To run this project, you will need one of the
following sets of hardware:
PIC18F87J50
Plug-In-Module (PIM) (MA180021)
Explorer
16 (DM240001)
USB
PICtail™ Plus Daughter Card (AC164131)
And one of the following PIMs
PIC24FJ64GB004
Plug-In-Module (PIM) (MA240019)
PIC24FJ256GB110 Plug-In-Module (PIM) (MA240014)
PIC32MX USB Plug-In-Module (PIM) (MA320002)
dsPIC33EP512MU810 USB Plug-In-Module (PIM)
PIC24EP512GU810 USB Plug-In-Module (PIM)
PIC18F46J50
Full Speed USB Demo Board (MA180024)
PIC32 USB Starter Board (DM320003)
This
section describes how to set up the various configurations of hardware to run
this demo.
Configuration 1: PIC18F87J50 PIM
Configuration 3: PIC18F46J50 Full Speed USB Demo Board
Configuration 4: PIC32 USB Starter Board
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.
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.
1) Short JP3 to allow the board to
be powered from the USB.
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.
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.
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.
