  • Follow the steps in Running the Demo section below.

Programming/Debugging Application Project

  • Open the project (flash_2/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

  • Reset the device by power cycle.
  • LED0 is turned ON when the data read from SST26 Flash matches with the data written using SAM E51 Curiosity Nano Evaluation Kit.

Instructions to Add Flash 2 Click Functionality to the Application

The user could use this demonstration as an example to add Flash 2 Click functionality to the MPLAB Harmony v3 based application. Follow the below steps.

  1. If the user has not downloaded the Flash 2 Click demo yet Click Here to download, otherwise go to next step.
  2. Unzip the downloaded .zip file.
  3. From the unzipped folder flash_2/firmware/src, copy the folder click_routines to the folder firmware/src under the MPLAB Harmony v3 application project.
  4. Open MPLAB X IDE.
  5. Open the 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...
  7. Click on Add Folder... button.
  8. Select the click_routines folder and select Files of Types as Header Files.
  9. Click on Add button to add the selected folder.
  10. The Flash 2 Click example header files gets added to the project.
  11. In the project explorer, right click on folder Source Files and add a sub folder click_routines by selecting Add Existing Items from Folders...
  12. Click on Add Folder... button.
  13. Select the click_routines folder and select Files of Types as Source Files.
  14. Click on Add button to add the selected folder.
  15. The Flash 2 Click example source files gets added to the project.
  16. The Flash 2 Click example uses the SPI, SST26 Driver, USART peripherals and PORT pins. The configuration of these peripherals for the application depends on the 32-bit MCU and development board the user is using.
    • Configure SPI:
      • Add the SERCOM peripheral block to the MCC project graph.
      • Configure SPI Pins using MCC Pin configuration Window.
        The SPI configuration depends on:
        • 32-bit MCU
        • 32-bit MCU development board
        • The socket on which the user has mounted the Flash 2 Click board

          Example: The Flash 2 Click example on SAM E51 Curiosity Nano Evaluation Kit uses mikroBUS socket #1 on the Curiosity Nano Base for Click boards to mount the Flash 2 Click board. The SPI lines from MCU coming to this socket are from the SERCOM1 peripheral on the MCU.

          Figure 3-92. MCC Project Graph - SPI Configuration
          Figure 3-93. MCC Pin Configurator - SPI Pin Configuration
    • Configure USART:
      • Add the SERCOM peripheral block to the MCC project graph.
      • Configure USART Pins using MCC Pin configuration Window.
        The USART configuration depends on:
        • 32-bit MCU
        • 32-bit MCU development board
        • The socket on which the user has mounted the Flash 2 Click board

          Example: The Flash 2 Click example on SAM E51 Curiosity Nano Evaluation Kit uses mikroBUS socket #1 on the Curiosity Nano Base for Click boards to mount the Flash 2 Click board. The USART lines from MCU coming to this socket are from the SERCOM1 peripheral on the MCU.

          Figure 3-94. MCC Project Graph - USART Configuration
          Figure 3-95. MCC Pin Configurator - USART Pin Configuration
    • Configure SST26 Driver:
      • Add the SST26 Driver peripheral block to the MCC project graph.
      • Connect SERCOM 1 to SST26 Driver block.
        Figure 3-96. MCC Project Graph - SST26 Configuration
    • Configure BSP:
      • Add the SAM E51 Curiosity Nano BSP (Board Support packages).
    • Configure Core:
      • Add the Core block to the MCC project graph.
        Figure 3-97. MCC Project Graph - Core Configuration

    The click_routines folder contain an example C source file flash_2_example.c. The user could use flash_2_example.c as a reference to add Flash 2 Click functionality to the application.
