## Required Hardware:

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

### Configuration 1: Explorer 16

Explorer 16 (DM240001)

USB PICtail™ Plus Daughter Card (AC164131)

Graphics PICtail™ Plus Board with 3.2” Display kit (AC164127-3)

And one of the following PIMs

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

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

dsPIC33EP512MU810 Plug-In-Module (PIM)

PIC24EP512GU810 Plug-In-Module (PIM)

## Configuring the Hardware:

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

Configuration 1: PIC24FJ256GB110 PIM + Explorer 16

### Configuration 1: 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 jumpers JP2 and JP3. 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.

6) Configure the SSD`926 Board with the following settings: Set the “parallel” jumper setting set to 8-bit and set the “flash cs” to RD1. Leave the PEN_INT jumper open:

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/Host – Printer – Print Screen Demo” 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® help available through the help menu of MPLAB (Help->Topics…->MPLAB IDE).

Running the Demo:

The first step required before running this demo is to calibrate the touch screen. Touch screen calibration is done by holding the touch screen down and power cycling the board. This will bring you to the touch screen calibration screen.

Follow the instructions on the screen.

Once the touch screen calibration is complete, plug in a printer into the board and reset the board. If the following screen comes up, then the printer that was plugged in is not supported or there is no printer plugged in. Please plug in a printer and reset the demo.

If the printer is successfully loaded then the following screen should come up. You can then draw on the screen and press print. When you press print the attached printer should print exactly what is on the screen and clear the screen.
