1 Introduction
Universal serial bus (USB) is a low cost, fast,
bidirectional, isochronous, dynamically attachable serial
interface consistent with the requirements of the PC
platform. It is widely used in the PC connection.
Freescale's 9S08JM series devices include JM60, JM32,
and their derivatives. These derivatives integrate a USB
device controller and help customers interconnect their
devices to PCs and/or any other devices with USB
On-The-Go (OTG) capability. Freescale provides CMX
USB stack software for these devices, which can be
freely downloaded at http://www.freescale.com
.This all
around USB solution makes 9S08JM devices easy to use,
and enables rapid time to market for products.
This application note gives an overview of USB and
9S08JM USB device controller. It shows you how to
integrate the CMX USB stack into a CodeWarrior project
with an HID joystick application.
