STM32 UART CLI

A UART command-line interface project built on STM32 using interrupt-driven UART RX and a ring buffer.

Features

• UART RX interrupt
• Ring buffer
• CLI prompt
• Backspace support
• Commands:
  • help
  • led on
  • led off
  • adc read
  • pwm set <0-100>

Peripherals Used

• UART
• GPIO
• ADC
• TIM PWM

Project Goal

This project was built to practice embedded firmware architecture, command parsing, and peripheral control on STM32.

Future Improvements

• Cleaner command table
• Separate driver modules
• FreeRTOS version
• Better error handling
