Engineers write code (usually in ) using an Integrated Development Environment (IDE) like STM32CubeIDE or Keil. 2. The Abstraction Layer

To understand how the STM32F103 ARM microcontroller works, let's take a closer look at its architecture and the embedded systems development process.

Modern STM32 work uses (a graphical configurator) and the HAL library . With HAL, you click pins to assign functions (e.g., USART on PA9/PA10), set clock trees visually, and generate initialization code automatically. HAL functions handle high-level tasks:

The practical work of developing an embedded system on the STM32F103 involves several stages:

: It delivers approximately 1.25 DMIPS/MHz, featuring single-cycle multiplication and hardware division for efficient data handling.
