Embedded ST-LINK/V2
The ST-LINK/V2 programming and debugging tool is integrated on the
32F0308DISCOVERY. 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 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.

Using ST-LINK/V2 to program/debug the STM32 F0 on board
To program the STM32 F0 on board, simply plug in the two jumpers on CN2, as shown in
Figure 8 in red, but do not use the CN3 connector as that could disturb communication with
the STM32F030R8T6 of the 32F0308DISCOVERY.

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 CN2 as shown in Figure 9, and connect your application
to the CN3 debug connector according to Table 3.
Note:
SB19 and SB22 must be OFF if you use CN3 pin 5 in your external application.

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:
4.4
4.5
4.6
•
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 can also be used as input power supplies; for example, when the USB connector is
not connected to the PC.
In this case, the 32F0308DISCOVERY 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.
LEDs
•
LD1 PWR: Red LED indicates that the board is powered.
•
LD2 COM: Tricolor LED (COM) advises on the communication status as follows:
–
Slow blinking Red LED/Off: At power on before USB initialization
–
Fast blinking Red LED/Off: After the first correct communication between PC and
STLINK/V2 (enumeration)
–
Red LED On: When initialization between PC and ST-LINK/V2 is successfully
finished
–
Green LED On: After successful target communication initialization
–
Blinking Red/Green LED: During communication with target
–
Red LED On: Communication finished and OK
–
Orange LED On: Communication failure
•
User LD3: Green user LED connected to the I/O PC9 of the STM32F030R8T6.
•
User LD4: Blue user LED connected to the I/O PC8 of the STM32F030R8T6.
Push buttons
•
B1 USER: User push button connected to the I/O PA0 of the STM32F030R8T6.
•
B2 RESET: Push button used to RESET the STM32F030R8T6.
JP2 (Idd)
Jumper JP2, labeled Idd, allows the consumption of STM32F030R8T6 to be measured by
removing the jumper and connecting an ammeter.
16/39
•
Jumper on: STM32F030R8T6 is powered (default).
•

PF0 and PF1 can be used as GPIO or as HSE oscillator. By default these I/Os are
configured as GPIO, so SB16 and SB17 are closed, SB18 is open and R22, R23, C13 and
C14 are not populated.
An external HSE clock can be provided to the MCU in three ways:
•

MCO from ST-LINK. From MCO of the STM32F103. This frequency cannot be
changed, it is fixed at 8 MHz and connected to PF0-OSC_IN of the STM32F030R8T6.
Configuration needed:
–
SB16, SB18 CLOSED

Connecting modules on the prototyping board
Connecting modules on the prototyping board
This section gives some examples of how to connect ready-to-use modules available from
different manufacturers to the STM32F030 Value Line Discovery kit via the prototyping
board included in the kit.
Software examples, based on the connections described below, are available at
www.st.com/stm32f0-discovery.

Mikroelektronica accessory boards
Mikroelektronika, http://www.mikroe.com, has specified two standard connectors for their
accessory boards, named mikroBUS™ (http://www.mikroe.com/mikrobus_specs.pdf) and
IDC10.
MikroBUS™ is a 16-pin connector to connect accessory boards very quickly and easily to a
microcontroller board through SPI, USART or I2C communications, along with additional
pins such as Analog Input, PWM and Interrupt.
The set of mikroElektronika boards compatible with mikroBUS™ is called “Click boards”.
IDC10 is a 10-pin connector to connect the general purpose I/O of an MCU to other
accessory boards.
The tables below are one solution for connecting mikroBUS™ and IDC boards to the
32F0308DISCOVERY; this solution used in the different examples is available at
www.st.com/stm32f0-discovery.
