How Arm Cortex-M0+ MCUs optimize general-purpose processing, sensing and control
Microcontrollers (MCUs) in embedded systems are the equivalent of air traffic control in a busy airport. MCUs sense their operating environment, take actions based on those observations, and communicate with related systems. They manage and control signals in an almost endless list of electronics, from digital thermometers to smoke detectors to heating, ventilation and air-conditioning motors.
