# This setup will install all packages and configure the raspberry-pi
# to run MagicJoy software
#
# THIS SCRIPT MUST BE RUN WITH: sudo setup.sh
#
#
# 1- update /boot/config.txt file to enable SPI (PiCan board) and I2C
#    (joy ADC and display)
#
# 2- update /etc/network/interfaces to add PiCan net interface
#
# 3- update /etc/modules to load PiCan modules at raspberry startup 
#
# 4- apt install all required packages
#
# 5- pip3 install all python packages (ADC, Screen, ...)
