3.8.1 Getting Started Application on PIC32CM MC00 Curiosity Pro Development Board

Download

Description

The application reads current room temperature from the temperature sensor and light level from light sensor on the I/O1 Xplained Pro Extension and sends it to the console.

The application will utilize below peripherals:

  • SERCOM0 (as I²C) PLIB to read the temperature from a temperature sensor.
  • SERCOM2 (as Universal Synchronous Asynchronous Receiver Transmitter (USART)) PLIBs and STDIO library to print the temperature values on a COM (serial) port terminal application running on a PC.
  • The ADC peripheral library is used to read data from the light sensor.

Modules/Technology Used

  • Peripheral Modules
    • SERCOM2(I2C)
    • ADC
    • SERCOM0(USART)

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/pic32cm_mc00_curiosity_pro.

  • Refer the Release Notes to know the MPLAB X IDE and MCC Plugin version.
  • Any Serial Terminal application like 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 PIC32CM MC00 Curiosity Pro Development Board 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 PPIC32CM1216MC00048.
      • 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 (pic32cm_mc_curiosity_getting_started/firmware/pic32cm_mc00_curiosity_pro.X) in MPLAB X IDE.
  • Ensure PIC32CM MC00 Curiosity Pro 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 the PC (from the Windows® Start menu by pressing the Start button).
  • Set the baud rate to 9600.
  • Press the Reset switch on the PIC32CM MC00 Curiosity Pro Development Board.
  • The application prints temperature and light sensor continuously.
  • Cover the light sensor on the I/O Xplained Pro board by placing the hand over it (or another element to put the light sensor in a dark environment) to vary the light value. Place the finger on the temperature sensor to vary the temperature.
