Embedded Systems

This specialization covers programming small computers built into products: microcontroller architecture and memory, bare-metal C and register-level programming, on-chip peripherals -- timers, ADC, PWM, UART, SPI, I2C -- interrupt handling, real-time operating systems and scheduling, bootloaders and firmware update, low-power design, and debugging with a JTAG probe and a logic analyser rather than a print statement.
