This converted Tandy Deluxe Joystick is now
usable as a USB Human Interface Device.
Caution:
The Wixel’s I/O lines are not 5V tolerant. You must use level-shifters, diodes, or voltage dividers
to connect the Wixel to outputs from 5V systems. Also, avoid drawing more current from an I/O line than
it can provide (see the discussion of P1_0 and P1_1 in
). Avoid connecting multiple output pins
together.

9.g. Joystick App
Overview
This app allows a Wixel connected to a computer to be
used as a joystick. Readings from the Wixel’s analog and
digital input pins can represent up to six analog axes and
16 digital buttons or switches. The Wixel appears to the
computer as a standard USB Human Interface Device
(HID); after the Wixel has been configured, no driver
installation is necessary to use the joystick. With a Wixel
running the Joystick App, you can easily build a custom
USB input device or convert an existing device into a USB
peripheral,
as
shows.
