## Required packages
```
sudo apt-get update; sudo apt-get upgrade -y
sudo apt-get dist-upgrade
sudo apt-get install bison gcc flex gcc-avr avr-libc
```
## avrdude
```
wget http://download.savannah.gnu.org/releases/avrdude/avrdude-6.2.tar.gz
tar xfv avrdude-6.2.tar.gz
cd avrdude-6.2/

## Changes to `/usr/local/etc/avrdude.conf`
```
programmer
id = "linuxgpio";
desc = "Use the Linux sysfs interface to bitbang GPIO lines";
