APPLICATION NOTE

DATA LOGGING PROGRAM FOR TESTING

ST7 APPLICATIONS VIA ICC

by Microcontroller Division Application Team

INTRODUCTION

Data logging is the process of recording data. It is required during the course of application de-

velopment in order to test application robustness and reliability.

The purpose of this application note is to show how to implement a data logging system based

Over a specified time period, the data logging system records each and every value of a par-

ticular variable or register used by the application. The advantage of using this ICC-based

data logging package is that your application runs on the ST7 in its target environment, with

the same hardware configuration and settings and with minimal added software.

An ST7 application software example and the PC side executable are provided with this appli-

between a PC-based data logging system and the user application. It can be used for ST7 de-

vices supported by the STICK, i.e. ST7 devices supporting ICC protocol except the USB family

devices. The ST7 software provided is an example which can be modified and used, or a com-

pletely new software may be developed by the user.

an external controller such as a flash programmer or in-circuit debugger. It is described in de-

tail in the ST7 ICC Protocol Reference Manual.
