SPI | Raspberry Pi Pico Workshop: Chapter 4.3

🔗 The full course : core-electronics.com.au/cours...
SPI or Serial Peripheral Interface, is a blazingly fast communication protocol that we can use in high-speed applications such as cameras, displays and mass storage device adapters. In this video, we will be taking a look at the pros and cons of SPI, when you would use it, and also covering an example of wiring up and using an SPI micro SD card adapter with the Pico to perform some data logging.
