Access from Delphi to Pololu USB SDK

I need to control the Jrk 21v3 USB from Delphi 2007.
Does anyone have an interface file for that ?


I don’t know much about Delphi 2007, but here are a few things you could try:

  • Learn how to call functions in .NET assemblies from Delphi.
  • Learn how to use WinUSB from Delphi, and read the source code that comes with the Pololu USB SDK as a guide to USB protocol used by the jrk.
  • Instead of using the Pololu USB SDK, use the Jrk’s virtual COM port (specifically the Command Port). You can probably find some example code that tells you how to access a serial port using Delphi. This is probably the easiest option. This page that I found on Google looks useful: … rialio.htm
