Arduino IDE

Prerequisites

  • Install the Arduino IDE from arduino.cc.
  • Clone or download the RnCAtmelCrypto code to your desktop.
  • Copy all files to the library folder within your Arduino working library.
  • Start the Arduino IDE.
  • Follow the cryptoauth-arduino directory into the Examples directory. Start the file Crypto_Examples.ino from within the Crypto_Examples folder.
  • Follow the CmdMessenger directory into the Examples directory. Start the file example_utf8.ino from within the CmdMessenger folder.
  • Follow the micro-ecc directory into the Examples directory. Start the file micro-ecc.ino from within the micro-ecc folder. The example reproduces the ECDSA of the ASIC based crypto accelerator chip in python.

Beside this, to follow through with all examples it also takes:

For NFC Transponder:

For Public Ledger/Blockchain:

Raspberry Pi

##Building

Install build-essential, autotools-dev, automake, autoconf, libtool, libxml2-dev, check, texinfo, and libgcrypt (libgcrypt11-dev on Debian variants)

Run ./autogen.sh. This will generate the required README file from README.md as well as installing the required BETA version of libcryptoauth-0.2 (sudo is used to install this library)

You can run eclet locally, or install it to the system by running sudo make install

In case this library is used on Raspberry Pi boards I2C functionality has to be activated first.

The I2C bus allows multiple devices to be connected to your Raspberry Pi, each with a unique address, that can often be set by changing jumper settings on the module. It is very useful to be able to see which devices are connected to your Pi as a way of making sure everything is working.

Run the following commands in the Terminal to install the i2c-tools utility.

1. sudo apt-get install -y python-smbus
2. sudo apt-get install -y i2c-tools

Run sudo raspi-config and follow the prompts to install i2c support for the ARM core and linux kernel

Go to Interfacing Options

Raspberry Kernel Interface Options

then I2C

Raspberry Kernel I2C Select

Enable!

Raspberry Kernel I2C Confirm

Raspberry Kernel I2C Confirmed

Then reboot!

We also recommend going through the steps below to manually check everything was added by raspi-config!

Now when you log in you can type the following command to see all the connected devices

1. i2cdetect 1

In case this doesn't work ddd the following line to /boot/config.txt

1. dtparam=i2c_arm=on

Add the following line to /etc/modules

1. i2c-dev
