Hardware Hacking 101: Interfacing With SPI
Introduction Welcome back to our series on an introduction to hardware hacking! In this post we will be covering the Serial Peripheral Interface (SPI) protocol, a commonly used serial bus protocol which allows hardware components to communicate with each other. The goal of this post is to serve as a guide for security researchers and hardware hackers to easily interface with target devices. Many embedded devices use SPI to access persistent data stored on flash memory.
