The Arduino Integrated Development Environment – or Arduino Software (IDE) – contains a text editor for writing code, a message area, a text console, a toolbar with buttons for standard functions, and a series of menus. It connects to different boards to upload programs and communicate with them.

You need to download and install Arduino IDE; you can find it here.

After installing Arduino IDE, open it, and you will see the following window:

Arduino IDE Main View

The next step to use our boards is to install the board’s core in the Arduino IDE. Here is a quick guide on how to install them:

Installing the Arduino SAMD core:

You must install the latest Arduino SAMD core.

1. In the menu bar, select Tools > Boards > Board Manager.

Board Manager Menu

2. A side window will open and in the search bar, write SAMD, a list of cores will appear, click on the install button for Arduino SAMD Boards (32-bits ARM Cortex-Mo+).

Board Manager

3. Installing the Electronic Cats SAMD Arduino Core: https://electroniccats.github.io/Arduino_Boards_Index/package_electroniccats_index.json

Arduino allows us to add custom cores or support for non-Arduino boards using the board manager. To do this we need to add a URL on the board manager configuration. Go to File > Preferences > Additional boards manager URLs.

Preferences Menu

Preferences

• If you already have a URL in the space there, you can click the button to the left, jump to another line and paste the Electronic Cats URL there. https://electroniccats.github.io/Arduino_Boards_Index/package_electroniccats_index.json

Additional Boards Manager URLs Window

• Press the "OK" button.
• Open the "Boards Manager" that is in Tools > Board > Board Manager.
• Now write Electronic Cats in the search bar.
• Click on install, wait for the installation to finish, and close the window.

4. In Tools > Boards, scroll down in the board list until you see the Electronic Cats SAMD boards.

ElectronicCats Boards Installed

After downloading the core, you can upload the .ino files from the repository like you would do for any other board using the Arduino IDE.

Board Selection

Using the Python tool is the easiest and most recommended way to flash firmware to the CC1352, since it works on any operating system. But before we start, there are some preparations we need to do in order to use the python tool.

1. Download the python tool from our repository or clone the whole repository (recommended) to your computer.

2. Upload the SerialPassThroughWithBoot firmware to your board's main chip.

3. Download Python using the following link. Look for the Operating System of your preference, in this case we use Windows.

Python Download Page

4. After the download is complete, install the software.
5. We recommend that you select the ‘Add to PATH’ option when installing it so you do not have to do it manually later.

Python Installer

6. Some python plugins are required, we can install them using the command line.

• On the search bar, type CMD, and run it as administrator.

Command Prompt as Administrator

• Execute the following commands to install the plugins:

  • pip install pyserial

  • pip install intelhex

  • pip install python-magic

Install Requirements

7. When the installation is finished, open a new cmd window or clean the console with the cls command. Then go to the path where you saved the python tool (cc2538-bsl.py) found on our repository using the cd command: cd <directory_route>

8. Open the folder where you saved the python tool and copy the desired firmware (the one you are going to load to the board) onto the same folder where you have the python tool.

9. Now run the command: python cc2538-bsl.py -h.

10. The following menu will come up:

Help Command

11. To continue with the process you need to know which COM port number has been assigned to your CatSniffer. Go to Device Manager and look for your CatSniffer device. For this example COM90 is what we are looking for.

Device Manager

12. Return to the cmd console and run the command python cc2538-bsl.py -p COMXX. The argument -p is used to open the port, if the port is opened, then the connection was successful.

Check COM Port

13. Put your CatSniffer in bootloader mode and then write in console:

python cc2538-bsl.py -e -w -v -p COM58 .\sniffer_fw.hex 

The argument -e erase the memory, the -w write on the chip and -v verify the image, the last parameter is the name of the file with extension. The .hex file must be on the folder cc2538-bsl.

Check COM Port

Load Firmware

14. LED 4 will start blinking once the procedure finishes, indicating that CatSniffer has been successfully flashed.
