Overview

inDART-ST7 Series In-Circuit Debuggers are powerful entry-level tools for

STMicroelectronics ST7-based systems. inDART-ST7 Series In-Circuit Debuggers take

advantage of STMicroelectronics’ STVD7 (STMicroelectronics Visual Debug) Integrated

Development Environment and the ISP (In Situ Programming) feature to program the

FLASH memory of the ST7 family of microcontrollers. Together with STVD7, inDART-

ST7 Series In-Circuit Debuggers provide you with everything you need to write, compile,

download, in-circuit emulate and

debug user code. Full speed program

execution allows you to perform

hardware and software testing in real

time. inDART-ST7 Series In-Circuit

Debuggers are connected to the host

PC through a parallel port, while the

10-pin probe of the debuggers fits

into the target’s standard ISP

connector.

STVD7 Integrated

Development Environment

The inDART-ST7 user interface

(common for all of the inDART-ST7

Series In-Circuit Debuggers) is based

on the ST7 Visual Debug Integrated

Development Environment (STVD7).

STVD7 enables programs to be executed and stopped where desired, while viewing the

memory contents. It offers the ability to step through and examine code at the C source

level and the Assembly instruction level. You can introduce breakpoints and run or

single-step the executable, while viewing the source and

observing current program values. All registers and memory

locations are accessible for both read and write operations.

Demo Boards

On Design Kits packages, a full-featured experiment board

for a specific ST7 microcontroller is also included. Each

demo board includes DIP-switches, jumpers, LEDs,

push-buttons, a potentiometer, prototyping area and a

standard ISP connector and can be used for evaluation/

experiments in the absence of a target application board.

What is In Situ Programming (ISP)?

The ISP feature allows you to update the content of

FLASH program memory when the chip is already

plugged on the application board. ISP programming

uses a serial protocol to interface a programming tool

like inDART. The ISP feature can be implemented with

a minimum number of added components and board

area impact. inDART-ST7 Series In-Circuit

Debuggers use the standard, 10-pin ST7 ISP

connector to program and in-circuit emulate the

target device.
