Introduction
The gameport to USB translator is a simple example that reads a PC game-
towards a successful start with USB. These examples range from the very
basic gameport translator, to a very specialized LCD display. The gameport
and PS/2 examples are excellent tools to use, in order to become more famil-
iar with report descriptors and basic USB communications. These basic
examples are extremely useful because the OS vendor has already written
generic Human Interface Device (HID) drivers. The LCD display example
does not have a generic PC driver. In this example, PC software has been
provided to demonstrate how you can develop your own PC applications to
interface to your device. Example code is provided for PC and Macintosh.
port and reports the information over USB. Since peripherals for gameports
come in all shapes and sizes, it is important to identify exactly what peripheral
is used, in this example -- the Dexxa
can be used, however, some change to the firmware functions may be
required. The example code will enumerate as a gamepad with 2 axis and 6
buttons. PORTA on the PICmicro MCU is used to read the analog voltages
from resistors in the direction pad (D-pad) and two of the buttons, while
PORTD reads the switches for the four remaining buttons. Refer to
Figure 2.1.
