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\evsys_trigger\src\config\pic32cm_ls00_cnano.

  • Refer the Release Notes to know the MPLAB X IDE and MCC Plugin version.

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 PIC32CM LS00 Curiosity Nano+ Touch 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,
    1. Create Prebuilt Project,
      • Click the Browse button to select the prebuilt hex file.
      • Select Device as PIC32CM5164LS00048.
      • Ensure the proper tool is selected under Hardware Tool and click on Next button.
    2. Select Project Name and Folder,
      • Select appropriate project name and folder and click on Finish button
  • In MPLAB X IDE, click on Make and Program Device button to program the device.
  • Follow the steps in Running the Demo section below.

Programming/Debugging Application Project

  • Open the project (evsys_trigger\firmware\evsys_trigger\evsys_pic32cm_ls00_cnanogroup) in MPLAB X IDE.
  • Ensure PIC32CM LS00 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.

Toggling LED Output
