• Connect the SAM E51 Curiosity Nano Evaluation Kit to the Host PC as a USB Device through a Type-A male to micro-B USB cable connected to Micro-B USB (Debug USB) port

  

Programming hex file:

The pre-built hex file can be programmed by following the below steps.

Steps to program the hex file

• Open MPLAB X IDE
• Close all existing projects in IDE, if any project is opened.
• Go to File -> Import -> Hex/ELF File
• In the “Import Image File” window, Step 1 - Create Prebuilt Project, Click the “Browse” button to select the prebuilt hex file.
• Select Device has “ATSAME51J20A”
• Ensure the proper tool is selected under “Hardware Tool”
• 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 (13dof/firmware/sam_e51_cnano.X) in MPLAB X IDE
• Ensure “SAM E51 Curiosity 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 print the weather (Temperature, Pressure, Gas Resistance and Humidity), motion parameters (Gyroscope, Accelerometer) and geomagnetic data.

  

• For every switch press, the SAM E51 Curiosity Nano Evaluation Kit prints the latest weather, motion and geomagnetic data parameters.

Instructions to add 13dof functionality to your application:

You could use this demonstration as an example to add 13dof functionality to your MPLAB Harmony v3 based application. Follow the below steps.

1. If you haven’t downloaded the 13dof demo yet Click Here to download, otherwise go to next step
2. Unzip the downloaded .zip file
3. From the unzipped folder 13dof/firmware/src, copy the folder click_routines to the folder firmware/src under your MPLAB Harmony v3 application project
4. Open MPLAB X IDE
5. Open your application project
6. 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 13dof click example header files gets added to your project
  

1. 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 13dof click example source files gets added to your project
  

1. The 13dof 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 13dof click board
       Example: The 13dof click example on SAM E51 Curiosity Nano Evaluation Kit uses mikroBUS socket #1 on the Curiosity Nano Base for Click boards to mount the 13dof click board. The I2C lines from MCU coming to this socket are from the SERCOM2 peripheral on the MCU.

     MCC Pin Configurator - I2C pin configuration
     

   • Configure Timer:
     • Configure Timer peripheral block in the MCC project graph
       The Timer configuration depends on - 32-bit MCU
       Example: The 13dof click example on SAM E51 Curiosity Nano Evaluation Kit uses SysTick timer module on the MCU to implement the time requirement of 13dof click routines.
       MCC Project Graph - SysTick configuration
       
   • 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 13dof click routines for the example on SAM E51 Curiosity Nano Evaluation Kit uses the following Harmony PLIB APIs

2. The click_routines folder contain an example C source file 13dof_example.c. You could use 13dof_example.c as a reference to add 13dof functionality to your application.
