User’s Manual

1. Introduction

Overview

The IDB -ST7FLITE2 Evaluation Board demonstrates the capabilities of
the ST7FLITE1/LITE2 FLASH microcontrolle rs. The IDB-ST7FLITE2
Evaluation Board can be used as a standalone application or with an
emulator system, such as inDART-STX, through an ISP connection.

Board Features

The IDB -ST7FLITE2 Evaluation Board has the following hardware
features:

2. Getting Started

Overview

The IDB -ST7FLITE2 Evaluation Board can be used in conjunction with a
ISP-based emulator/programmer, such as SofTec Microsystems’
inDART-STX In-Circuit Debugger/Programmer.

If you use the evaluation board with SofTec Microsystems’ inDART-STX,
a sample application is provided. The sample application configures the
A/D peripheral to convert on the A/D channel connected to the
potentiometer and displays the results on the LEDs.

You can use inDART-STX together with STMicroelectronics Visual
Debug (STVD7) to debug the application by, for example, execute the
program step by step and watching how the microcontroller registers
vary.

Preliminary Operations

Before to try out the sample application, you must verify that both the
inDART-STX and the evaluation board are correctly set up.

1. Ensure that inDART-STX is connected to the PC (via the USB cable)
and to the demo board (via the ISP connector).

2. Make sure that the “OSCILLATOR” jumpers on the demo board
select the “OSC_CLK on PB4” position (jumpers J4 and J7 inserted,
jumpers J5 and J6 removed).

3. Make sure that all of the “LED ENABLE” jumpers (J9) and the
“POTENTIOMETER ENABLE” jumper (J8) are inserted.

4. Make sure that the sample device is in the appropriate socket on the
board. Finally, power up the evaluation board. The power connector
accepts 9-12 V DC, 200-mA wall plug-in power supply with a 2.1 mm
pin and sleeve plug with positive in the center and sleeve as ground.
Upon powering up the board, the green “POWER” LED turns on.

Running the Sample Application

1. Run the STVD7 user interface.

2. From the STVD7 main menu, choose File > Open Workspace.
Select the “adc.wsp” workspace file that is located under the

“\Program Files\SofTec Microsystems\inDART­STX\ST7\STVD7\Samples\Asm\LITE2\Adc” directory. Click
“Open”.

3. The application has already been assembled and the executable file
generated. From the main menu, choose Debug > Start Debugging.

4. From the main menu, select Debug > Run. The program will be
executed in real -time. Please note that the “BUSY” LED on the
inDART-STX unit turns on.

5. By rotating the potentiometer on the demo board, you affect the
results of the A/D conversion, and the binary value of each
conversion is displayed on the LEDs.

6. When you want to stop the sample application, select Debug > Stop
Program from the STVD7 main menu.
