SOFTWARE OVERVIEW
Chapter 3. Using the Demo Tool Application
The items discussed in this chapter are:
• Software Overview
• Starting the Program
• Demo mode
• Bootload mode
The PICDEM FS USB Demo Tool (more simply, PDFSUSB or the “Demo Tool”) is a
Windows operating system-based software application designed to be used with the
PICDEM FS USB board for evaluating some of Microchip’s full-speed USB solutions.
Using this software, you can evaluate USB features and performance offered by the
PIC18F4550 microcontroller.
There are two modes available: Demo mode and Bootload mode. Demo mode demon-
strates communication to and from the host PC through USB in a typical embedded
system setup. The application shown includes data logging, real-time sensing, and how
to use the PC to control peripheral components. Bootload mode allows designers to
download and evaluate a different firmware program without using an additional
external programmer.
The Demo and Bootloader modes are two separate firmware applications. Both
programs are totally separate and do not share any USB functions or descriptors. The
bootloader code is write-protected and cannot be overwritten by firmware. An external
programmer, such as MPLAB ICD 2, is required to erase the bootloader. The two pro-
grams also have different USB product IDs (but the same Vendor ID). For reference,
the product IDs are:
• Bootload: VID 0x04D8, PID 0x000B
• Demo: VID 0x04D8, PID 0x000C
Note:
Because the demo and bootloader are two different applications, they are
treated as two devices. The Microchip USB driver will attempt to install
when each of the applications is launched for the first time. In the procedure
described for the previous chapter, the USB driver for the demo application
was installed. The driver for the bootload application will begin installation
on its first launch.
