API, that is to say spi_dt_spec as shown in the Dev Academy SPI exercise

AND

2. Allows me to send and receive bytes to a generic SPI without writing a complete device driver for that particular SPI sensor.

Regards,

David Carlin

Hi David,

There is an unofficial sample made by a former Nordic employee available here: https://github.com/too1/ncs-spi-master-slave-example.

This is made for nRF Connect SDK v2.5.2, but it should work for later versions as well.

Best regards,
Marte
