## Required Hardware:

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

### Configuration 1: Explorer 16

PIC32MX460F512L Plug-In-Module (PIM) (MA320002)

Explorer 16 (DM240001)

USB PICtail™ Plus Daughter Card (AC164131)

## Configuring the Hardware:

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

Configuration 1: PIC32MX460F512L PIM + Explorer 16

### Configuration 1: Explorer 16

1) Before attaching the PIC32MX460F512L 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 PIC32MX460F512L PIM to the Explorer 16 board, remove all attached cables from both boards. Connect the PIC32MX460F512L 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.

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 Generic Host 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® help available through the help menu of MPLAB (Help->Topics…->MPLAB IDE).

Running the Demo:

This demo will require two Microchip devices to run. One will act as the USB host and the other will run the USB peripheral.

Program the peripheral with the firmware found in the “usb_generic_device_demo” folder. Program the host with the firmware found in the “usb_generic_device_demo” folder.

Power the host. The LCD screen should show the revision number of the device firmware. Plug in the peripheral device. The LCD screen should now update with the potentiometer and temperature data from the attached peripheral.
