If this is the first time you are building/running this version of the demo, you must complete this step before proceeding further. Otherwise, you may skip this step.

Hardware Used:

Software/Tools Used:

This project has been verified to work with the following versions of software tools:

Refer Project Manifest present in harmony-manifest-success.yml under the project folder firmware/src/config/sam_e51_cnano

  • Refer the Release Notes to know the MPLAB X IDE and MCC Plugin version. Alternatively, Click Here
  • Any Serial Terminal application like Tera Term terminal application.

Because Microchip regularly update tools, occasionally issue(s) could be discovered while using the newer versions of the tools. If the project doesn’t seem to work and version incompatibility is suspected, It is recommended to double-check and use the same versions that the project was tested with. To download original version of MPLAB Harmony v3 packages, refer to document How to Use the MPLAB Harmony v3 Project Manifest Feature

Setup:

  • 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

  • Mount the WiFi 7 click board on mikroBUS connector 1 of Curiosity Nano Base

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 (wifi_7/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:

  • Configure the serial port terminal with 9600 baud rate
  • After power up, when the demo is running, the application prints as shown below

  • Change the SSID and Password of your known WiFi credentials in “wifi_7.h” header file and reprogram the project

  • Device connects to the specified WiFi Access Point

Instructions to add WiFi 7 click functionality to your application:

The MPLAB Harmony v3 supports adding WiFi functionality to your application using WINC driver.

Below are Harmony v3 configuration for the WiFi 7 click

  • Connect the WINC components as shown in the below figure
    • Change Configuration of components as shown in the below figures
      • SERCOM1 Configuration
      • MCC Pin Configurator - SPI pin configuration
      • MCC Pin Configurator - additional pin configurations
      • WINC configuration

Note : Other components’ configurations will be default

  • Connect the console and debug system service necessary for WINC driver as shown in the below figure
    • SERCOM5 Configuration
      - MCC Pin Configurator - UART pin configuration
    • Debug Configuration
    • Enable timer system service and core service as needed by the WINC driver

    • Configure the EIC as shown in the below figure
    • You could use this demonstration as an example to add WiFi 7 click functionality to your MPLAB Harmony v3 based application. Follow the below steps.
      Note: This demo can be extended to connect to web to transfer data, refer the reference section below for more applications
