Summary of PIC18F2455 OBD2 USB TO RS232 CONVERTER CIRCUITS
This project addresses the scarcity of serial ports on modern laptops by creating a USB-to-RS232 converter using the PIC18F2455 microcontroller. Designed as an ISO9141-2/14230-4 ELM323 compatible OBD2 adapter, it facilitates vehicle diagnostics on desktops and notebooks where traditional COM ports are unavailable or unreliable.Parts used in the PIC18F2455 OBD2 USB to RS232 Converter:
- PIC18F2455 microcontroller
- USB connection interface
- RS-232 serial port components
- Hex driver software
- Observation programs
- ISO9141-2 protocol support
- 14230-4 protocol support
