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.

4.2.1 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.

4.2.2 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.

4.3 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).

4.4 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: 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.

4.5 Pushbuttons

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

• B2 RESET: The pushbutton connected to NRST is used to RESET the STM32F429ZIT6.


16/35 DocID025175 Rev 1

4.6 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.

4.7 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.

• 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).
