14 Hardware layout and configuration UM Embedded ST-LINK/V (or V-B) The ST-LINK/V on PCB version A or B or the ST-LINK/V-B on PCB version C is embedded as programming and debugging tool. Virtual COM port and USB mass storage features are supported by the ST-LINK/V-B only. The embedded ST-LINK/V (or V-B) supports only SWD for STM3 devices. For information about debugging and programming features refer to ST-LINK/V in-circuit debugger/programmer for STM8 and STM3, User manual (UM075), which describes in detail all the ST-LINK/V features. The changes on ST-LINK/V-B versus ST-LINK/V version are listed below. New features supported on ST-LINK/V-B are: Virtual Com port interface on USB Mass storage interface on USB The embedded-on-board features not supported either on ST-LINK/V or on ST-STLINK/V-B are: SWIM interface Minimum supported application voltage limited to 3 V USB power management request for more than 00 ma power on USB Known limitation: activating the readout protection on the STM3 target, prevents the target application from running afterwards. The readout protection must be kept disabled on the STM3 target. There are two different ways to use the embedded ST-LINK/V (or V-B), depending on the jumper states (see Table 3): Programming/debugging the STM3 on board (refer to Section 6..4: Using ST- LINK/V (or V-B) to program/debug the STM3F303VCT6 on board) Programming/debugging the STM3 in an external application board, using a cable connected to SWD connector CN (refer to Section 6..5: Using ST-LINK/V (or V-B) to program/debug an external STM3 application) Table 3. Jumper states Jumper state Both CN4 jumpers ON Both CN4 jumpers OFF Description ST-LINK/V (or V-B) functions enabled for on-board programming (default) ST-LINK/V (or V-B) functions enabled for application through external CN3 connector (SWD supported) 6.. Drivers The ST-LINK/V (or V-B) requires a dedicated USB driver, which, for Windows XP, 7, 8, can be found at the website. In case the STM3 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, and from the device manager he must update the driver of the connected device (see Figure 6). Note: Prefer using the "USB Composite Device" handle for a full recovery. 4/37 DocID03594 Rev 4

15 UM570 Hardware layout and configuration Figure 6. USB composite device 6.. ST-LINK/V (or V-B) firmware upgrade The ST-LINK/V (or V-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/V (or V-B) product (for example new functionalities, bug fixes, support for new microcontroller families), it is recommended to visit the website, before starting to use the Discovery board and periodically, to stay up-to-date with the latest firmware version VCP configuration The ST-LINK/V-B on STM3F3DISCOVERY supports virtual Com port (VCP) on U pin (ST-LINK_TX) and U pin 3 (ST-LINK_RX), which are connected to the STM3F303 MCU target STM3 USART (PA9, PA0), thanks to SB and SB5 solder bridges. The SB (PA9) and SB5 (PA0) default configurations for STM3F3DISCOVERY are given in Table 5: Solder bridges Using ST-LINK/V (or V-B) to program/debug the STM3F303VCT6 on board To program the STM3F303VCT6 MCU on the board, simply plug in the two jumpers marked in red on CN4, as shown in Figure 7: STM3F3DISCOVERY connections, but do not use the CN3 connector as that could disturb the communication with the STM3F303VCT6 of the STM3F3DISCOVERY.

16 Hardware layout and configuration UM570 Figure 7. STM3F3DISCOVERY connections 6..5 Using ST-LINK/V (or V-B) to program/debug an external STM3 application Note: It is very easy to use the ST-LINK/V (or V-B) to program the STM3 on an external application. Simply remove the two jumpers from CN4 as shown in Figure 8: ST-LINK/V connections, and connect the application to the CN3 debug connector according to Table 4. SB7 must be OFF if the CN3 pin 5 is used in an external application. Table 4.

18 Hardware layout and configuration UM 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. Note: The D and D 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 P and P. 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 00 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 STM3F3DISCOVERY board must be powered by a power supply unit or by auxiliary equipment complying with the standard EN : 006+A/009, and must be Safety Extra Low Voltage (SELV) with limited power capability. The board can be also powered through the USB USER connector and it is protected by D4 and D5 diodes when both USBs are connected (in which case, the 5 V power is around 4.4 volts). 6.4 LEDs LD PWR: red LED indicates that the board is powered. LD COM: LD default status is red. LD turns to green to indicate that communications are in progress between the PC and the ST-LINK/V. User LD3: red LED is a user LED connected to the I/O PE9 of the STM3F303VCT6. User LD4: blue LED is a user LED connected to the I/O PE8 of the STM3F303VCT6. User LD5: orange LED is a user LED connected to the I/O PE0 of the STM3F303VCT6. User LD6: green LED is a user LED connected to the I/O PE5 of the STM3F303VCT6. User LD7: green LED is a user LED connected to the I/O PE of the STM3F303VCT6. User LD8: orange LED is a user LED connected to the I/O PE4 of the STM3F303VCT6. User LD9: blue LED is a user LED connected to the I/O PE of the STM3F303VCT6. User LD0: red LED is a user LED connected to the I/O PE3 of the STM3F303VCT Push-buttons B USER: user and wake-up button connected to the I/O PA0 of the STM3F303VCT6. B RESET: push-button connected to NRST is used to RESET the STM3F303VCT6. 8/37 DocID03594 Rev 4

19 UM570 Hardware layout and configuration 6.6 USB device supported The STM3F303VCT6 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 STM3F3DISCOVERY 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 LED PWR lights, LED COM blinks and it can run an application in standalone mode. 6.7 ST MEMS E-compass (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 an I C serial interface. The LSM303DLHC has dynamically user-selectable full scales of ±g/±8g and is capable of measuring acceleration, and a magnetic field full scale from ±.3g to 8.g with an output data rate of 00 Hz or 400 Hz. The STM3F303VCT6 MCU controls this motion sensor through the I C interface. 6.8 ST MEMS Gyroscope (ST MEMS L3GD0) The L3GD0 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 I C/SPI serial interface. The L3GD0 has dynamically user-selectable full scales of ±50 dps/±500 dps/±000 dps and is capable of measuring rates. The STM3F303VCT6 MCU controls this motion sensor through the SPI interface. 6.9 JP3 (Idd) Jumper JP3, labeled Idd, allows the measurement of the consumption of the STM3F303VCT6 by removing the jumper and connecting an ammeter. Jumper on: STM3F303VCT6 is powered (default). Jumper off: an ammeter must be connected to measure the STM3F303VCT6 current. If there is no ammeter, the STM3F303VCT6 is not powered.
