# TinyUSB + STM32 Tutorial (USB CDC) - Phil's Lab #168

**[Phil's Lab](https://daily.dev/sources/phils-lab)** · 25 min read · 0 upvotes · 0 comments

## Summary

A step-by-step walkthrough of integrating TinyUSB on an STM32H743 microcontroller to implement a USB CDC (Communications Device Class) virtual COM port. Covers STM32CubeIDE project setup, enabling the USB full-speed peripheral and interrupt, cloning the TinyUSB repo, configuring tusb_config.h and USB descriptors, wiring the interrupt handler, initializing TinyUSB in main, and testing a dual-port CDC echo program via a terminal. Also discusses why TinyUSB is a good alternative to ST's USBX/ThreadX middleware.
