Getting Started Application on PIC32CM JH01 Curiosity Pro Development Board

Download

Description:

This application demonstrates an LED (LED0) toggle on timeout basis and print the LED toggling rate on the serial terminal. The periodicity of the timeout will change from 500 milliseconds to one second, two seconds, four seconds and back to 500 milliseconds every time you press the switch SW0 on the PIC32CM JH01 Curiosity Pro Development Board.

The demo application has extended functionality to read and print the current room temperature periodically when the extension header (EXT1) is plugged with the I/O1 Xplained Pro Extension Kit. The temperature reading is displayed on a serial console periodically

Modules/Technology Used:

Peripheral Modules
- EIC
- RTC
- GPIO
- DMAC
- SERCOM (USART)
- SERCOM(I2C)

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_jh01_cpro

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

Hardware Setup 1:

Connect the PIC32CM JH01 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

Hardware Setup 2:

Connect the PIC32CM JH01 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
To test the extended functionality, connect the I/O1 Xplained Pro Extension Kit to the extension header EXT1 (J200) on the PIC32CM JH01 Curiosity Pro Development Board.

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 “PIC32CM5164JH01100”
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_jh01_cpro_getting_started/firmware/pic32cm_jh01_cpro.X) in MPLAB X IDE
Ensure “PIC32CM JH01 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/PuTTY terminal application on your PC (from the Windows® Start menu by pressing the Start button)
Set the baud rate to 115200
An LED (LED0) on the PIC32CM JH01 Curiosity Pro Development Board toggles on every timeout basis and the default periodicity of the timeout is 500 milliseconds
And also, the LED toggling rate is displayed on the serial terminal
Press the switch SW0 on the PIC32CM JH01 Curiosity Pro Development Board to change the default periodicity of the timeout to one second
Every subsequent pressing of the switch SW0 on the PIC32CM JH01 Curiosity Pro Development Board changes the periodicity of the timeout to 2 seconds, 4 seconds, 500 milliseconds, and back to 1 second in cyclic order
See the following figure for the output.
To Test the Extended functionality using I/O1 Xplained Pro Extension Kit:
- Perform Hardware Setup 2 steps mentioned above, if not done already.
- Reset or power cycle the device. LED0 toggles for every 500 milliseconds during power cycle and the LED toggling rate is displayed on the serial terminal.
- Press any key on your Computer’s keyboard to read and print the Temperature from the I/O1 Xplained Pro Extension Kit).
- The temperature read is displayed on a serial console on a periodical basis.
- The periodicity of reading temperature will be changed between 500 milliseconds, one second, two seconds, four seconds, and back to 500 milliseconds every time the user presses the switch SW0 on the PIC32CM JH01 Curiosity Pro Development Board.
- Press any key on the keyboard to start printing the LED Toggling rate
- The subsequent key press from the keyboard switches between printing the LED Toggling rate or temperature values on the serial terminal.
- See the following figure for the output.

Reference Training Module: Getting Started with Harmony v3 Peripheral Libraries on SAMC2x MCUs
This application demo builds and works out of box by following the instructions above in “Running the Demo” section. If you need to enhance/customize this application demo, you need to use the MPLAB Harmony v3 Software framework. Refer links below to setup and build your applications using MPLAB Harmony.
- How to Setup MPLAB Harmony v3 Software Development Framework
- How to Build an Application by Adding a New PLIB, Driver, or Middleware to an Existing MPLAB Harmony v3 Project
- MPLAB Harmony v3 is also configurable through MPLAB Code Configurator (MCC). Refer to the below links for specific instructions to use MPLAB Harmony v3 with MCC.
