Quick start UM1733

6/11 DocID025933 Rev 1

2 Quick start

The STM32F334 Discovery kit demonstration software is already preloaded in the Flash

memory on the board. The latest versions of the source code and associated

documentation can be downloaded from www.st.com/stm32f3-discovery.

The following sections include step-by-step how to start using the STM32F334 Discovery

board demonstration software.

2.1 Hardware requirements

The requirements to configure the STM32F334 Discovery board and start with the

demonstration software are as follows:

•One 'USB type A to Mini-B' cable to power up the STM32F334 Discovery board from

the USB ST-LINK (USB connector CN1)

•Check jumper positions on the board

– CN3 ON (Discovery mode).

– JP3 (Idd) ON

UM1733 Quick start

2.2 Running the pre-loaded demonstration software

Follow the sequence below to launch the pre-loaded demonstration application:

1. Connect the STM32F334 Discovery board (connector CN1) to a PC using the USB-

type-A to Mini-B cable to power the board. The red LED LD1 (PWR) and LD3 (COM)

light up, and fours LEDs (LD3, LD4, LD5 and LD6) blink continuously until button B1 is

pressed.

2. Each click on user button B1 changes the executed function, follow the sequence

below (Function1 to Function4) to launch the demo application:

3 Firmware package

To get started with the STM32F334 Discovery kit, a firmware package that contain a set of

IPs examples and demonstration of some features are available at www.st.com/stm32f3-

discovery.

3.1 Package description

The STM32F334 Discovery firmware applications and related documentations are provided

in one single package and supplied in one single zip file. The extraction of the zip file

generates one folder, STM32F3348-Discovery_FW_VX.Y.Z, which contains the following

subfolders:

Figure 3. Firmware Package contents

Libraries folder:

•CMSIS subfolder: Cortex-M4 CMSIS files

•STM32F30x_StdPeriph_Driver subfolder: standard peripherals drivers

Project folder:

•Demonstration subfolder: firmware of preloaded demo

•Master_Workspace subfolder: common project for all examples

•Peripheral_Examples subfolder: examples ready to run

•Template subfolder: pre-configured project templates

Utilities folder:

•STM32F3348-Discovery subfolder: for the abstraction layer of the supported board

3.2 Programming firmware application

3.2.1 IDE requirements

To start programming, user must:

•Install the preferred Integrated Development Environment (IDE).

•Install the ST-LINK/V2-1 driver from the ST web site.

Note: Required information to download and install desired IDE and ST-LINK/V2-1 are detailed in

Getting started with STM32F334 Discovery software development tools.

3.2.2 Programming application

Several IP examples are provided with the firmware package (see Figure 3) under

STM32F3348-Discovery_FW_VX.Y.Z /Projects/ and the user must use one of the three tool

chains supported to program applications on the STM32F3348-DISCO board.

To program application the Template example, follow the sequence below:

1. Open application folder STM32F3348-Discovery_FW_VX.Y.Z /Projects/Template.

2. Select the desired IDE project (EWARM for IAR, MDK-ARM for Keil or TrueSTUDIO for

Attolic)

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

STM32F3 series features are available at www.st.com/stm32f3-discovery.
