 Step-by-Step

1

Launch the new project wizard

Launch the New Project Wizard using one of the following methods:

• From the Toolbar: Click on the New Project icon , or
• From the Menu: Select File ► New Project, or
• From the Keyboard: Ctrl + Shift + N

The project wizard will walk you through the process and prompt you for all the required information. Your selections may be changed after the project has been created by modifying the project's properties.

2

Choose Project

a

Choose Microchip Embedded from the Categories column (center).

b

Choose Standalone Project from the Projects column (right).

c

Click the Next > button.

Select Device

a

Choose the device family from the Family drop-down box.

​

If you have used MPLAB X IDE previously, choosing Recently Used from the Family drop-down box will filter the Device list to the 3 devices you have used most recently.

b

Choose your device's part number from the Device drop down box. You may also type in the part number directly, and the list will adjust to the characters you enter.

Select Header

​

The wizard will automatically skip this step if a header is not available for your selected device.

If you are using a debug header with your debugger, select it from the Supported Debug Header drop-down box. They are listed by the header's part number.
If you are not using a debug header (i.e. the debugger is directly connected to the target device), select None.

5

Select Tool

If you are using a hardware debugger / programmer, you should see a serial number under its heading if it is connected to your system. Click on the serial number to associate that specific tool with your project. It is important to select the serial number itself because MPLAB X IDE permits multiple projects to be open simultaneously, and each one may use a different debug tool. For example, if you have three ICD3's connected to your PC, you could have three projects open and each one assigned to a different ICD3. This makes it possible to simultaneously debug multiple applications in the same instance of MPLAB X IDE.

For software based tools, such as the simulator, you only need to click on the tool's name to select it.

​

Hover your mouse pointer over the colored dots to see their meaning for a specific tool. Red = No Support, Yellow = Beta Support, Green = Production Tested.

6

Select Plug-in Board

​

The wizard will automatically skip this step if a plug-in board is not available for your selected device.

If you are using a plug-in board to enhance the features of your debugger (usually the Real ICE), select it from the Selected Plugin Board drop-down box. They are listed by function.
If you are not using a plug-in board (i.e. standard debugger configuration), select None.

7

Select Compiler

The IDE will display all compilers available on your system that support your selected device. Select the compiler (including version number) you wish to use for building the project.

8

Select Project Name and Folder

a

Choose a Project Name. This will be your project's name as well as the name of the project directory (with a ".X" appended) that the IDE will create.

b

Choose a Project Location. This is where the IDE will create the project directory.

If a directory with the specified name already exists and has no MPLAB X IDE project files in it, the IDE will use the existing directory for the new project. If the directory does have MPLAB X IDE files in it from another project, the wizard will give an error that must be fixed by choosing a different project name or location. If the directory does not exist, the IDE will create it and use it for the new project.

Launch MCC

Open the MPLAB Code Configurator under the Tools -> Embedded menu of MPLAB X IDE.

System Setup

From Project resources choose System Module to open the System Setup window within MCC.

• In the clock settings, make sure you select INTOSC
• Select the system clock FOSC.
• Set Internal Clock to 4MHz_HF setting.
• The Curiosity Board uses a programmer/debugger on board (PKOB) and uses a Low Voltage Program method to program the MCU, therefore we must enable low voltage programming by checking the Low-voltage programming Enable box.

Timer 2 Setup

Add the TMR2 peripheral to the project from the Device Resources area of MCC. To do that, scroll down to the Timer entry and expand the list by clicking on the arrow. Now double click-on the TMR2 entry to add it to the Project Resources list. Then click on the TMR2 to open the configuration setup screen.

1. Check the Enable Timer box
2. Select Clock Source LFINTOSC,
3. Select Postscaler 1:10
4. Select Prescaler 1:32
5. Set Timer period value to 1 second
6. Set External Reset Source to CLC4OUT
7. Set Control mode setting to Roll over pulse
8. Set Start/Reset Option to Resets at TMR2_ers = 1
9. Leave the Enable Timer Interrupt box unchecked.

Timer 0 Setup

Add the TMR0 peripheral to the project from the Device Resources area of MCC. To do that, scroll down to the Timer entry and expand the list by clicking on the arrow. Now double click-on the TMR0 entry to add it to the Project Resources list. Then click on the TMR0 to open the configuration setup screen.

1. Check the Enable Prescaler box and set to 1:256
2. Select Clock Source: FOSC/4
3. Set Timer Period to: 32.768 ms

CLC1-CLC4 Setup

Add the CLC1 - CLC4 peripherals to the project from the Device Resources area of MCC. To do that, scroll down to the CLC entry and expand the list by clicking on the arrow. Now double click-on the CLC1 through CLC4 one at a time to add them to the Project Resources list. Then click on the CLC to open the configuration setup screen.

CLC1

2. Click on RC5 lock in the CLC2OUT row to turn the lock green
3. Click on RA2 lock in the CLC4OUT row to turn the lock green

Pin Module Setup

Check the RA2 and RA5 Output Box and uncheck the WPU and Analog Boxes

Uncheck the RC4 Output Box, WPU and Analog Boxes
Check the RA5 Output Box and uncheck the WPU and Analog Boxes

Generate Driver Code

Click on the Generate button in the Project Resources area of the MCC screen to have the MCC create the drivers and a base main.c file for the project.

main.c

Since the project runs completely independent of the core, the generated main.c doesn't need any modification. The default while(1) loop will be the only code running.

    while (1)
    {
        // Add your application code
    }

/**
 End of File
*/

Build Project

Click on the Build Project Icon (the Hammer) to compile the code and you will see a BUILD SUCCESSFUL message in the output window of MPLAB X within several seconds of processing time.

BUILD SUCCESSFUL (total time: 7s)

Make sure your Curiosity Board is connected to the USB port. Then click on the Make and Program Device icon. This will build the project again and launch the programmer built into the Curiosity Board. In the output window you should see a series of messages and when successful it will end with a Programming and Verify Successful message.
