Implementation of an USB-IDE/PATA converter on a STM32F4DISCOVERY dev board (based on STM32F407VG microcontroller); converts an old IDE hard drive in a standard USB mass storage device, thus no drivers are required on the PC side. USB is limited to 1.1, top transfer speed reached is about 1.1MB/s.

Based on FreeRTOS and TinyUSB; the IDE/PATA driver is written from scratch using GPIOs, inspired by similar projects on the 8051 and Raspberry PI.

The board is mounted on a custom PCB which can be found here.

Developed as exam project for the Progettazione di Sistemi Operativi course @ Università degli Studi di Milano.
