Programming

Designing Graphical User Interface

Duration: 1 Hour
Location: Online
Prerequisite: Completion of the Advanced course

The Programming course builds on all topics taught in Intermediate and Advanced course. The AVSnap coordinator will introduce User Interface design concepts with practical application.

During the course a small control system with full Graphical User Interface (GUI) will be designed and programmed. The AVSnap uses internal programming language modeled after Pascal language. It is event driven with powerful user interface.

Additional information will be provided on RS-232 and TCP communication design and control of other equipment. To participate in this course you should have active RS-232 port. If you computer does not have RS-232 port, then simulated port will be created to complete exercises.
