I want a 16 bit parallel input to a circuit from my computer, but I can't afford to buy enough USB interface boards as I'm going to be repeating the project a couple of times.
Is it possible to use a single PIC chip to take in a signal from a USB port on the computer and output the 16bit parallel data.
Going to the computer end - is it possible to manipulate signals from the USB port. It's really convenient when a load of DLLs come with USB interface boards. I'm proficient in both Delphi and C++.
Don't know, but all my computers have them, though my printers don't. If you don't have one, you can add it for less than a tenner. It makes I/O programming very easy. But you will need to download and install a very simple DLL.
You know, you can always use one of those USB to parallel cables, and when the driver (the accompanying disc) is installed, you can write your program as if you were dealing with any parallel port! both I/O!
