Software Setup
Note: This tutorial assumes you are using the latest stable version of the Arduino IDE on your desktop. If this is your first time using Arduino, please review our tutorial on installing the Arduino IDE. If you have not previously installed an Arduino library, please check out our installation guide.
Installing Arduino
If you haven't used the Arduino IDE before, head on over to our Installing the Arduino IDE tutorial to get set up:

Getting the Arduino Library
To make Configuration and start using your Cryptographic Co-processor, we have written an Arduino Library. It currently supports only the Artemis board family. This is because some of the commands to the Co-processor require a larger I2C buffer. You have two options to install this library:
- Use the library manager or install in the Arduino IDE
We recommend using the library manager to tool within the Arduino IDE (Sketch > Include Library > Manage Libraries...). In the Library Manager, search for Sparkfun_Cryptographic. For help installing the library, check out our How to Install an Arduino Library tutorial.

How do I install a custom Arduino library? It's easy! This tutorial will go over how to install an Arduino library using the Arduino Library Manager. For libraries not linked with the Arduino IDE, we will also go over manually installing an Arduino library. - Download the Github repository
Users can also manually download and install the library from Github. You can Visit the GitHub repository to download the most recent version of the library, or click the link below:
Setting up the Artemis Board
In case you haven't checked out the hookup guide for the RedBoard Artemis, we suggest reviewing it as the features are very different from your standard Arduino Uno.
Installing Artemis Board Package
This tutorial and Arduino Library support the Artemis Boards. You will need to use the Boards manager to install the necessary packages. You can visit the specific section of the Artemis tutorial here, or read the entire tutorial in the link below:

CH340 Driver Installation for the RedBoard Artemis
Don't forget, if you've never connected an CH340 device to your computer before, you may need to install drivers for the USB-to-serial converter. Check out our section on How to Install CH340 Drivers for help with the installation.
