Getting Started Application with SAM E54 Curiosity Ultra Development Board

Download


Description

This application demonstrates an 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 SAM E54 Curiosity Ultra Development Board.

The demo application has additional functionality to print the current room temperature periodically using on board temperature sensor.

Modules/Technology Used:

  • Peripheral Modules
    • SERCOM
    • RTC
    • EIC
    • DMAC

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/sam_e54_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

Hardware Setup:

  • Connect the SAM E54 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 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 “ATSAME54P20A”
  • 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 (same54c_getting_started/firmware/sam_e54_cult.X) in MPLAB X IDE
  • Ensure “SAM E54 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

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 LED1 on the SAM E54 Curiosity Ultra Development Board toggles on every timeout basis and the default periodicity of the timeout is 500 milliseconds.
  • And the LED toggling rate is displayed on the serial terminal.
  • Press the switch SW1 on the SAM E54 Curiosity Ultra Development Board to change the periodicity of the timeout to one second.
  • Every subsequent pressing of the switch SW1 on the SAM E54 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.
  • Press the switch SW2 on the SAM E54 Curiosity Ultra 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 SAM E54 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 on every time user press the switch SW1 on the SAM E54 Curiosity Ultra Development Board.
  • Below diagram shows the sample output log displayed on command prompt.
