Note the following details of the code protection feature on Microchip devices:

•

Microchip products meet the specification contained in their particular Microchip Data Sheet.

•

Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

intended manner and under normal conditions.

•

There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

•

Microchip is willing to work with the customer who is concerned about the integrity of their code.

Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not

mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

PERIPHERAL LIBRARIES

PIC32 MCUs integrate a large number of on-chip high-performance peripherals.

To accelerate the usage of these peripherals, the MPLAB C32 compiler for PIC32

includes software peripheral libraries compatible with the 16-bit Microchip MCUs. The

peripheral libraries are distributed in source and object format along with a detailed API

description document. Software applications using MPLAB C32 compiler may call

peripheral library functions by simply including the appropriate header file in their

source files – the MPLAB C32 compiler has built-in knowledge of library header and

archive files.

The peripheral include files are located in C:\Program Files\Microchip\MPLAB

C32\pic32mx\include\peripheraland the full source code is located in

C:\Program Files\Microchip\MPLAB C32\pic32-libs\peripheralloca-

5.4

STEP-BY-STEP GUIDE OVERVIEW

To create code that is executable by the PIC32 MCU, source files need to be part of a

project. The code can then be built into executable code using selected language tools

(assemblers, compilers, linkers, etc.). In MPLAB IDE, the project manager controls this

process and will guide us through most of these steps.

All projects will have these basic steps:

- Select Device

The capabilities of MPLAB IDE vary according to which device is selected. Device

selection should be completed before starting a project.

- Create Project

MPLAB IDE Project Wizard will be used to create a project.

- Select Language Tools

In the Project Wizard the language tools will be selected. For this tutorial, the PIC32

tools will be used. For other projects, either other Microchip or third party tools might

be selected.

- Add Files in Project

We’ll add a template file and a linker script to the project.

- Create Code

DS61146B-page 22

Step-by-Step Procedures to Setup, Build, and Run a Demo Project

Some very simple code will be added to the template file to print a “Hello World…”

string to a serial console connected to the evaluation board. We will use the UART

Peripheral Library provided by Microchip.

- Build Project

The project will be built – causing the source files to be compiled and linked into

machine code that can run on the selected PIC32 MCU.

- Test Code

Finally, the code will be tested by running it on the evaluation board.

Note: Some aspects of the user interface will change in future product releases

and the screen shots in this guide may not exactly match the appearance

of the MPLAB IDE desktop in later releases.

5.5

SELECTING THE DEVICE

Choose Configure>Select Device from the top IDE menu. In the Device dialog, select

the PIC32 variant from the drop-down list.

FIGURE 5-2:

MPLAB IDE SELECT DEVICE

The “lights” indicate which MPLAB IDE components support this device.

- A green light indicates full support.

- A yellow light indicates preliminary support for an upcoming part by the

particular MPLAB IDE tool component. Components with a yellow light

instead of a green light are often intended for early adopters of new parts

who need quick support and understand that some operations or functions

may not be available.

- A red light indicates no support for this device. Support may be forthcoming or

inappropriate for the tool.

DS61146B-page 23

5.6

CREATING THE PROJECT

The next step is to create a project using the Project Wizard. A project is the way the

files are organized to be compiled, assembled and linked. We will use a single “C” file

for this project and a linker script.

Choose Project>Project Wizard.

From the Welcome dialog, click on Next> to advance.

The Step One dialog allows you to select the device, which we’ve already done. Make

sure that it displays the proper PIC32 variant. If not, select the required PIC32 variant

from the drop down menu. Click Next>.

5.7

SETTING UP LANGUAGE TOOLS

Step Two of the Project Wizard sets up the language tools that are used with this

project. Make sure the “Show all installed toolsuites” checkbox is checked. Select

Microchip PIC32 C Compiler Toolsuite in the Active Toolsuite list box.

Then “MPLAB PIC32 Assembler (PIC32-as.exe)”, “MPLAB PIC32 C Compiler

(PIC32-gcc.exe)”, “MPLAB PIC32 Object Linker (PIC32-ld.exe)”, and “MPLAB PIC32

Archiver (PIC32-ar.exe)”, should be visible in the Toolsuite Contents box. Click on each

one to see its location. If MPLAB IDE was installed into the default directory, the paths

for these files will be:

• for the MPLAB PIC32 assembler:

-C:\Program Files\Microchip\MPLAB IDE\ MPLAB

C32\bin\PIC32-as.exe

• for the MPLAB PIC32 compiler:

-C:\Program Files\Microchip\MPLAB IDE\ MPLAB C32\bin\

PIC32-gcc.exe

• for the MPLAB PIC32 Object Linker:

-C:\Program Files\Microchip\MPLAB IDE\ MPLAB

C32\bin\PIC32-ld.exe

• for the MPLAB PIC32 Archiver:

-C:\Program Files\Microchip\MPLAB IDE\ MPLAB

C32\bin\PIC32-ar.exe

If these paths do not show up correctly, use the Browse button to set them to the proper

files in the MPLAB IDE subfolders.

When you are finished, click Next>.

5.9

ADDING FILES TO THE PROJECT

Step Four of the Project Wizard allows file selection for the project. This is where we

can add existing files to our project. In the current example we don’t have a previously

created file but we’ll create one once we’re done with the new project setting.

Just press Next> and the following Summary Screen will show up:

FIGURE 5-6:

Getting Started with PIC32

Be sure to save the workspace in the Projects32 directory and name this workspace

using the same name as for the project: MyTestProject.

Click Save.

The project space is now completely created and it should look like that:

FIGURE 5-8:

MPLAB IDE PROJECT SAVE

Now we’ll create our C source file. If the MPLAB IDE Editor window is not open, click

File->New from the top menu or the New File menu shortcut on the standard toolbar.

The Editor window will show up.

Let’s type in a very simple Hello World program in the Editor window and save it in

Projects32 directory as main.c. We’ll use the UART Peripheral Library provided by

Microchip:

FIGURE 5-9:

MPLAB IDE MAIN.C FILE

To add the newly created main.cfile to our project just right click on the Source Files

folder in the MPLAB IDE MyTestProject.mcp window and select Add File. Browse and

select main.cfile from the Projects32 directory.

Note: If the Project window is not open, select View->Project from the top IDE

menu.

The linker script that’s needed for this project is selected automatically by the MPLAB

IDE. We don’t need to add any other file to our project.

DS61146B-page 29

Step-by-Step Procedures to Setup, Build, and Run a Demo Project

5.10 ATTACHING THE DEBUGGER

In order to test the code using the PIC32 Starter Kit, please refer to the PIC32MX

Starter Kit User’s Guide (DS61144 ) for a sample project and a step-by-step getting

started info.

For the purpose of testing our code in this document we will use an Explorer 16

Development board (DM240001), a MPLAB REAL ICE In-Circuit Debugger

(DV244005) and a PIC32MX360F512L PIM (MA320001) together with a 9V universal

power supply, a serial cable and a USB cable for connecting the REAL ICE to the

development board.

FIGURE 5-11:

EXPLORER 16, MPLAB^®REAL ICE™ AND

PIC32MX360F512L PIM

Take the following steps to ensure proper connection of the REAL ICE to the Explorer

16 development board:

1. Connect the MPLAB REAL ICE module to the PC with the USB cable.

2. Connect the MPLAB REAL ICE to the Explorer 16 Development Board with the

short RJ-11 cable.

3. Apply power to the Explorer 16 board.

4. From the Debugger menu, click Select Tool > MPLAB REAL ICE to set the

MPLAB REAL ICE as the debug tool in MPLAB IDE.

5. From the Debugger menu, select Connect to connect the debugger to the device.

MPLAB IDE should report in the Output window that it found the

PIC32MX360F512L device.

Note: MPLAB IDE may need to download new firmware if this is the first time the

MPLAB REAL ICE is being used with a PIC32 device. Allow it to do so.

Once you have performed these steps, go to the MPLAB IDE window and from the

Debugger->Select Tool menu select the debugging tool you’re using to connect to the

board (i.e., MPLAB REAL ICE should be within the available choices).

Once you have selected the tool, the “Debug Toolbar” should be present just below the

main menu bar, together with other toolbars that may be selected.

Note: Be sure to select Debug from the MPLAB IDE Build Configuration drop

down list.

DS61146B-page 31

Getting Started with PIC32

5.11 BUILDING THE PROJECT

From the Project menu, we can compile and link the current files.

To build the project, select either:

- Project>Build All

- Right click on the project name in the project window and select Build All

- Click the Build All icon on the Project toolbar. Hover the mouse over icons to

see pop-up text of what they represent.

The Output window shows the result of the build process. There should be no errors

on any step.

FIGURE 5-12:

MPLAB IDE PROJECT BUILD

5.12 TESTING THE CODE

First download the hex image of the program we just built by selecting Debugger->Pro-

gram from the Debugger menu or directly program from the “Debug Toolbar”. The

programming operation should occur with no errors.

In order to test our example application, we need to set-up the PC part too.

Connect a serial cable between the board RS-232 connector and one of the PC’s COM

ports and open a Hyper Terminal application on the PC (Programs->Accesso-

ries->Communications->Hyper Terminal).

Select a proper name for this connection, click OK and then, in the “Connect To” screen

select the COM port that’s connected to the development board.

DS61146B-page 32

Step-by-Step Procedures to Setup, Build, and Run a Demo Project

FIGURE 5-13:

HYPER TERMINAL CONNECTION SCREEN

Click OK and, on the next screen, select the following communication settings:

• Bits Per Second: 57600

• Data Bits: 8

• Parity: None

• Stop Bits: 1

• Flow Control: None

Click OK and the Hyper Terminal session should be connected to the serial port on the

development board.

Now return to the MPLAB IDE and double click on the line:

return nc;

in the MPLAB IDE Editor window, the main.cprogram, to set a breakpoint on that line,

just after the call to strlen().

Click Debugger->Run from the main menu, or Run from the Debug toolbar. The

program should start running and it will reach the set breakpoint. The MPLAB IDE

window will look very similar to this one:

3. The menus available under the Debugger top menu

4. The Debug toolbar

5. The Source window, with the breakpoint reached

6. The Disassembly window

7. The Output window

8. The Program Memory window

Now, if you take a look to the PC Hyper Terminal window, you should see the output

sent by our simple test program to the serial line:

FIGURE 5-15:

HYPER TERMINAL RECEIVED CHARACTERS

DS61146B-page 34

Step-by-Step Procedures to Setup, Build, and Run a Demo Project

Also, if you look at the Explorer 16 board, you should see the LED D9 lit on.

This shows that the PIC32 Explorer16 demo board and the MPLAB IDE operate

correctly.

We just made our first “Hello World” program for PIC32.

There are many other things that you can do in the MPLAB IDE to debug your program.

For example, you can notice in that by hovering the mouse over the variable “nc” we

can see its actual value (which should be the number of characters sent to the serial

port by the putsUART2()function).

Other MPLAB IDE debug features:

• Watch window: you can add variables of peripheral SFRs to the watch window

and monitor their values

• Complex Breakpoint manipulation

• All the useful debug commands: step into, step over, etc, using both the C Source

window and the disassembly listing window.

• Profile your code execution and calculate delay times between different points in

your program.

We presented here the essential steps for getting started with PIC32 using the MPLAB

IDE. You are now ready to continue exploring the capabilities of PIC32 and MPLAB

IDE. For further information about PIC32 please see the documentation list provided in

this document. For more information about the MPLAB IDE please see the “MPLAB

IDE Quick Start Guide” (DS51281) available on our site at www.microchip.com
