Hello!
I am returning to software development for a BLE Mesh project on the NRF52840 after being focused on the hardware development for several months. I see that NCS is now up to 2.9 and I am following the general Nordic recommendation to always use the latest SDK and tools.
It appears that there is a significant change in setting up the SPI on 2.8 and above. I have reviewed the Dev Academy lesson on the SPI however the example in the Dev Academy uses a sensor with a well established device driver. To use struct spi_dt_spec it appears that the SPI device driver must be included in the overlay reference to &SPI. I looked at the Dev Academy Device Driver lesson and the prospect of learning how to write a device driver seems overwhelming to me. I have been programming microcontrollers in C for more than 25 years and one reason I like SPI devices is their simplicity - send a byte, get a byte. Having to write a device driver to do that seems unreasonable.
I can find no examples for the SPI past NCS 2.5. Before I went to 2.8 for my Mesh project I was at 2.6 and my SPI routine was working fine. Please advise me on how to use the SPI while keeping current with NCS releases.
Regards,
David Carlin
