The latest versions of the source code and associated documentation can be downloaded from www.st.com/stm32f0-discovery. This document describes step-by-step how to start using the STM32F072 Discovery kit demonstration. 1.1 Hardware requirements To configure the STM32F072B-DISCO board and start the demo, two ‘USB type A to Micro-B’ cables are required. Connect them between the host PC and the board as follows: USB connector CN1: to power on the STM32F072B-DISCO board from the USB ST-LINK USB connector CN2: to connect the board to the host PC as a USB Device Establish the connection with the STM32F072 Discovery board as shown in Figure 2. Check jumper positions on the board, JP2 and CN5 are set to ON (Discovery mode). Figure 2. Hardware environment 4/9 DocID025256 Rev 1 UM1674 1.2 Quick start Run pre-loaded demo Follow the sequence below (Function 0 to Function 3) to launch the demo application: Function 1 is executed and each click on user button B1 changes the executed function as shown in Table 1. Table 1. STM32F072B-DISCO functions and LEDs Function LED Displayed description Main function 0 LD3/4/5/6 blinking 1 LD3/4/5/6 ON or OFF 2 LD3/6 blinking Connect a second USB type A to Micro-B cable between CN2 and the PC, then observe the mouse cursor moving according to the board movement. Standard mouse 3 LD3/4/5/6 ON or OFF The LEDs will light up according to the position of the user’s fingertip on the linear touch sensor. Linear sensor Four LEDs LD3, LD4, LD5,LD6 are blinking LEDs blinking The four LEDs will indicate the board movement. MEMS sensor The following is the detailed procedure and description of each function. Function 0: When connecting the STM32F072 Discovery board to a PC, the LEDs LD1 (COM) and LD2 (PWR) will light up and four LEDs LD3, LD4, LD5, LD6 are blinking. Function 1: Press the User button B1 to enable the gyroscope MEMS sensor (L3GD20). The four LEDs will indicate the board motion, direction and speed. Function 2: Connect STM32F072 Discovery board to a PC with a 'USB type A to Micro-B' cable through USB connector CN2 (USB USER). This converts the board to a standard mouse. Press User button to start the USB test. Move the STM32F072 Discovery board and see the mouse move according to the board movement. Function 3: Press the User button again to enable the linear touch sensor; the four LEDs will be ON or Off according to the position of the fingertip on the linear touch sensor.

A set of examples for each peripheral are ready to be run. 2.2 Programming firmware application 2.2.1 IDE requirements To start programming, user must: Install the preferred Integrated Development Environment (IDE). Install the ST-LINK/V2 driver from the ST web site. Note: Required information to download and install desired IDE and ST-LINK/V2 are detailed in Getting started with STM32F072 Discovery software development tools. 2.2.2 Programming application Several IP examples are provided with the firmware package (see Figure 3) under STM32F072B-Discovery_FW_VX.Y.Z /Projects/ and the user must use one of the three tool chains supported to program applications on the STM32F072B-DISCO board. To program the Template example, follow the sequence below: 1. Open application folder STM32F072B-Discovery_FW_VX.Y.Z /Projects/Template. 2. Select the desired IDE project (EWARM for IAR, MDK-ARM for Keil or TrueSTUDIO for Atollic). 3. Double click on the project file (for example, Template.eww for EWARM). 4. Rebuild all files: Project->Rebuild all. 5. Load project image: Project->Debug. 6. Run program: Debug->Go. The demo software, as well as other software examples that allow you to discover the STM32 F0 series features, are available at www.st.com/stm32f0-discovery.
