The F103 series provides a wide array of built-in peripherals:
This article explores why the STM32F103 is a cornerstone of embedded system work, detailing its features, applications, and ecosystem. 1. Introduction to the STM32F103 Family
For the hobbyist, its low cost, the ubiquitous "Blue Pill" board, and compatibility with the Arduino IDE offer an unrivaled gateway into high-performance 32-bit development. For the professional engineer, its mature toolchain, featuring STM32CubeIDE and the HAL library, provides the reliability, flexibility, and advanced debugging features necessary for demanding industrial, medical, and IoT applications.
The STM32F103 houses up to three independent 12-bit Analog-to-Digital Converters with a conversion range from 0 to 3.6V. It supports injected and regular conversion groups, allowing critical analog signals (like motor current overloads) to interrupt routine analog readings instantly. 3. Communication Protocols
He gestured at the oscilloscope. “Look. The timing on the ADC for the pollen sensor is drifting. The STM32F103 has a 12-bit, 1 µs converter, but my interrupt handler is too slow. By the time the CPU services the flag, the sample is stale.”
A typical minimal system requires:
A simple program to toggle an LED on GPIO pin PC13 (typical Blue Pill onboard LED) demonstrates embedded systems work:
