I have a small circuit board that is part of a larger circuit.
This small circuit board consists of an Tiny45, a resistor and 3 connection pins which link to the larger circuit.
I want to develop my own device for reading these boards using a Raspberry Pi.
Using the multimeter I was able to determine the 3 connection pins as corresponding to Vcc, GND and PB0.
How would I determine the communication protocol and access the information ? Given that there is only one connection could it...
What protocol?
