Discovery kit with STM32F429ZI MCU
Introduction
The 32F429IDISCOVERY Discovery kit allows users to easily develop applications with the
STMicroelectronics Arm® Cortex®-M4 core-based STM32F429 high-performance
microcontroller. It includes an ST-LINK/V2 or ST-LINK/V2-B embedded debug tool, a 2.4"
QVGA TFT LCD, an external 64-Mbit SDRAM, an ST MEMS gyroscope, a USB OTG
Micro-AB connector, LEDs and push-buttons.
The board comes with the STM32 comprehensive free software libraries and examples
available with the STM32Cube package, as well as a direct access to the Arm® Mbed
Enabled™ resources at the http://mbed.org website.

Embedded ST-LINK/V2 (or V2-B)
The ST-LINK/V2 on 32F429IDISCOVERY or the ST-LINK/V2-B on STM32F429I-DISC1 is
embedded as programming and debugging tool. Virtual COM port and USB mass storage
features are supported by the ST-LINK/V2-B only for Mbed compatibility.
The ST-LINK/V2-B makes the STM32F4429I-DISC1 boards Mbed Enabled. The embedded
ST-LINK/V2 (or V2-B) supports only SWD for STM32 devices. For information about
debugging and programming features refer to ST-LINK/V2 in-circuit debugger/programmer
for STM8 and STM32, User manual (UM1075), which describes in detail all the
ST-LINK/V2 features.
The changes on ST-LINK/V2-B versus ST-LINK/V2 version are listed below.
New features supported on ST-LINK/V2-B are:
•
Virtual COM port interface on USB
•
Mass storage interface on USB
Features not supported on ST-LINK/V2-B are:
•
SWIM interface
•
Minimum supported application voltage limited to 3 V
•
USB power management request for more than 100 mA power on USB
Known limitation:
•
Activating the readout protection on the ST-LINK/V2-B target, prevents the target
application from running afterwards. The target readout protection must be kept
disabled on the ST-LINK/V2-B boards.
There are two different ways to use the embedded ST-LINK/V2-B, depending on the jumper
states (see Table 3):
•
Programming/debugging the STM32 on board (refer to Section 6.3.4: Using STLINK/V2 (or V2-B) to program/debug the STM32F429ZIT6 on board to program/debug
the STM32F429ZIT6 on board)
•
Programming/debugging the STM32 in an external application board, using a cable
connected to SWD connector CN2 (refer to chapter: Section 6.3.5: Using ST-LINK/V2
(or V2-B) to program/debug an external STM32 application)

Drivers
The ST-LINK/V2 (or V2-B) requires a dedicated USB driver, which, for Windows® 7, 8 and
10 can be found at the www.st.com website. In case the STM32 Discovery is connected to
the PC before the driver is installed, some Discovery interfaces may be declared as
“Unknown” in the PC device manager. In this case the user must install the driver files (see
Figure 6: Updating the list of drivers in Device Manager) and update the driver of the
connected device from the device manager.
Note:
Prefer using the “USB Composite Device” handle for a full recovery.
Figure 6. Updating the list of drivers in Device Manager
6.3.2
ST-LINK/V2 (or V2-B) firmware upgrade
The ST-LINK/V2 (or V2-B) embeds a firmware upgrade mechanism for in-situ upgrade
through the USB port. As the firmware may evolve during the life time of the ST-LINK/V2 (or
V2-B) product (for example new functionalities, bug fixes, support for new microcontroller
families), it is recommended to visit the www.st.com website, before starting to use the
Discovery board and periodically, to stay up-to-date with the latest firmware version.
6.3.3
VCP configuration
The ST-LINK/V2-B on STM32F429I-DISC1 supports virtual COM port (VCP) on U2 pin 12
(ST-LINK_TX) and U2 pin 13 (ST-LINK_RX), which are connected to the STM32F429 target
STM32 USART1 (PA9, PA10) for Mbed support, thanks to the SB11 and SB15 solder
bridges.
The SB11 (PA9) and SB15 (PA10) default configurations for 32F429IDISCOVERY and
STM32F429I-DISC1 are given in Table 5: Solder bridges.

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

Using ST-LINK/V2 (or V2-B) to program/debug
an external STM32 application
It is very easy to use the ST-LINK/V2 (or V2-B) to program the STM32 on an external
application. Simply remove the two jumpers from CN4 as shown in Figure 8 and connect the
application to the CN3 debug connector according to Table 4.
Note:
SB7 must be OFF if CN2 pin 5 is used in an 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 supply, 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 the 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 it is protected by D4
and D5 diodes when both USBs are connected (in this case the 5 V power is around
4.4 volts).

USB OTG supported
The STM32F429ZIT6 is used to drive only the 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, a mouse and so on.
Two LEDs are dedicated to this module:
6.8
•
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 a full-scale of ±245/±500/±2000 dps and is capable of measuring rates
with a user-selectable bandwidth.
The STM32F429ZIT6 controls this motion sensor through the SPI interface.
6.9
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.
6.10
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, a
power-saving and a power-down modes. All signals are registered on the positive edge of
the clock signal, CLK.
The STM32F429ZIT6 reads and writes data at 80 MHz.
6.11
JP3 (Idd)
Jumper JP3, labeled Idd, allows the consumption of STM32F429ZIT6 to be measured by
removing the jumper and connecting an ammeter.
18/36
•
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).
