Be able to make & upload MagSpoof with variable tracks, to use it without Arduino dependencies, and implement it on the same Raspberry GPIO.

The makefile and the modified MagSpoof library are in my github: https://github.com/salmg/MagSpoofPI

@Sabasacustico added the schematics for the project https://github.com/salmg/MagSpoofPI/tree/master/Schematic open hardware for all.
With the board's schematics and the library working, the initial version of the project is completed. Stay tuned for the next project.

I had the opportunity to be at DerbyCon this year, and I tested the beta of this project updating the tracks using a Samsung Pay token: https://youtu.be/uOlwORnZy7g
To speeding up the uploading process, you will need to sacrifice some functions in the library, for example the "reverseTrack" with less code to upload, faster will be the process, I attached two pic, one with the full code, the other without that function. The difference is around 6 seconds less.
Before
After
I had some issues with the low fuses some time ago. I was trying to upload the MagSpoofPI code using the low fuses for 8mhz(0xe2) in the makefile. It won't run, keep 0x62 for low fuses.
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.
