When Alex connects this Arduino to the OBD-II port of a car and sends a "Read VIN" request from a genuine J2534 tool on the laptop, the Arduino prints:
Alex realizes the Arduino cannot be a J2534 device. It is too slow, too simple, and lacks the USB stack to emulate a Windows driver. But it can speak the language underneath J2534: raw CAN frames.
An Arduino runs a single void loop() .
J2534 devices are sophisticated. They contain high-speed microcontrollers, large buffers, and precise timing circuits. They cost hundreds of dollars.
