In this project, a LED (Light Emitting Diode) is turned on by the PIC16F15376 microcontroller using the Xpress development board platform.
Launch the New Project Window using one the following methods:
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.
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.
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.
Choose a Project Name. This will be your project's name that the IDE will create.
Note: The name cannot have any empty spaces!
To follow along with these steps, MPLAB® Xpress should be open and the user should be logged in so that the MPLAB Code Configurator plug-in can be used. The setup is described in the Setup and Installation section of this training module. You should see a screen similar to the one below to move on to step 1:
The MPLAB Xpress Development Board should be connected to an available USB port on the host computer through a USB cable to the micro B connector on the board. Drivers should install successfully the first time the board is connected and may take a minute or so.
Create a new "Stand-Alone" project in MPLAB® Xpress for a PIC16F15376 using the MPLAB Xpress Development Board.
Open the MPLAB® Code Configurator using the blue shield link on the toolbar.
A file will automatically download in your browser similar to the picture shown. Click on that file to open it. This is a java application that will launch the MCC.
The process can take several seconds depending on your internet connection speed. Several windows may appear asking if you want to run the program. When the process is complete you will see a new screen appear, separate from the MPLAB Xpress IDE, that is the MCC control screen. In this screen you can select peripherals for your project, setup the oscillator system and other configuration settings, and input and output selections for your device. When all this is competed you can generate project code including a main.c file. All these generated files will be included in your MPLAB Xpress project.
The first window that opens automatically is the system user interface. The system user interface is where core device operational parameters are setup such as oscillator and configuration bits selection.
In order to turn on an LED, one must write the connected pin as a HIGH OUTPUT. HIGH is a computer logic term for outputting an ON pulse. By setting the pin HIGH OUTPUT, the chip is sending an electrical signal out of the pin. Look for the opened MPLAB Code Configurator Pin Manager:
Because the new Xpress Evaluation board uses the on-board LED for a different purpose, we will attach an LED to the board via two jumper wires and a breadboard, through a 1K Ohm resistor. Connect a wire between the RA0 pin on the evaluation board and the resistor. Then, connect the positive (longer) leg of the LED to the resistor. Next, connect a wire between the negative (shorter) leg of the LED and the GND pin on the evaluation board. You can see this picture below:
While we have physically connected the RA0 pin to the LED, we still need to tell the microcontroller to use the RA0 pin as an output to send power to the LED. Therefore, we need to do two things. In the pin configurator window, click the blue lock under Port A, Column 0, Row GPIO Module – GPIO – Output:
Next, we need to tell the PIC16F15376 to turn this pin ON, as mentioned in step 4. To do this, double click Pin Module under Project Resources and check the Start High option in the** Pin Module** window:
Press the Make and Program icon to generate and download the .hex file for the created project.
Program the MPLAB Xpress evaluation board by dragging the project .hex file from the downloads section of the browser and dropping the file on to the XPRESS drive.
If the LED is connected properly, and the program has been built correctly, the LED should turn on once you have flashed the board. The LED should also stay on until the board loses power.
Problems usually come from plugging the LED in the wrong direction. They can also come from turning one pin to output, and the plugging the LED into another pin. If you have problems, check these issues out. If you are still stuck, feel free to leave a comment below!
