STM32F4DISCOVERY
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:
2.2
2.3
2.4
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.

Embedded ST-LINK/V2
The ST-LINK/V2 programming and debugging tool is integrated on the
STM32F4DISCOVERY. The embedded ST-LINK/V2 can be used in 2 different ways
according to the jumper states (see Table 2):
●
Program/debug the MCU on board,
●
Program/debug an MCU in an external application board using a cable connected to
SWD connector CN2.
The embedded ST-LINK/V2 supports only SWD for STM32 devices. For information about
debugging and programming features refer to user manual UM1075 (ST-LINK/V2 in-circuit
debugger/programmer for STM8 and STM32) which describes in detail all the ST-LINK/V2
features.

Using ST-LINK/V2 to program/debug the STM32F4 on board
To program the STM32F4 on board, simply plug in the two jumpers on CN3, as shown in
Figure 8 in red, but do not use the CN2 connector as that could disturb communication with
the STM32F407VGT6 of the STM32F4DISCOVERY.

It is very easy to use the ST-LINK/V2 to program the STM32 on an external application.
Simply remove the 2 jumpers from CN3 as shown in Figure 9, and connect your application
to the CN2 debug connector according to Table 3.
Note:
SB11 must be OFF if you use CN2 pin 5 in your external application.

STM32F4DISCOVERY
Power supply and power selection
The power supply is provided either by the host PC through the USB cable, or by an external
5V power supply.
The D1 and D2 diodes protect the 5V and 3V pins from external power supplies:
4.4
4.5
16/38
●
5V and 3V can be used as output power supplies when another application board is
connected to pins P1 and P2.
In this case, the 5V and 3V pins deliver a 5V or 3V power supply and power
consumption must be lower than 100 mA.
●
5V can also be used as input power supplies e.g. when the USB connector is not
connected to the PC.
In this case, the STM32F4DISCOVERY board must be powered by a power supply unit
or by auxiliary equipment complying with standard EN-60950-1: 2006+A11/2009, and
must be Safety Extra Low Voltage (SELV) with limited power capability.
LEDs
●
LD1 COM: LD1 default status is red. LD1 turns to green to indicate that
communications are in progress between the PC and the ST-LINK/V2.
●
LD2 PWR: red LED indicates that the board is powered.
●
User LD3: orange LED is a user LED connected to the I/O PD13 of the
STM32F407VGT6.
●
User LD4: green LED is a user LED connected to the I/O PD12 of the
STM32F407VGT6.
●
User LD5: red LED is a user LED connected to the I/O PD14 of the STM32F407VGT6.
●
User LD6: blue LED is a user LED connected to the I/O PD15 of the STM32F407VGT6.
●
USB LD7: green LED indicates when VBUS is present on CN5 and is connected to PA9
of the STM32F407VGT6.
●
USB LD8: red LED indicates an overcurrent from VBUS of CN5 and is connected to the
I/O PD5 of the STM32F407VGT6.
Pushbuttons
●
B1 USER: User and Wake-Up button connected to the I/O PA0 of the
STM32F407VGT6.
●
B2 RESET: Pushbutton connected to NRST is used to RESET the STM32F407VGT6.

Hardware and layout
On board audio capability
The STM32F4 uses an audio DAC (CS43L22) to output sounds through the audio mini jack
connector.
The STM32F4 controls the audio DAC through the I2C interface and processes digital
signals through I2S connection or analog input signal.
●
●
4.7
The sound can come independently from different inputs:
–
ST MEMS microphone (MP45DT02): digital using PDM protocol or analog when
using the low pass filter.
–
USB connector: from external mass storage such as a USB key, USB HDD, and so
on.
–
Internal memory of the STM32F4.
The sound can be output in different ways through audio DAC:
–
Using I2S protocol
–
Using the STM32F4 DAC to analog input AIN1x of the CS43L22
–
Using the microphone output directly via a low pass filter to analog input AIN4x of
the CS43L22
USB OTG supported
The STM32F4 is used to drive only USB OTG full speed on this board. The USB micro-AB
connector (CN5) allows the user to connect a host or device component, such as a USB key,
mouse, and so on.
Two LEDs are dedicated to this module:
4.8
●
LD7 (green LED) indicates when VBUS is active
●
LD8 (red LED) indicates an overcurrent from connected device
Motion sensor (ST MEMS LIS302DL)
The LIS302DL is an ultra compact low-power three-axis linear accelerometer.
It includes a sensing element and an IC interface able to provide the measured acceleration
to the external world through I2C/SPI serial interface.
The LIS302DL has dynamically user selectable full scales of ±2g/±8g and it is capable of
measuring acceleration with an output data rate of 100 Hz or 400 Hz.
The STM32F4 controls this motion sensor through the SPI interface.
4.9
JP1 (Idd)
Jumper JP1, labeled Idd, allows the consumption of STM32F407VGT6 to be measured by
removing the jumper and connecting an ammeter.
●
Jumper on: STM32F407VGT6 is powered (default).
●
Jumper off: an ammeter must be connected to measure the STM32F407VGT6 current,
(if there is no ammeter, the STM32F407VGT6 is not powered).
