4.2 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.

4.2.1 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.

Figure 8. STM32F4DISCOVERY connections image


Doc ID 022256 Rev 1 15/37

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 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.

4.3 Power supply and power selectionThe 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:

● 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.

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: 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.

4.5 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.


Doc ID 022256 Rev 1 17/37

4.6 On board audio capabilityThe 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.

● 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

4.7 USB OTG supportedThe 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:

● LD7 (green LED) indicates when VBUS is active

● LD8 (red LED) indicates an overcurrent from connected device

4.8 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).

SB12 (SWO) ON SWO signal of the CN2 connector is connected to PB3.

OFF SWO signal is not connected.

SB10 (STM_RST) OFF No incidence on STM32F103C8T6 (ST-LINK/V2) NRST signal.

ON STM32F103C8T6 (ST-LINK/V2) NRST signal is connected to GND.

SB18 (BOOT0)

ON BOOT0 signal of the STM32F407VGT6 MCU is held low through a 510 ohm pull-down resistor.

OFF BOOT0 signal of the STM32F407VGT6 MCU is held high through a 10 Kohm pull-up resistor.

SB19 (BOOT1)

OFF The BOOT1 signal of the STM32F407VGT6 MCU is held high through a 10 Kohm pull-up resistor.

ON The BOOT1 signal of the STM32F407VGT6 MCU is held low through a 510 ohm pull-down resistor.

1. Default SBx state is shown in bold.

2. SB13 and SB14 are OFF to allow the user to choose between MCO and X2 crystal for clock source.


Doc ID 022256 Rev 1 19/37

4.11 Extension connectorsThe male headers P1 and P2 can connect the STM32F4DISCOVERY to a standard prototyping/wrapping board. STM32F407VGT6 GPI/Os are available on these connectors. P1 and P2 can also be probed by an oscilloscope, logical analyzer or voltmeter.
