Embedded Systems (C)

Program close to the metal. Master bare-metal C, register manipulation, interrupts, and drivers for microcontrollers like STM32.

Embedded systems run the world, from washing machines to cars. This course teaches 'Bare Metal' programming, where there is no Operating System. You will write C code to manipulate hardware registers directly. Master GPIO, Timers, PWM, and communication protocols like UART, I2C, and SPI. Learn to handle Interrupts (ISRs) for real-time responsiveness. We use the STM32 ARM Cortex-M architecture, the industry standard for modern embedded products.
