Embedded ST-LINK/V2
The ST-LINK/V2 programming and debugging tool is integrated on the STM32F429
Discovery board. The embedded ST-LINK/V2 can be used in 2 different ways according to
the jumper states (see Table 3):
•

Program/debug the MCU on board,

•

Program/debug an MCU in an external application board using a cable connected to
SWD connector CN3.

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.
Figure 6. Typical configuration

Hardware requirements:
- USB cable type A to mini-B
- Computer with Windows XP, Vista or 7

Development toolchains:
- Altium TASKING VX-Toolset
- Atollic TrueSTUDIO
- IAR EWARM
- Keil MDK-ARM

Using ST-LINK/V2 to program/debug the STM32F429ZIT6 on board
To program the STM32F429ZIT6 on board, simply plug in the two jumpers on CN4, as
shown in Figure 7 in red, but do not use the CN3 connector as that could disturb the
communication with the STM32F429ZIT6 of the STM32F429 Discovery board.

Using ST-LINK/V2 to program/debug an external STM32 application
It is very easy to use the ST-LINK/V2 to program the STM32 on an external application.
Simply remove the two jumpers from CN4 as shown in Figure 8, and connect your
application to the CN3 debug connector according to Table 4.

Note:

SB7must be OFF if you use CN2 pin 5 in your external application.

Hardware layout

Power supply and power selection
The power supply is provided either by the host PC through the USB cable, or by an
external 5 V power supply.
The D1 and D2 diodes protect the 5 V and 3 V pins from external power supplies:
•

5 V and 3 V can be used as output power supplies when another application board is
connected to pins P1 and P2.
In this case, the 5 V and 3 V pins deliver a 5 V or 3 V power supply and the power
consumption must be lower than 100 mA.

•

5 V and 3 V can also be used as input power supplies, e.g. when the USB connectors
are not connected to the PC.
In this case, the STM32F429 Discovery board must be powered by a power supply unit
or by an auxiliary equipment complying with standard EN-60950-1: 2006+A11/2009,
and must be Safety Extra Low Voltage (SELV) with limited power capability.

Note:

The board can also be powered through the USB USER connector and is protected by D4
and D5 diodes when both USBs are connected (in which case, the 5 V power is around
4.4 volts).

LEDs

4.5

•

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:
The red LED indicates that the board is powered.

•

User LD3:
The green LED is a user LED connected to the I/O PG13 of the STM32F429ZIT6.

•

User LD4:
The red LED is a user LED connected to the I/O PG14 of the STM32F429ZIT6.

•

User LD5:
The green LED indicates when VBUS is present on CN6 and is connected to PB13 of
the STM32F429ZIT6.

•

User LD6:
The red LED indicates an overcurrent from VBUS of CN6 and is connected to the I/O
PC5 of the STM32F429ZIT6.

Pushbuttons
•

B1 USER:
User and Wake-Up button connected to the I/O PA0 of the STM32F429ZIT6.

USB OTG supported
The STM32F429ZIT6 is used to drive only USB OTG full speed on this board. The USB
micro-AB connector (CN6) 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:

•

LD5 (green LED) indicates when VBUS is active

•

LD6 (red LED) indicates an overcurrent from a connected device.

Gyroscope MEMS (ST MEMS L3GD20)
The L3GD20 is an ultra-compact, low-power, three-axis angular rate sensor. It includes a
sensing element and an IC interface able to provide the measured angular rate to the
external world through the I2C/SPI serial interface.
The L3GD20 has dynamically user-selectable full scales of ± 250 dps/500 dps/±2000 dps
and is capable of measuring rates.
The STM32F429ZIT6 MCU controls this motion sensor through the SPI interface.

4.8

TFT LCD (Thin-film-transistor liquid-crystal display)
The TFT LCD is a 2.41" display of 262 K colors. Its definition is QVGA (240 x 320 dots) and
is directly driven by the STM32F429ZIT6 using the RGB protocol. It includes the ILI9341
LCD controller and can operate with a 2.8 ±0.3 V voltage.
The STM32F429ZIT6 MCU controls this motion sensor through the SPI interface.

4.9

64-Mbit SDRAM (1Mbit x 16-bit x 4-bank)
The 64-Mbit SDRAM is a high speed CMOS, dynamic random-access memory designed to
operate in 3.3 V memory systems containing 67,108,864 bits. it is internally configured as a
quad-bank DRAM with a synchronous interface. Each 16,777,216-bit bank is organized as
4,096 rows by 256 columns by 16 bits. The 64-Mbit SDRAM includes an AUTO REFRESH
MODE, and a power-saving, power-down mode. All signals are registered on the positive
edge of the clock signal, CLK.
The STM32F429ZIT6 MCU reads and writes data at 80 MHz.

4.10

JP3 (Idd)
Jumper JP3, labeled Idd, allows the consumption of STM32F429ZIT6 to be measured by
removing the jumper and connecting an ammeter.

16/35

•

Jumper on: STM32F429ZIT6 is powered (default).

•

Jumper off: an ammeter must be connected to measure the STM32F429ZIT6 current,
(if there is no ammeter, the STM32F429ZIT6 is not powered).
