  1. Creating a Virtual Control Console for Hardware using Visual Basic Presented by William Koch Kochworx, Ltd. October 24, 2002

  2. Summary • Goals • Hardware & Interface • Visual Basic Concepts • Solution Development • Demonstration

  3. Goals • Create a Virtual Console to Demonstrate Hardware • Describe Visual Basic Concepts • Use the RS-232 Port

  4. Hardware & Interface • Virtual Hardware – the RGB Beast • 4 Addressable Channels • Each Channel has 0-FF settings for Red, Green, Blue • Settings Tx Via RS-232 Interface • Start Sequence = 4 $FF • Data Sequence = Channel# R G B • Sample: FF FF FF FF 01 C0 FF D6

  5. RGB Beast Virtuware

  6. Software to Hardware Connection

  7. Visual Basic Concepts • Basis of all Visual Tools is Object Oriented Design • Functionality is Encapsulated in Controls • Properties, Methods & Events provide programming hooks • VB is powerful because of Reusable Components

  8. Solution Development • Begin a Project as a Standard EXE • Add Controls for Project to the Toolbox (ex. MSCOMM Control 6.0) • Design the Form Visually by Adding Controls and Setting Properties • Write Code to Interact with Visual Objects

  9. Constructing Virtual Console • Add a Label and a Slider Control to Form • Set Slider Properties, Label Properties • Replicate for Blue, Green • Add a Timer, MSCOMM Control • Write Code to Transmit Data

  10. Simple Control Console

  11. Coding the Timer • Must send 4 FF’s, Channel#, R, G, B • When Byte Stream Ready, Send • Timers specified in milliseconds • Finest granularity is ~55ms, max is 65535ms (60K=1 minute)

  12. Adding a Channel Selector • Textbox • Spinner Control • Command Buttons • Radio Buttons • …many options available • Hook the Channel Selector Into Data Stream

  13. Other Visual Controls • Microsoft Standard Controls • 3rd Party Controls for just about anything

  14. Summary • Goal was to create a Virtual Console to control a hardware device • Hardware was a 4-Channel addressable RGB display device • VB Components encapsulate large amounts of functionality • Drag/Drop Development of UI • Demonstrated Hardware Control
