Attention: If this is the first time the user is building/running this version of the demo, the user must complete this step before proceeding further. Otherwise, the user 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.
Any Serial Terminal application, such as Tera Term terminal application.

Because Microchip regularly updates tools, occasionally issue(s) could be discovered while using the newer versions of the tools. If the project does not 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 (DS90003305).

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.

The user could use this demonstration as an example to add WiFi 7 click functionality to the 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.
1. If the user has not downloaded the WiFi 7 click demo yet Click Here to download, otherwise go to next step.
2. Unzip the downloaded .zip file.
3. From the unzipped folder wifi_7/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 WiFi 7 click 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...
