Getting Started Extended Application on Curiosity PIC32MZ EF 2.0 Development Board

Download

Description

This application demonstrates an LED (LED1) 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 SW1 on the Curiosity PIC32MZ EF 2.0 Development Board.

The demo application has extended functionality to print the current room temperature periodically when the XPRO connector is plugged with I/O1 Xplained Pro Extension Kit.

Modules/Technology Used:

  • Peripheral Modules
    • I2C
    • Timer
    • GPIO
    • UART
    • DMA

Hardware Used:

Software/Tools Used:

This project has been verified to work with the following versions of software tools:

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 1:

  • Connect the Curiosity PIC32MZ EF 2.0 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

Setup 2:

  • Connect the Curiosity PIC32MZ EF 2.0 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 (Temperature Sensor) to J501 (Extension Header 1 (EXT1)) on the Curiosity PIC32MZ EF 2.0 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 “PIC32MZ2048EFM144”
  • 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 (getting_started_ext\firmware\pic32mz_ef_curiosity_v2.X) in MPLAB X IDE
  • Ensure “Curiosity/Starter Kits PKOB4” 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 115200
  • Reset or power cycle the device
  • An LED (LED1) on the Curiosity PIC32MZ EF 2.0 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 SW1 on the Curiosity PIC32MZ EF 2.0 Development Board to change the periodicity of the timeout to one second
  • Every subsequent pressing of the switch SW1 on the Curiosity PIC32MZ EF 2.0 Development Board changes the periodicity of the timeout to 2 seconds, 4 seconds, 500 milliseconds, and back to 1 second in cyclic order
  • Testing Extended functionality:
    • Press the switch SW2 on the Curiosity PIC32MZ EF 2.0 Development Board to read and print the Temperature from the Temperature Sensor.
    • The temperature read is displayed on a serial console on a periodical basis
    • Press the switch SW1 on the Curiosity PIC32MZ EF 2.0 Development Board to change the periodicity of the temperature values displayed on the serial console. The periodicity will be changed between 500 milliseconds, one second, two seconds, four seconds and back to 500 milliseconds on every time user press the switch SW1 on the Curiosity PIC32MZ EF 2.0 Development Board.
