UM1670 Quick start

5 Quick start

The STM32F429 Discovery is a low-cost and easy-to-use development kit to quickly

evaluate and start development with an STM32F4 microcontroller.

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

from www.st.com/stm32f4-discovery.

For more information on the STM32F429 Discovery board and for demonstration software,

visit www.st.com/stm32f4-discovery.

5.1 Getting started

Follow the sequence below to configure the STM32F429 Discovery board and launch the

DISCOVER application:

1. Ensure that the jumpers JP3 and CN4 are set ON (Discovery mode).

2. Connect the STM32F429 Discovery board to a PC using a USB cable Type-A/Mini-B

through the USB ST-LINK connector CN1, to power the board, the LEDs LD2 (PWR)

and LD1 (COM).

3. The following applications are available on the screen:

– Clock/Calendar and Game

– Video Player and Image Browser (play videos and view images from the USB

mass storage connected to CN6)

– Performance monitor (watch the CPU load and run a graphical benchmark)

– System Info

4. The demonstration software, as well as other software examples, are available at the

www.st.com/stm32f4-discovery web page.

5. Develop applications starting from the examples.
