5 Quick start

The STM32F3DISCOVERY board is a low-cost and easy-to-use development kit to

evaluate quickly and start development with an STM32F3 series microcontroller. Before

installing and using the product, accept the Evaluation Product License Agreement from the

www.st.com/stm32f3discovery web page. For more information on the

STM32F3DISCOVERY board and demonstration software, visit the

www.st.com/stm32f3discovery web page.

5.1 Getting started

Follow the sequence below to configure the STM32F3DISCOVERY board and launch the

DISCOVER application:

1. Check the jumper positions on the board, JP3 ON, CN4 ON (DISCOVERY selected).

2. Connect the STM32F3DISCOVERY board to a PC with a USB cable Type-A or USB

Type-C®to Mini-B through the USB ST-LINK or USB USER connector to power the

board. The red LEDs LD1 (PWR) and LD2 (COM) light up.

3. The eight LED indicators blink sequentially.

4. Press the USER button to enable the ST MEMS gyroscope. Hold the board horizontally

then tilt it. Observe how the blinking of the LEDs indicates the gyroscope movement.

Press the USER button again and the LEDs restart blinking sequentially.

5. Press the USER button to enable the MEMS acceleration sensor. Hold the board

horizontally then tilt it. Observe how the blinking of the LEDs indicates the tilt of the

board relative to the horizontal plane. Press the USER button again and the LEDs

restart blinking sequentially.

6. Press the USER button. LD3, LD6, LD7, and LD10 are ON. The board is recognized as

a standard mouse (the board must be connected through the USB USER connector).

Move the board to control the cursor on the screen. Press the USER button again and

the LEDs restart blinking sequentially.

7. The demo application software as well as other software examples for exploring

STM32F3 features are available at www.st.com/stm32f3discovery.
