2.1 Development and debug supportVersion 2 of the ST-LINK (ST-LINK/V2) is embedded on the board. This tool allows onboard program loading and debugging of the STM32F051R8T6 using the SWD interface. The third-party debug tools are also supported by the SWD connector CN10.

A specific driver must be installed on your PC for communication with the embedded ST-LINK/V2. This driver, called ST-LINK_V2_USBdriver.exe is available on the web. To download and install this driver, refer to the software and development tools page for the STM32F0 family on www.st.com.

Third-party toolchains, such as Atollic TrueSTUDIO, Keil MDK-ARM, IAR EWARM and TASKING VX-toolset for ARM Cortex-M, support ST-LINK/V2 according to Table 2.

The embedded ST-LINK/V2 is connected to the PC via a standard USB cable from connector CN13. The bicolor LED LD7 (COM) indicates the status of the communication as follows.

● Slow blinking Red/Off: at power-on before USB initialization.

● Fast blinking Red/Off: after the first correct communication between the PC and ST-Link/V2 (enumeration).

● Constant Red On: when initialization between the PC and ST-LINK/V2 is successfully finished.

● Constant Green On: after successful target communication initialization.

● Blinking Red/Green: during communication with the target.

● Red On: communication is finished and OK.

● Orange On: communication failure.

Note: The board can be powered via CN13 (embedded ST/LINK/V2 USB connector) even if an external tool is connected to CN9 (high density SWD connector) or CN10 (SWD connector).

The direction of this voltage translator is controlled by IO PB2 (the IO PA7 acts as MOSI when PB2 is high or as MISO when PB2 is LOW).

2.14 RF E2PROMAn RF E2PROM module ANT7-M24LR-A is mounted on connector CN2 and is connected to the I2C1 bus of the STM32F051R8T6. It shares the same I2C1 bus as the temperature sensor U8 and DDC on the HDMI_Source connector CN4.

2.15 HDMI CECTwo HDMI connectors CN3 and CN4 are available on the STM320518EVAL board.

● Connector CN3 is an HDMI sink connector with:

– DDC connected to I2C2 of the STM32F051R8T6

2.16 IR LED and IR receiverThe IR receiver TSOP34836 is connected to PB3 of the STM32F051R8T6 and a current around 100 mA on the IR LED is driven by PB9 through transistors T1 and T2 on the board.

Note: The IR LED may be driven by PB9 directly with a 20 mA current when SB3 is closed and R11 is removed.

2.17 Motor controlThe STM320518-EVAL evaluation board supports both asynchronous and synchronous three-phase brushless motor control via a 34-pin connector CN1. This connector provides all required control and feedback signals to and from the motor power-driving board. Available signals on this connector include emergency stop, motor speed, 3-phase motor current, bus voltage, heatsink temperature coming from the motor driving board and six channels of the PWM control signal going to the motor driving circuit.

Some PCB reworks are required for the motor control application to disconnect peripherals that share IOs with the motor control connector. These IOs need to be connected to the motor control connector.

● Remove resistors R89, R52, R19, R55, R32, R38, R42, R88, R83, R20, R36, R18 and R50.
