## Required Hardware:

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

### Configuration: Explorer 16

Explorer 16 (DM240001)

USB PICtail™ Plus Daughter Card (AC164131)

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

## Configuring the Hardware:

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

Configuration: PIC24FJ256GB110 PIM + Explorer 16

### Configuration: 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 SD Card PICTail Plus board, short JP1, JP2, and JP3 on the side farthest from the SD Card holder. Depending on the revision of the board you have the silk-screen on the board may incorrectly label the top as the “HPC-EXP” setting. Please ignore this silk screen and place the jumpers as described above and seen below.

5) Connect the SD Card PICTail Plus board to the HPC Explorer board in either the female PICTail Plus connectors. Attach the board in the top bay of either of the connectors.

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

7) 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.

Firmware:

To run this project, you will need to load the corresponding firmware into the device. 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_msd_device_demo” directory. In this directory you will find all of the user level source and header files as well as project and workspace files. Find the project (*.mcp) or workspace (*.mcw) file. 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).

Running the Demo:

This demo uses the hardware platform as an SD card reader. Connect the hardware platform to a computer through a USB cable.

The device should appear as a new drive on the computer named “Removable Drive”.

If no SD Card is inserted in the SD Card PICTail Plus, the following dialog will pop-up.

Once a compatible card is inserted in the card reader, files can be read, deleted, and manipulated like any other drive on the computer.
