This is a tutorial about the SPI of RP2040. The author starts to describe SPI very detail.
If you want to know SPI communication, this tutorial is good for you.

Have you ever heard of PrimeCell Synchronous Serial Port? I had never heard it before.

The author used 2 WizFi360-EVB-Pico and connected SPI between 2 boards.

You can learn about RP2040 SPI central and peripheral nodes also, RP2040 SPI receive interrupt.

Thank you for reading.
