Interfacing & Communication

How microcontrollers talk to sensors, displays, and each other. The three workhorse digital protocols — UART, SPI, and I²C — plus analog interfacing (ADC/DAC) and how to choose the right bus for a job. The bridge between L4's microcontroller and the real components it controls.
