Hello World example

This is a general Hello World example to get a standard program on a linux machine like Raspberry Pi. It provides a simple makefile, a standard lib and setup() and loop() functions.

Installation

In order to install the program so it runs at startup you need to create an entry to rc.local.

#copy program
$ sudo cp ./Program /home/pi/Desktop/Programs/Program

# set rights to execute the file
$ sudo chmod 0777 /home/pi/Desktop/Programs/Program

# test program first
# abort with crtl + c
/home/pi/Desktop/Programs/Program

# open autostart file
$ sudo nano /etc/rc.local
# add the script (above exit 0)
/home/pi/Desktop/Programs/Program </dev/null >/dev/null 2>&1 &

# press ctrl + x and save with y
# reboot your system

# kill the Program
sudo killall Program
