USB OBD2 Adapter Based on PIC18F2455

This project is build around one of new Microchip PIC18F2455/2550 8-bit microprocessor with USB support. The PIC18F2455 USB core is V1.1 and V2.0 compliant and operates at 1.5 Mb/sec and 12Mb/sec speeds respectively. The microprocessor has 2048 bytes of RAM and 24K of Flash program memory, which is plenty for implementing the OBD2 controller functionality using high-level C programming language.
