I am not using IDL motors patent, I have different coils !

Thanks PCBway for support with board manufacturing ! https://www.pcbway.com/
I love it! I'm trying to replicate this, and found out today (the hard way) you have to program the ATTiny before soldering the MOSFETS, otherwise the programmer will state: "avrdude: error: usbasp_transmit: Broken pipe".
Also, you have to add:
#include <avr/io.h>
#include <stdint.h>
to the top of the program for it to compile in Arduino.
And not all programmers support the "TPI" (Tiny Programming Interface) of ATTinys (e.g. USBisp), keep that in mind when trying to flash.
So far, no movement though. The ATTiny doesn't seem to be pushing out signals.
