Configuring the Hardware:

 

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

Configuration 1: PIC18F87J50 PIM

Configuration 2: Explorer 16

Configuration 3: PIC18F46J50 Full Speed USB Demo Board

Configuration 4: PIC32 USB Starter Board

 

 

          Configuration 1: 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 2: 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 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.

 

            3a)  If using the PIC24FJ64GB004 PIM, please insure that the programming port switch is switched in the PGX1 direction.

 

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.

 

Note: When using the HID bootloader for PIC32, it is important to modify the procdefs.ld file to relocate the sections of code that will hold the bootloader and those sections that will hold the user application.  Example modified procdefs.ld files have been provided with each project.  This file is currently named “Procdefs.ld.boot”.  When using the example project with the bootloader it is required to remove the “.boot” section of the file.  This will allow MPLAB to use this file instead of the default linker file.  Once the linker file is renamed, however, the project will no longer work without the bootloader.  Please rename the file in order to get the project working again with PIC32.

 

Configuration 3: PIC18F46J50 Full Speed USB Demo Board

            1) Short JP3 to allow the board to be powered from the USB.

           

 

Configuration 4: PIC32 USB Starter Board

No specific hardware configuration is required for this demo. Use the OTG cable provided with the starter kit to connect OTG connector J5 (on the bottom side of the starter kit) to the PC.

 

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 – Composite – HID + MSD” 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 (Help->Topics…->MPLAB IDE).

 

Please note that when using either the C30 or C32 demo projects you will be required to select the correct processor for the demo board.

1) Open the associated project file

            2) In MPLAB Select “Configure->Select Device”

            3) In the device list box in the top left corner of that window, select the desired device.

 

 

Running the Demo:

This demo uses the selected hardware platform as both a flash drive using the internal flash as storage and a custom HID device.  It will appear to the computer as if two USB devices were attached. 

 

For details how to run the demo for each of the functions please see the respective getting started documents: “USB Device – Mass Storage – Internal Flash” and “USB Device – HID – Simple Custom Demo”.

 

NOTE: the “USB Device – HID – Simple Custom Demo” application is expecting a PID of 0x003F.  Because these two different applications can’t have the same PID, this demo uses PID 0x0054.  The PC application that corresponds to this application is only looking for devices with PID 0x003F so the PC application will not be able connect to this demo without modification.  Modify the MY_DEVICE_ID field to "Vid_04d8&Pid_0054" and recompile

 

Also please note that for the PIC24F Starter Kit 1 the pushbutton functionality is not implemented.
