CANalysis Documentation

This directory contains all documentation for the CANalysis dual CAN-to-USB interface.

Quick Start

1. Flash the firmware to your PIC32MX795F512L board
2. Connect via USB - device appears as a COM port
3. Use SavvyCAN for professional CAN analysis, or
4. Use any serial terminal for debug commands
