Hardware is nothing but Pin Finder, needed for Pin Finding. Other parts are basically a smarcard reader inside for protection system and USB -> Serial converter.

Magic is in Software you use, so if you want to develp your own, stop thinking about hardware and start with software.

I have opened some Spiderman Box and found NXP controller in it, with some ROMs, switches.

Basically, every pin finder, as i think, checks pins for RX/TX level voltages, and sequentially puts RX and TX signal to them and tries to read reply.

A successful transmit of data, and then a expected correct reply confirms about RX TX pins.

Just my 2 cents.

Same logic will not applicable with all CPU .

Ok.
So this NXP controller is a microcontroller chip or interface/connectivity chip or data converter? If I am not wrong, then it must be a microcontroller and if it is a MC then the program written in MC is design by Spiderman's author. Correct me if I am wrong. Br Sap Wills
