Recently I've installed a software device driver for a device that connects to my local machine via USB. How do I communicate with the device? Do I communicate directly with the installed software device driver?

Tools:

  • OneTouch Ultra 2 glucometer
  • Windows XP
  • Meter Drivers for OneTouch(R) Software v1.12.0.0
  • Custom Communication Protocols

  • What kind of device? On what kind of operation system? What API does the driver provide? – A.H. Jul 22 '12 at 13:26
  • The protocol does not matter in the first place. The _transport_ matters. In the simplest case the driver just installs a virtual serial COM port. This can be opened like any other serial device with Java. THEN the protocol can be implemented in Java.
    But with so little information about the specific device, driver and available APIs you will NOT get any usefull information.     – A.H. Jul 22 '12 at 13:30

    The writers of the device driver usually define how to communicate with it. – Peter Lawrey Jul 22 '12 at 16:05
  • it suggests using `HyperTerminal` to shell out commands...not sure if i like that approach...looking to potentially either Java wrap that, or write my own java `HyperTerminal`.. – user1329572 Jul 22 '12 at 17:17

You would have to use JNI to access the underlying OS. Standard Java provides no hooks into the OS at that level in pure Java.

The company offers both a "meter driver" and "communication protocols". If you're wanting to write your own software to communicate with the meter, I'd fill out the form on http://www.onetouch.com/software_kit and see what that has to offer.
