## Required Hardware:

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

### Configuration 1: Explorer 16

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

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: 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.

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 – Data Logger” 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:

Once the device is programmed with the correct firmware, connect a serial cable from the Explorer 16 to the computer. Open up a terminal program with the following settings: baud rate – 57600, data – 8bit, parity – none, stop – 1 bit, and flow control – none.

Connect power to the Explorer 16. If power was already connected to the board before the serial port was connected, either cycle power, press reset, or press enter. This should give a “>” prompt. If the prompt does not appear then verify that you programmed the firmware correctly and that you have the correct serial port settings.

Type “HELP” in the prompt for a list of the available commands.

For more information, please refer to the embedded host help file located in the "<Install Directory>\Microchip\Help" directory.

Note: when bootloading this application using the HID bootloader, please make sure that the “Allow Configuration Word Programming” box is checked. This is required to be able to program the interrupt vectors on PIC24 products. As this demo requires interrupts it will not work without this feature enabled.
