Original instructions to program Attiny85 from Raspberry Pi: http://www.instructables.com/id/Programming-the-ATtiny85-from-Raspberry-Pi/

Dependencies:

Download and build avrdude

sudo apt-get install bison automake autoconf flex git gcc

sudo apt-get install gcc-avr binutils-avr avr-libc

git clone https://github.com/kcuzner/avrdude

cd avrdude/avrdude

./bootstrap && ./configure && sudo make install

Setup SPI on the GPIO

sudo raspi-config and Enable SPI device in the Advanced Options (see picture) You can check this at the command line with lsmod, no need to reboot. (Maybe need to sudo modprobe spidev)

Download and build WiringPi for the gpio commands

cd ~
git clone git://git.drogon.net/wiringPi
cd wiringPi
./build

MagSpoofPI code integration by Salvador Mendoza Special code for Raspberry Pi implementing avr-gcc without arduino. Main modification in some functions, like digitalWrite(), setup() and loop()

• Example of configuration:
  rbpi - Resistor - attiny85
  19 --> 1k --> PB0
  21 --> 1k --> PB1
  23 --> 1k --> PB2
  DC17 --> n/a --> VCC
  GND20 -> n/a --> GND
  15 --> 1k --> PB5
  Any other pin to enable/disable MagSpoof after be compiled That pin has to be True before "make install" GPIO.setup(pin, 1)

make install
