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:

MPLAB Harmony v3 “csp” repo v3.8.3
MPLAB Harmony v3 “dev_packs” repo v3.8.0
MPLAB Harmony v3 “mhc” repo v3.6.5
MPLAB Harmony 3 Launcher Plugin v3.6.2
MPLAB X IDE v5.45
MPLAB XC32 Compiler v2.41
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.

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, Step 1 - Create Prebuilt Project, Click the “Browse” button to select the prebuilt hex file.
Select Device has “PIC32CM1216MC00048”
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 (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 your 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 your 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.
