Quick start UM1472

6/42 DocID022256 Rev 4

2 Quick start

The STM32F4DISCOVERY is a low-cost and easy-to-use development kit to quickly

evaluate and start a development with an STM32F4 high-performance microcontroller.

Before installing and using the product, please accept the Evaluation Product License

Agreement from www.st.com/stm32f4-discovery.

For more information on the STM32F4DISCOVERY and for demonstration software, visit

www.st.com/stm32f4-discovery.

2.1 Getting started

Follow the sequence below to configure the STM32F4DISCOVERY board and launch the

DISCOVER application:

1. Check jumper position on the board, JP1 on, CN3 on (DISCOVERY selected).

2. Connect the STM32F4DISCOVERY board to a PC with a USB cable ‘type A to mini-B’

through USB connector CN1 to power the board. Red LED LD2 (PWR) then lights up.

3. Four LEDs between B1 and B2 buttons are blinking.

4. Press user button B1 to enable the ST MEMS sensor, move the board and observe the

four LEDs blinking according to the motion direction and speed. (If you connect a

second USB cable ‘type A to micro-B’ between PC and CN5 connector then the board

is recognized as standard mouse and its motion will also control the PC cursor).

5. To study or modify the DISCOVER project related to this demo, visit

www.st.com/stm32f4-discovery and follow the tutorial.

6. Discover the STM32F4 features, download and execute programs proposed in the list

of projects.

7. Develop your own application using available examples.

2.2 System requirements

•Windows PC (XP, Vista, 7)

•USB type A to Mini-B USB cable

2.3 Development toolchain supporting the STM32F4DISCOVERY

•Altium, TASKING™ VX-Toolset

•Atollic TrueSTUDIO®

•IAR Embedded Workbench®for ARM (EWARM)

•Keil™, MDK-ARM

4 Hardware and layout

The STM32F4DISCOVERY is designed around the STM32F407VGT6 microcontroller in a

100-pin LQFP package.

Figure 2illustrates the connections between the STM32F407VGT6 and its peripherals (ST-

LINK/V2, pushbutton, LED, Audio DAC, USB, ST MEMS accelerometer, ST MEMS

microphone, and connectors).

Figure 3and Figure 4help you to locate these features on the STM32F4DISCOVERY.
