Unlike older 8-bit registers, the Cortex-M3 uses a 32-bit RISC (Reduced Instruction Set Computer) architecture operating at frequencies up to 72 MHz. It features a 3-stage pipeline (Fetch, Decode, Execute) and supports the Thumb-2 instruction set, which blends 16-bit and 32-bit instructions to achieve high code density and execution speed.

And then, on the serial monitor:
A functional development environment is critical for debugging low-level hardware issues. Integrated Development Environments (IDEs)
The "Blue Pill" development board , which features the STM32F103C8T6, is incredibly inexpensive. This accessibility makes it a favorite for prototyping and mass-producing cost-sensitive devices. 3. Core Principles of STM32F103 Embedded System Work int main(void) // create the tasks task_t tasks[]
The microcontroller utilizes a Harvard architecture, meaning it possesses separate bus paths for instructions and data. Up to 512 KB for storing application code.
The heart of the STM32F103 is the processor. Unlike older 8-bit chips (like the Arduino Uno's ATmega328P), this is a 32-bit architecture , allowing it to process much larger chunks of data in a single clock cycle. Speed: Runs at up to 72 MHz.
The ARM Cortex-M3 uses a linear, 4 GB address space. Embedded engineers map peripherals, flash memory, and RAM to specific memory addresses, allowing direct manipulation of hardware via registers. B. Hardware Abstraction Layer (HAL) Mastering the STM32F103: A Deep Dive into ARM
