## Required Hardware:

To run this project, you will need one of the following sets of hardware:

### Configuration 1: PIC18F87J50 PIM

PIC18F87J50 Plug-In-Module (PIM) (MA180021)

High pin count (HPC) Explorer (DM183022)

SD Card PICTail™ Plus Daughter Card (AC164122)

### Configuration 2: Explorer 16

Explorer 16 (DM240001)

USB PICtail™ Plus Daughter Card (AC164131)

And one of the following PIMs

PIC24FJ256GB110 Plug-In-Module (PIM) (MA240014)

PIC32MX USB Plug-In-Module (PIM) (MA320002)

### Configuration 3: PIC24F Starter Kit 1

PIC24F Starter Kit 1 (DM240011)

### Configuration 4: PIC18F46J50 Full Speed USB Demo Board

PIC18F46J50 Full Speed USB Demo Board

## Configuring the Hardware:

This section describes how to set up the various configurations of hardware to run this demo.

Configuration 1: PIC18F87J50 PIM

Configuration 2: Explorer 16

Configuration 3: PIC24F Starter Kit 1

Configuration 4: PIC18F46J50 Full Speed USB Demo Board

### Configuration 1: PIC18F87J50 PIM

1) Short JP4 on the PIC18F87J50 PIM. This allows the demo board to be powered through bus power.

2) Short JP1 such that the “R” and “U” options are shorted.

### Configuration 2: Explorer 16

1) Before attaching the PIM to the Explorer 16 board, insure that the processor selector switch (S2) is in the “PIM” position as seen in the image below.

2) Short the J7 jumper to the “PIC24” setting

3) Before connecting the PIM to the Explorer 16 board, remove all attached cables from both boards. Connect the PIM to the Explorer 16 board. Be careful when connecting the boards to insure that no pins are bent or damaged during the process. Also insure that the PIM is not shifted in any direction and that all of the headers are properly aligned.

4) On the USB PICTail Plus board, short jumper JP1. Remove all other shorts on the board.

5) Connect the USB PICTail Plus board to either of the female PICTail Plus connectors or on the card edge connector (J9) at the edge of the Explorer 16 board.

Note: When using the HID bootloader for PIC32, it is important to modify the procdefs.ld file to relocate the sections of code that will hold the bootloader and those sections that will hold the user application. Example modified procdefs.ld files have been provided with each project. This file is currently names “Procdefs.ld.boot”. When using the example project with the bootloader it is required to remove the “.boot” section of the file. This will allow MPLAB to use this file instead of the default linker file. Once the linker file is renamed, however, the project will no longer work without the bootloader. Please rename the file in order to get the project working again with PIC32.

### Configuration 3: PIC24F Starter Kit 1

The PIC24F Starter Kit does not require any hardware setup to run this demo. This demo does, however, require the user to change the default selected device in the project before compiling the demo.

1) Open the associated project file for C30

2) In MPLAB Select “Configure->Select Device”

3) In the device list box in the top left corner of that window, select “PIC24FJ256GB106”

### Configuration 4: PIC18F46J50 Full Speed USB Demo Board

1) Short JP3 to allow the board to be powered from the USB.

Firmware:

To run this project, you will need to load the corresponding firmware into the devices. There are two methods available for loading the demos: Precompiled demos and source code projects.

Precompiled Demos are available in the “<Install Directory>\USB – Precompiled Demos” folders. Each demo should be prefaced with the hardware platform it is compiled for. Select the file that matches the hardware that you have and the demo that you want to run. For more information about how to load a precompiled project, please see the “Getting Started – Loading a precompiled demo” guide.

The source code for this demo is available in the “<Install Directory\USB Device – Mass Storage – Internal Flash” directory. In this directory you will find all of the user level source and header files as well as project and workspace files for each of the hardware platforms. Find the project (*.mcp) or workspace (*.mcw) file that corresponds to the hardware platform you wish to test. Compile and program the demo code into the hardware platform. For more help on how to compile and program projects, please refer to the MPLAB® IDE help available through the help menu of MPLAB (Help->Topics…->MPLAB IDE).

Please note that when using either the C30 or C32 demo projects you will be required to select the correct processor for the demo board.

1) Open the associated project file

2) In MPLAB Select “Configure->Select Device”

3) In the device list box in the top left corner of that window, select the desired device.

Running the Demo:

This demo uses the selected hardware platform as an drive on the computer using the internal flash of the device as the drive storage media. Connect the hardware platform to a computer through a USB cable.

The device should appear as a new drive on the computer named “Drive Name”. The volume label or file information can be changed in the Files.c file located in the project directory.
