System Peripherals
R2026bAccess and manage essential hardware interfaces on Raspberry Pi hardware using MATLAB® functions and Simulink® blocks. Read from and write to GPIO pins, control onboard LEDs, interface with rotary encoders, and acquire analog data using external ADCs. Use these capabilities to build interactive, sensor-driven, and automated applications.
