Every engineering office using microcontrollers should be able to do this for you - it is a "just to do thing", nothing special. It's a standard problem to design special keyboards for devices, e.g. plastic foil keyboards. But for your application you should use single keys, because they are more tactile and durable. Anyway - did you think of keyboard beeps for distinguish blind keypressing? This is also a thing, a microcontroller could do for you (okay, much sophisticated). And regarding to the software development company - selling own hardware saves a dongle. ;o) > Do you know whether there are better ways to > do it, maybe with a direct USB driver and an API that makes it more > "direct" to use the key presses? Most of the USB solutions create a virtual RS232 port for communication to software. Also the Arduino does - there is a usb connection, but you can access it as a serial device. _______________________________________________ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
