PIC32MX USB Starter Board User’s Guide

2.5 USING THE PIC32MX USB STARTER BOARD OUT OF THE BOX

Install software (instructions in section 2.4) before connecting the board to the host PC. The PIC32MX USB Starter Board may be used directly from the box as a demonstration board for the PIC32MX device. The PIC32MX is preprogrammed with the classic “Simon Says” game ( device and is ready for immediate use.

2.5.1 How to Play the Game

When the USB debug cable is plugged into the starter board’s Mini-B (debug) receptacle, the three LEDs start blinking to indicate the start of a new game. Begin the game by pressing one of the switches, SW1-SW3, to choose the level of game difficulty . SW3 is the easiest, SW1 is the hardest. The goal is to imitate the light patterns as long as you can, without getting frazzled. Ultimately, you will make a mistake and all of the LEDs will light up to signal the end of the game. After a brief pause, you can press any switch to start a new game.

If you launch MPLAB IDE and connect to the starter board while the game is running, the game will stop. Further, if you perform a debug or program operation from MPLAB IDE, the demo application will be replaced with the current MPLAB project application. However, the game can be reloaded onto the starter board by opening the file

simon_says_demo.mcw from c:\Program Files\Microchip\pic32_solutions\ simon_says_demo

The preprogrammed example code on the PIC32MX has been included in the PIC32MX USB Starter Board demo-projects download file located at the following URL:

http://www.microchip.com/PIC32USBboard. All project files have been included, so

that the code may be used directly to restore a PIC32MX to its original state (i.e., if the sample device has been reprogrammed with another program), or so you can use the tutorial code as a platform for further experimentation.

2.10 TUTORIAL PROGRAM OPE R AT I O N

The USB Human Interface Device (HID) mouse tutorial project demonstrates a simple USB peripheral device by emulating a mouse. Depending on the revision of your USB starter board, make the following connections to run the mouse demo.

• For Rev B of the USB starter board, the host PC must have two available USB

ports:

1. Mo ve jum per JP2 to the open posi tio n.

2. Use the USB debug cable (Mini-B to A) to attach the board’s debug connector J1 to the first USB port of the host PC. Rev B boards source power from the debugger connection.

3. Use the USB Micro-B to full-sized A cable to attach the board’s J5 connector (type Micro-AB receptacle) to the second USB port of the host PC.

• For a later revision of the USB starter board:

1. Mo ve jum per JP2 to the open posi tio n.

2. Use the USB Micro-B to full-sized A USB cable to attach the board’s J5 connector (type Micro-AB receptacle) to an available USB port on the host PC.

Note: For the HID mouse demo (and all other USB device demos), the JP2

jumper should be open to prevent the possibility of back-feeding voltage onto VBus from one port on the host to another (or from one host to another).

After a pause, the PIC32MX USB Starter Board will enumerate as a standard mouse HID, using dr iver s bui lt in to th e host ’ s ope rati ng sy stem. The su cces sfu l compl eti on o f this process is usually accompanied by a “bing-bong” tone from the host PC. The output window will display a message indicating that the demo is running, as shown in Figure 2-7.

PIC32MX USB Starter Board Tutorial

• USB bus power connected to USB debug connector J1.

• USB bus power connected to PIC32 USB connector J5 – if using Rev C or later

revision of the board.

• An external application board with a regulated DC power supply that provides +5V

can be connected to the J2 application board connector that is provided on the bottom side of the board.

One green LED (D3) is provided to show that the PIC32 microcontroller is powered up.

4.2.3 Debug USB Connectivity

The PIC32MX USB Starter Board includes a PIC18LF4550 USB microcontroller that provides debugger connectivity over USB. The PIC18LF4550 is hard-wired to the PIC32MX device to provide two types of protocol translation:

• I/O pins of PIC18LF4550 to ICSP™ pins of PIC32MX

• I/O pins of PIC18LF4550 to JTAG pins of PIC32MX The PIC32MX USB Starter Board currently uses the JT AG pins of the PIC32MX device

for programming and debugging.

4.2.4 PIC32MX USB Connectivity

There are three possible ways to connect to the PIC32MX USB microcontroller:

• HOST Mode

Connect the device to the Type A connector J4, located on the top side of the USB starter board. If using the Debug USB port to power the Host port, install jumper JP2 to short the back-power prevention diode. Note that a maximum of ~400 mA can be supplied from the Debug USB port to the Host port using this method. If the full 500 mA supply is needed, an external supply must be connected to the application board. Also, remove JP2 to prevent back powering the Debug USB port.

•DEVICE Mode

First, connect the debug Mini-B USB cable to port J1. Next, connect the USB starter board to the host using a cable with a Type-B Micro plug to the USB starter board’s Micro A/B port J5, located on the bottom side of the USB starter board. The other end of the cable must have a Type-A plug. Connect it to a USB host.

• OTG Mode

Connect the USB starter board to the OTG device using an OTG Micro A/B cable to the Micro A/B port J5, located on the bottom side of the USB starter board. The USB starter board provides an on board power supply capable of providing 120mA Max. This supply is controlled by the PIC32MX460 microcontroller.

4.2.5 Switches

Push-butt on switches provide the following functionality:

• SW1: Active-low switch connected to RD6

• SW2: Active-low switch connected to RD7

• SW3: Active-low switch connected to RD13

The switches do not have any debounce circuitry and require the use of internal pull-up resistors; this allows you to investigate software debounce techniques. When Idle, the switches are pulled high (+3.3V). When pressed, they are grounded.

4.2.6 LEDs

The RD0 through RD2 LEDs are connected to PORTD of the processor. The PORTD pins are set high to light the LEDs.

4.2.7 Oscillator Options

The installed microcontroller has an oscillator circuit connected to it. The main oscillator uses an 8 MHz crystal (Y2) and functions as the controller’s primary oscillator. Use of an external crystal is required to develop USB applications. USB specification dictates frequency tolerance of +/- 0.25% for full speed. Non-USB applications can use the internal oscillators. The USB starter board also has provisions for an external secondary oscillator (Y3); however, this is not populated.

The PIC18LF4550 is independently clocked and has its own 8 MHz crystal (Y1).

4.2.8 120-Pin Modular Expansion Connector

The PIC32MX USB Starter Board has been designed with a 120-pin modular expansion interface, which allows the board to provide basic generic functionality now and easy extendability to new technologies as they become available.
