With the phasing out of game, serial and parallel ports from modern computers and the ever increasing popularity of USB, it makes sense that hobbyists start getting to grips working with USB. Unfortunately, USB is not a simple protocol and can be daunting to implement. Luckily, there are several solutions on the market that can make implementing a USB device much easier.
This project focuses on the use of a USB PIC and the mikroC compiler to convert an old game port joystick to utilize USB. One of the advantages of the mikroC compiler are the built USB HID libraries that make creating a USB HID device a doddle. When writing USB code using the mikroC compiler, the USB device produced is a generic HID device that can be used to transfer data to and from the PIC. However, it is possible to modify the USB descriptor generated by mikroC so that it produces a specific USB HID device, like a keyboard, mouse, joystick or graphics tablet.
