STM32F30xx Standard Peripheral Library
1.3.3 Utilities folder
This folder contains the abstraction layer allowing interacting with the human interface
resources (buttons, LEDs, LCD and COM ports (USARTs)) available on
STMicroelectronics evaluation boards. A common API is provided to manage these
different resources. It and can be easily tailored to support any other development board,
by adapting the initialization routine.
Additional drivers are provided to manage the different memories and storage media
available on these boards.
For each hardware module (e.g. LCD, I2C, EEPROM, external SRAM memory...)
the API is fully compatible across all STMicroelectronics evaluation board drivers.
The Utilities folder structure is shown below.

It contains common files and folder, plus a folder for STM32303C_EVAL board files.
