STM32100E-EVAL demonstration firmware

Introduction

This user manual describes the demonstration firmware running on the STM32100E-EVAL evaluation board, which can be used to evaluate the capabilities of the high-density value line STM32F100ZET6 microcontroller and on-board peripherals.

This demo contains many applications that can be easily reused, such as RTC calendar, file system FAT implementation on SD Card, Waveplayer with STM32 DAC peripheral, HDMI

CEC networking demo with an infrared remote control capability, temperature sensor interfacing and TFT LCD with touch screen.

The STM32100E-EVAL board is delivered with the demonstration programmed in the internal Flash memory, and all the files needed by the demonstration are programmed in the

MicroSD card. At each reset (board power-up, external reset, etc.), the demonstration is executed.

In case the STM32100E-EVAL board was not factory-programmed or the demonstration application was erased, the in-circuit programming (ICP) boot loader can be used to program this file. For more details, refer to

Section 3: STM32100E-EVAL demonstration package

and

Section 4: STM32100E-EVAL demonstration programming

.

This demonstration firmware is available for download from the STMicroelectronics website: www.st.com

2.6.5 External memory organization

The STM32100E-EVAL demonstration is based on an embedded free FAT file system,

DosFs

(a)

. The file system is needed to read all media information from the on-board

MicroSD memory card.

20/49 a. The DosFs is a FAT-compatible filesystem intended for fairly low-end embedded applications. It is not the leanest possible implementation (the leanest FAT implementations operate in << 512 bytes of RAM, with heavy restrictions). This code strikes a good balance between size and functionality, with an emphasis on RAM footprint. For more details, refer to the following link http://www.larwe.com/zws/products/dosfs/index.html.

Doc ID 18064 Rev 1

UM1011 Running the demonstration

The SD Card memory is organized in two subdirectories:

● STFILES: this folder contains all required demo media files (icons, wave and slides).

User files located in this folder cannot be handled by the demonstration; only default files are managed. The STFILES directory and its internal files are mandatory for demonstration startup.

● USER: this is a user folder. You can add here your 16-bit bitmap images (320x240) and waves. This folder is used only by the Image Viewer and Wave Player submenus. For

more details on the different files properties, please refer to Section 2.7.3: Image

2.7.2 Calendar

Note:

The STM32F100ZET6 features a real-time clock (RTC) that provides a set of continuously running counters. These can be used, with suitable software, to implement a clock-calendar function. The counter values can be written to set the current time of the system.

This submenu is used to configure the time, date and alarm. The date, time and alarm settings are not lost when the board is powered off owing to the battery connected to the

V

BAT

pin. The V

BAT

pin supplies power to the RTC unit, allowing the RTC to operate even when the main digital supply (V

DD

) is turned off.

To be able to use the battery to back up the RTC, the JP1 jumper must be in the position

Battery-VDD on the STM32100E-EVAL board.

In any submenu, if the time and date parameters have not yet been configured, the message shown in

The temperature variations can be monitored easily using the STM32 I2C SMBus feature.

This is managed by the SMBus Alert, which generates a dedicated interrupt to inform the system that the temperature is out of the selected range. This can be very useful for systems where the increase of temperature needs an immediate intervention, like in motor control, medical systems, etc.

If the temperature exceeds the over-limit high value (TEMPERATURE_TOS: Over Limit

Temperature), the SMBus Alert interrupt is generated and the following warning message is displayed on the LCD screen:
