STM320518-EVAL

UM1537 User manual STM320518-EVAL evaluation board Introduction The STM320518-EVAL evaluation board is designed as a complete demonstration and development platform for STMicroelectronic's ARM cortex-M0 core-based STM32F051R8T6 microcontroller. It features two I2Cs, two SPIs, two USARTs, a 12-bit ADC, a 12-bit DAC, two GP comparators, internal 8 KB SRAM and 64 KB Flash, touch sensing, CEC and SWD debugging support. The full range of hardware features on the board is able to help you evaluate all peripherals (motor control connector, RS-232, RS-485, audio DAC, linear sensor, microphone ADC, TFT LCD, IrDA, IR LED, IR receiver, LDR, MicroSD card, CEC on two HDMI connectors, RF E2PROM, temperature sensor and so on) and develop your own applications. Extension headers make it possible to easily connect a daughterboard or wrapping board for your specific application. An ST-LINK/V2 is integrated on the board as an embedded in-circuit debugger and programmer for the STM32 MCU. May 2012 Figure 1. STM320518-EVAL evaluation board Table 1.

When the board is extracted from its plastic bag, please check that no component remains in the bag. The main components to verify are: 1. The 8 MHz crystal (X1) which may have been removed from its socket by a shock. 2. The MicroSD card which may have been ejected from the connector CN14 (left side of the board). 3. The dual interface EEPROM board (ANT7-M24LR-A) which may have been unplugged from the connector CN2 (top right corner of 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 STLINK/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. Table 2. Third-party toolchain support Manufacturer Toolchain From version... Atollic TrueSTUDIO 2.1 IAR EWARM 6.20.4 Keil MDK-ARM 4.20 TASKING VX-toolset for ARM Cortex-M 4.0.1 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. Note: 10/52 ● Slow blinking Red/Off: at power-on before USB initialization. ● Fast blinking Red/Off: after the first correct communication between the PC and STLink/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. 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). Doc ID 023059 Rev 1 UM1537 2.2 Hardware layout and configuration Power supply The STM320518-EVAL evaluation board is designed to be powered by a 5V DC power supply and to be protected by PolyZen from incorrect power plug-in events. It is possible to configure the evaluation board to use any of the following three sources for the power supply. ● 5V DC power adapter connected to CN15, the power jack on the board (power supply unit (PSU) on the silk screen).

Table 11. RS-485 related solder bridges Jumper SB11,SB12 2.8 Description The external failsafe biasing are enabled when solder bridges SB11 and SB12 are closed. Default setting: not fitted SB8 The bus termination is enabled when solder bridge SB8 is closed. Default setting: not fitted SB16 The AC termination is disabled when solder bridge SB16 is closed for high baud rate communication. Default setting: not fitted Linear sensor The linear sensor is supported on the STM320518-EVAL evaluation board and connected to four capacitive sensing channels (PB[11:14]) in group6 with an active shield connected to two capacitive sensing channels (PC5 and PB0) in group3. Note: The linear sensor is only fully functional when the STM320518-EVAL is powered on power mode 1 (both VDD and VDDA are connected to a fixed 3.3 V). It is potentially necessary to adjust the capacitor value of C14 and C15 and the firmware to adapt them to the voltage range from 2 V to 3.6 V of VDD on power modes 2 and 3. 2.9 MicroSD card The 2 GB (or more) MicroSD card connected to the SPI1 port of the STM32F051R8T6 is available on the board. MicroSD card detection is managed by the standard IO port PB15. 2.10 Analog input The two-pin header CN8 and 10 kohm potentiometer RV3 are connected to PC1 of the STM32F051R8T6 as an analog input. A low-pass filter can be implemented by replacing R60 and C36 with the correct resistor and capacitor values as required by the end-user application. 2.11 LDR (light dependent resistor) The VDDA is divided by the resistor bridge of the LDR VT9ON1 and 8.2 K resistor.

It shares the same I2C1 bus as the temperature sensor U8 and DDC on the HDMI_Source connector CN4. 2.15 HDMI CEC Two 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 – HPD controlled by I/O PA11 through transistor T3 – CEC connected to PB10 through transistor T4 Connector CN4 is an HDMI source connector with: – DDC connected to I2C1 of the STM32F051R8T6 and shared with the temperature sensor and RF E2PROM – HPD controlled by I/O PA8 – CEC connected to PB10 through transistor T4 – 5V HDMI powered by power switch U5 Signals TDMS D+[0,1,2], TDMS_CLK+, TDMS D-[0,1,2] and TDMS_CLK are connected together on these two HDMI connectors.

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 control The 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. ● Mount R25, R29, R30, R39, R4, R35, R37, R44, R22 and R41 with a 0 ohm resistor.
