A small RaspberryPI compatible PCB for the ATECC608A Security Chip.

First you have to enable the I²C interface on the RaspberryPI. On Raspbian you can do this following these steps:

• add or uncomment the line dtparam=i2c_arm=on inside the file /boot/config.txt
• enable the i2c-dev module using raspi-config or by adding the line i2c-dev to /etc/modules
• reboot

If you want to access the I²C interface using a non-root user you also need to add this user to the group i2c by running the command adduser <username> i2c.

On Raspbian you can use python to test whether the chip works:

# apt install build-essential python python-pip cmake libudev-dev libusb-1.0-0-dev libffi-dev libssl-dev git
# git clone https://github.com/MicrochipTech/cryptoauthtools.git
# cd cryptoauthtools/python/examples
# pip install -r requirements.txt
# python info.py -i i2c
