Bare-Metal STM32 Programming

Bare-Metal STM32 Programming: From Startup Code to Peripherals is a complete, no-nonsense guide to writing firmware directly on the metal. No HAL. No framework. No hidden layers. You will learn the startup code, the linker script, the clock tree, and every peripheral you need — GPIO, interrupts, timers, UART, SPI, I2C, ADC, DMA, RTC, power modes, and the bootloader. Every chapter is dense with register-level code, datasheet references, and the debugging techniques that make bare-metal development tractable. By the end, you will not just blink an LED. You will understand your microcontroller.
