Getting Started Application on PIC32CK GC01 Curiosity Ultra Development Board

Download

Description

This application demonstrates an LED toggle (LED0 toggles when the switch SW0 is pressed) on a 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 PIC32CK GC01 Curiosity Ultra Development Board.

The demo application has an 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:

System Services
- STDIO

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/pic32ck_gc01_cult
- Refer the Release Notes to know the MPLAB X IDE and MCC Plugin version. Alternatively, Click Here.
- 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. To download original version of MPLAB Harmony v3 packages, refer to document How to Use the MPLAB Harmony v3 Project Manifest Feature

Setup 1:

Connect the Type-A male to Micro-B USB cable to Micro-B DEBUG USB port (J900) to program and debug the PIC32CK GC Curiosity Ultra Development Board.

Setup 2:

Connect the PIC32CK GC01 Curiosity Ultra Development Board to the Host PC as a USB Device through a Type-A male to micro-B USB cable connected to Micro-B Debug USB (J900) port.
To test the extended functionality, connect the I/O1 Xplained Pro Extension Kit (Temperature Sensor) to J500 (Extension Header 1 (EXT1)) on the PIC32CK GC01 Curiosity Ultra 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 “PIC32CK2051GC01144”
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 (pic32ck_gc01_cult_getting_started_started_pic32ck_gc01_cult.X) in MPLAB X IDE
Ensure “PIC32CK GC01 Curiosity Ultra” is selected as hardware tool to program/debug the application
Build the code and program the device by clicking on the “Make and Program Device” button in MPLAB X IDE tool bar
Follow the steps in “Running the Demo” section below

Note: This application is programmed using the PKOB4 tool pack v1.14.1168. If the user sees issues with programming, please install this tool pack version and use it accordingly.

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 LED0 on the PIC32CK GC01 Curiosity Ultra 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 PIC32CK GC01 Curiosity Ultra Development Board to change the periodicity of the timeout to one second.
Every subsequent pressing of the switch SW0 on the PIC32CK GC01 Curiosity Ultra 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 SW1 on the PIC32CK GC01 Curiosity Ultra 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 SW0 (toggles LED0) on the PIC32CK GC01 Curiosity Ultra 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 every time the user presses the switch SW0 on the PIC32CK GC01 Curiosity Ultra Development Board.
Below diagram shows the sample output log displayed on command prompt.
