The only necessary changes in the original MagSpoof design to work with this project:

-Remove the button and replaced it with a 10k resistor.

I will use Raspberry Pi pin numbers(board numbers), NOT GPIO numbers to describe this instructions.

We will need four 1k resistors, connecting the Raspberry pins:

-Raspberry pin 15 as reset button, to the Attiny’s PB5.
-Raspberry pin 19(MOSI) to PB0.
-Raspberry pin 21(MISO) to PB1.
-Raspberry pin 23(SCK) to PB2.

Then connecting the Raspberry Pi GND(pin 25) to Attiny’ GND and Raspberry DC power 3.3(pin 17) to Attiny’s VCC. Example:

The pin 7 will help to control(on/off) the MagSpoof after a succeed installation of MagSpoofPI. So the end user will be able to enable/disable the MagSpoof without removing it from the Raspberry PI GPIO. So the pin 7 is connected to a 10K resistor. The another end of the resistor to GND.

Completed configuration example:

After this, you can find the instructions to install the MagSpoofPI library in the github repository.
