3.6.1 Getting Started Application on SAM E51 Curiosity Nano Evaluation Kit
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 the user presses the switch SW0 on the SAM E51 Curiosity Nano Evaluation Kit.

- SERCOM(USART)
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_e51_cnano.
- Refer the Release Notes to know the MPLAB X IDE and MCC Plugin version.
- Any Serial Terminal application, such as Tera Term terminal application.
Because Microchip regularly updates tools, occasionally issue(s) could be discovered while using the newer versions of the tools. If the project does not 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 (DS90003305).
Setup
- Connect the SAM E51 Curiosity Nano
Evaluation Kit 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.
- 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,
- Create Prebuilt Project,
- Click the Browse button to select the prebuilt hex file.
- Select Device as ATSAME51J20A.
- Ensure the proper tool is selected under Hardware Tool and click on Next button.
- Select Project Name and Folder,
- Select appropriate project name and folder and click on Finish button
- Create Prebuilt Project,
- In MPLAB X IDE, click on Make and Program Device button to program the device.
- Follow the steps in Running the Demo section below.
Programming/Debugging Application Project
- Open the project (same51n_getting_started\firmware\sam_e51_cnano.X) in MPLAB X IDE
- Ensure PKOB nano 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 the PC (from the Windows Start menu by pressing the Start button).
- Set the baud rate to 115200.
- An LED (LED0) on the SAM E51 Curiosity Nano Evaluation Kit 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 SW0 on the SAM E51 Curiosity Nano Evaluation Kit to change the default periodicity of the timeout to one second.
- Every subsequent pressing of the switch SW0 on the SAM E51 Curiosity Nano Evaluation Kit changes the periodicity of the timeout to 2 seconds, 4 seconds, 500 milliseconds, and back to 1 second in cyclic order.
