4.2 Embedded ST-LINK/V2The ST-LINK/V2 programming and debugging tool is integrated on the STM32F3DISCOVERY. The embedded ST-LINK/V2 can be used in two different ways according to the jumper states (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 7. Typical configuration

4.2.1 Using ST-LINK/V2 to program/debug the STM32F303VCT6 on boardTo program the STM32F303VCT6 MCU on the board, simply plug in the two jumpers on CN4, as shown in Figure 8 in red, but do not use the CN3 connector as that could disturb communication with the STM32F303VCT6 of the STM32F3DISCOVERY.

Table 3. Jumper states Jumper state Description

Both CN4 jumpers ON ST-LINK/V2 functions enabled for on-board programming (default)

Both CN4 jumpers OFF ST-LINK/V2 functions enabled for application through external CN3 connector (SWD supported)

4.2.2 Using ST-LINK/V2 to program/debug an external STM32 applicationIt 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 9, and connect your application to the CN3 debug connector according to Table 4.

Note: SB7 must be OFF if you use the CN3 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 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 power consumption must be lower than 100 mA.

5 V and 3 V can also be used as input power supplies, for example when the USB connectors are not connected to the PC. In this case, the STM32F3DISCOVERY 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.

Note: The board can be also 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 PWR: red LED indicates that the board is powered. LD2 COM: LD2 default status is red. LD2 turns to green to indicate that

communications are in progress between the PC and the ST-LINK/V2. User LD3: red LED is a user LED connected to the I/O PE9 of the STM32F303VCT6. User LD4: blue LED is a user LED connected to the I/O PE8 of the STM32F303VCT6. User LD5: orange LED is a user LED connected to the I/O PE10 of the

STM32F303VCT6. User LD6: green LED is a user LED connected to the I/O PE15 of the

STM32F303VCT6. User LD7: green LED is a user LED connected to the I/O PE11 of the

STM32F303VCT6. User LD8: orange LED is a user LED connected to the I/O PE14 of the

STM32F303VCT6. User LD9: blue LED is a user LED connected to the I/O PE12 of the STM32F303VCT6. User LD10: red LED is a user LED connected to the I/O PE13 of the STM32F303VCT6.

4.5 Pushbuttons B1 USER: user and wake-up button connected to the I/O PA0 of the STM32F303VCT6. B2 RESET: pushbutton connected to NRST is used to RESET the STM32F303VCT6.


18/36 Doc ID 023594 Rev 3

4.6 USB device supportedThe STM32F303VCT6 MCU is also used to drive the second USB mini-B connector (USB USER) which allows the board to be used as a USB Device. The STM32F3DISCOVERY can then act as a USB joystick, mouse, or other similar device. If both USBs are connected, diodes D4 and D5 protect the board and use the power from the USB ST-LINK.The board can be powered through this USB USER connector, then LED1 PWR lights, LED2 COM blinks and it can run an application in standalone mode.

4.7 E-compass/accelerometer MEMS (ST MEMS LSM303DLHC)The LSM303DLHC is an ultra-compact low-power system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor. It includes a sensing element and an IC interface able to provide the measured acceleration to the external world through I2C serial interface.The LSM303DLHC has dynamically user-selectable full scales of 2g/8g and is capable of measuring acceleration, and a magnetic field full scale from 1.3g to 8.1g with an output data rate of 100 Hz or 400 Hz.The STM32F303VCT6 MCU controls this motion sensor through the I2C interface.

4.8 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 STM32F303VCT6 MCU controls this motion sensor through the SPI interface.

4.9 JP3 (Idd)Jumper JP3, labeled Idd, allows the consumption of the STM32F303VCT6 to be measured by removing the jumper and connecting an ammeter. Jumper on: STM32F303VCT6 is powered (default). Jumper off: an ammeter must be connected to measure the STM32F303VCT6 current.

If there is no ammeter, the STM32F303VCT6 is not powered.
