## Required Hardware:

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

### Configuration 1: PICDEM FS USB

PICDEM FS USB (DM163025)

### Configuration 2: PIC18F87J50 PIM + HPC Explorer

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

### Configuration 3: Explorer 16

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

Explorer 16 (DM240001)

USB PICtail™ Plus Daughter Card (AC164131)

### Configuration 4: Low Pin Count USB Development Kit

Low Pin Count USB Development Kit with PICKit 2 Debugger/Programmer (DV164126) or without Debugger/Programmer (DM164127)

## Configuring the Hardware:

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

Configuration 1: PICDEM FS USB

Configuration 2: PIC18F87J50 PIM + HPC Explorer

Configuration 3: PIC24FJ256GB110 PIM + Explorer 16

Configuration 4: Low Pin Count USB Development Kit

### Configuration 1: PICDEM FS USB

1) If using the PICDEM FS USB Demo Board, no hardware related configuration or jumper setting changes should be necessary. The demo board need only be programmed with appropriate firmware.

### Configuration 2: 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 3: Explorer 16

1) Before attaching the PIC24FJ256GB110 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 PIC24FJ256GB110 PIM to the Explorer 16 board, remove all attached cables from both boards. Connect the PIC24FJ256GB110 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.

### Configuration 4: Low Pin Count USB Development Kit

1) Short pins 2 and 3 of J14

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 – HID - Keyboard” 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 IDE (Help->Topics…->MPLAB IDE).

Running the Demo:

This demo uses the selected hardware platform as a USB keyboard. Before pressing the button, select a window in which it is safe to type text freely. Pressing the button will cause the device to print a character on the screen.
