: Combines the high code density of 16-bit instructions with the performance of 32-bit instructions.
Videos are good for demonstrations, but PDFs (especially official reference manuals) are authoritative and searchable. When you get a compilation error due to a wrong register bit, only the PDF has the exact answer.
It covers the "meat" of embedded systems—timers, serial communication, ADC (Analog-to-Digital Conversion), and PWM (Pulse Width Modulation)—using the Blue Pill board as the primary learning tool. the stm32f103 arm microcontroller and embedded systems pdf

Unlike a desktop PC, an embedded microcontroller must respond to external events within strict timing windows. The STM32F103’s nested vectored interrupt controller (NVIC) supports up to 60 maskable interrupt channels, enabling deterministic responses. : Combines the high code density of 16-bit
while(1) GPIOC->BSRR = (1 << 13); // Set high delay(1000000); GPIOC->BRR = (1 << 13); // Reset low delay(1000000);
A significant driver of the STM32F103's popularity is its powerful core. The ARM Cortex-M3 is a 32-bit RISC processor designed for low-cost and low-power applications. It includes advanced features like a Nested Vectored Interrupt Controller (NVIC) for fast interrupt handling (down to 6 CPU cycles) and the Thumb-2 instruction set for high code density. It covers the "meat" of embedded systems—timers, serial
Support for STM32CubeIDE, Keil MDK, IAR, and open-source options like PlatformIO and GCC. 3. Architecture and Peripherals Explained
An embedded system is a dedicated computer system designed for specific control functions. The STM32F103 exemplifies every core concept of embedded design:
