- Click on Next button
- In the “Import Image File” window, Step 2 - Select Project Name and Folder, select appropriate project name and folder
- Click on Finish button
- In MPLAB X IDE, click on “Make and Program Device” Button. The device gets programmed in sometime
- Follow the steps in “Running the Demo” section below
Programming/Debugging Application Project:
- Open the project (leddriver3/firmware/sam_e51_cnano.X) in MPLAB X IDE
- Ensure “PKOB nano” is selected as hardware tool to program/debug the application
- Build the code and program the device by clicking on the “make and program” button in MPLAB X IDE tool bar
- Follow the steps in “Running the Demo” section below
Running the Demo:
- Open the Tera Term terminal application on your PC (from the Windows® Start menu by pressing the Start button)
- Set the baud rate to 115200
- Press the switch SW0 on the SAM E51 Curiosity Nano Evaluation Kit to display the RGB color (Red/Green/Blue) one by one with 500ms delay on LED Driver 3 click board
- For every switch press, the SAM E51 Curiosity Nano Evaluation Kit displays RGB.
Instructions to add led driver3 functionality to your application:
You could use this demonstration as an example to add led driver3 functionality to your MPLAB Harmony v3 based application. Follow the below steps.
- If you haven’t downloaded the led driver3 demo yet Click Here to download, otherwise go to next step
- Unzip the downloaded .zip file
- From the unzipped folder leddriver3/firmware/src, copy the folder click_routines to the folder firmware/src under your MPLAB Harmony v3 application project
- Open MPLAB X IDE
- Open your application project
- In the project explorer, Right click on folder Header Files
and add a sub folder click_routines by selecting “Add Existing Items from Folders…”
-
Click on “Add Folder…” button
-
Select the “click_routines” folder and select “Files of Types” as Header Files
-
Click on “Add” button to add the selected folder
-
The led driver3 click example header files gets added to your project
- In the project explorer, Right click on folder Source Files
and add a sub folder click_routines by selecting “Add Existing Items from Folders…”
-
Click on “Add Folder…” button
-
Select the “click_routines” folder and select “Files of Types” as Source Files
-
Click on “Add” button to add the selected folder
-
The led driver3 click example source files gets added to your project
-
The led driver3 click example uses the I2C and Timer peripherals. The configuration of these peripherals for your application depends on the 32-bit MCU and development board you are using.
- Configure I2C: - Add the I2C peripheral block to the MCC project graph
- Configure I2C Pins using MCC Pin configuration Window
The I2C configuration depends on - 32-bit MCU - 32-bit MCU development board - The socket on which you have mounted the led driver3 click board
Example: The led driver3 click example on SAM E51 Curiosity Nano Evaluation Kit uses mikroBUS socket #1 on the Curiosity Nano Base for Click boards to mount the led driver3 click board. The I2C lines from MCU coming to this socket are from the SERCOM2 peripheral on the MCU.
MCC Project Graph - I2C configuration
MCC Pin Configurator - I2C pin configuration
- Configure I2C Pins using MCC Pin configuration Window
- Configure Timer:
- Configure Timer peripheral block in the MCC project graph
The Timer configuration depends on - 32-bit MCU
Example: The led driver3 click example on SAM E51 Curiosity Nano Evaluation Kit uses SysTick timer module on the MCU to implement the time requirement of led driver3 click routines.
MCC Project Graph - SysTick configuration
- Configure Timer peripheral block in the MCC project graph
- Map Generic Macros:
- After generating the project, following the above configuration, map the generic macros used in the click routines to the Harmony PLIB APIs of the 32-bit MCU your project is running on
-
The generic macros should be mapped in the header file click_interface.h
Example: The led driver3 click routines for the example on SAM E51 Curiosity Nano Evaluation Kit uses the following Harmony PLIB APIs
- Configure I2C: - Add the I2C peripheral block to the MCC project graph
-
The click_routines folder contain an example C source file leddriver3_example.c. You could use leddriver3_example.c as a reference to add led driver3 functionality to your application.
Comments:
- Reference Training Module:
- This application demo builds and works out of box by following the instructions above in “Running the Demo” section. If you need to enhance/customize this application demo, you need to use the MPLAB Harmony v3 Software framework. Refer links below to setup and build your applications using MPLAB Harmony.
- How to Setup MPLAB Harmony v3 Software Development Framework
