PICDEM FS USB BOARD HARDWARE FEATURES
™
The software consists of the Microchip General Purpose USB Windows operating
system driver, mchpusb.sys, which allows a PC application to communicate directly
with the device’s endpoints. A set of user-friendly programming interfaces, the
MPUSBAPI Library, is also provided to allow easy application development.
The board comes preprogrammed with a default demo application and is ready for
evaluation right out of the box. New programs can be downloaded to the PIC18F4550
microcontroller using a preprogrammed bootloader via the USB interface. A PC-based
application, the PICDEM FS USB Demo Tool, facilitates the bootloading process and
serves as the host application in the default demonstration.
1.3.1
The PICDEM FS USB demonstration board provides two simple advantages:
A READY-TO-USE DEMONSTRATION: As delivered, the board is ready for full-speed
USB operation; all that is required is the proper driver (included) and the Demo Tool
application. Users can also reprogram the board with different applications, included on
the Starter Kit CD, to evaluate other USB solutions that can be tailored to their needs.
AN EXPANDABLE PLATFORM: Users can also expand the hardware capabilities of
the board through its expansion headers, and even interface it with available PICtail™
demonstration and evaluation daughter boards.
The overall layout of the board is shown in Figure 1-1, with a list of the main features
following. The more complex features are discussed in detail later in this section.
FIGURE 1-1:
1. Microcontroller: The 44-pin TQFP PIC18F4550 microcontroller (U2) is the
2. ICE Interface Riser: The microcontroller is surrounded by a 44-pin pad (U5),
heart of the demonstration board, and provides all USB functionality on one chip.
Refer to the device data sheet (DS39632) for a complete discussion of the
microcontroller and its feature set.
arranged as four groups of 11 on each side. These locations can be used to mount
a riser for interfacing with Microchip’s MPLAB ICE 2000/4000 emulator system.
