The ATmega series of microcontrollers from Microchip is widely used in embedded systems, hobby electronics, and Arduino platforms.
In this section you will learn how to program ATmega microcontrollers using embedded C. Topics include GPIO programming, interrupts, timers, communication interfaces such as UART, SPI and I2C, and practical firmware development techniques.
These tutorials assume basic knowledge of C programming and microcontroller concepts.
