Embedded C for ARM Cortex-M: Registers, Interrupts, and Drivers

Embedded C for ARM Cortex-M is a complete, no-nonsense guide to writing production-quality firmware for the most popular 32-bit microcontroller family in the world. It skips the vendor HAL tutorials and goes straight to the metal — register-level GPIO, the NVIC, timers, UART, SPI, I2C, ADC, DMA, power modes, watchdogs, and the bootloader patterns used in real products. You will learn to write drivers three ways (blocking, interrupt-driven, DMA-driven), verify them with host-side unit tests,...
