Getting started with STM32F072 Discovery kit software development tools
Introduction
This document describes the software environment recommendations required to build an application using the STM32F072 Discovery kit (32F072BDISCOVERY). The document provides guidelines to novice user on how to build and run a sample example and how to create and build his own application. It has the following structure: the first chapter presents the software and hardware requirements (some toolchains supporting the STM32 families,
ST-LINK/V2 installation and firmware package presentation). The second chapter provides step by step guidelines on how to execute and debug an application example using some toolchains:
IAR Embedded Workbench® for ARM (EWARM) by IAR systems,
Microcontroller Development Kit for ARM (MDK-ARM) by Keil
™,
TrueSTUDIO® by Atollic.
Although this user manual does not cover all the topics relevant to software development environments, it demonstrates the first basic steps necessary to get started with the compilers/debuggers and includes references for complementary information.

1. Register prior to downloading the toolchain
The STM32F072 Discovery board includes the ST-LINK/V2 embedded debug tool interface.
The interface requires to install the ST-LINK/V2 dedicated USB driver. The STM32F072
Discovery board includes an ST-LINK/V2 embedded debug tool interface that is supported by the following software toolchains:
IAR™ Embedded Workbench for ARM (EWARM)
The toolchain is installed by default in the C:\Program Files\IAR Systems\Embedded
Workbench x.x
directory on the PC local hard disk.
After installing EWARM, install the ST-LINK/V2 driver by running the ST-
Link_V2_USB.exe from IAR_INSTALL_DIRECTORY]\Embedded Workbench x.x\arm\drivers\ST-Link \ST-Link_V2_USBdriver.exe
RealView Microcontroller Development Kit (MDK-ARM) toolchain
The toolchain is installed by default in the C:\Keil directory on the PC local hard disk; the installer creates a start menu μ Vision4 shortcut.
When connecting the ST-LINK/V2 tool, the PC detects new hardware and asks to install the ST-LINK_V2_USB driver. The “Found New Hardware wizard” appears and

Note:
System requirements guides you through the steps needed to install the driver from the recommended location.
Atollic TrueSTUDIO® STM32
The toolchain is installed by default in the C:\Program Files\Atollic directory on the PC local hard disk.
The ST-Link_V2_USB.exe is installed automatically when installing the software toolchain.
Complementary information on the firmware package content and the STM32F072
Discovery board requirements are available in the user manual UM1674 - Getting started with the STM32F072 Discovery kit.
The embedded ST-LINK/V2 supports only SWD interface for STM32 devices.
The STM32F072 Discovery firmware applications, demonstration and IPs examples are provided in one single package and supplied in one single zip file. The extraction of the zip file generates one folder, STM32F072B-Discovery_FW_VX.Y.Z, which contains the following sub folders:
