Implementation of an USB-IDE/PATA converter on a STM32F730Z 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 2.0 Based on FreeRTOS and [TinyUSB](https://github.com/hathach/tinyusb); the IDE/PATA driver is written from scratch using GPIOs, inspired by similar projects on the [8051](https://www.pjrc.com/tech/8051/ide/) and [Raspberry PI](https://github.com/Manawyrm/pata-gpio). The board is mounted on a custom PCB which can be found [here](https://github.com/gianluca-nitti/ide-usb-pcb). Developed as exam project for the [Progettazione di Sistemi Operativi](https://labonline.ctu.unimi.it/course/info.php?id=215) course @ Università degli Studi di Milano.
