GAMBAS BOOK 3.19.1

The examples presented are taken from self-developed and tested demonstration programmes from different chapters. Only the source code sections are given, with which the implementation of the above concept becomes visible. You will find the archives for the complete project in the download area.

Admittedly - the display is a bit unfamiliar; but has its charm when, after some practice, you can immediately grasp and announce the time of 14:09:24:

This stopwatch is designed to provide convenient end and split times for specific sequences. In addition to the start and stop buttons, there is also a pause button (the display is not updated) and a continue button that switches the display back on.
