  3. CANdevStudio

    Development tool for CAN bus simulation

  4. arduino-mcp2515

    Arduino MCP2515 CAN interface library

  5. Seeed_Arduino_CAN

    Seeed Arduino CAN-BUS library - MCP2518FD&MCP2515&MCP2551

  6. MCP_CAN_lib

    MCP_CAN Library

  7. RejsaCAN-ESP32

    ESP32 and ESP32-S3 board with CAN interface, runs on 12V power (with auto shutdown)

  8. arduino-canbus-monitor

    Can bus monitoring tool based on arduino and can bus shield. Implements CAN ASCII/SLCAN protocol compatible with Lawicel CAN232/CANUSB. Can be used for monitoring low speed CAN (interior can bus of most cars, less than 500kbps). For higher speeds serial port can become a bottleneck in case data density is high.

  9. can-utils

    A C++ DBC file parser, and a CAN telemetry tool (by mireo)

  10. acan-esp32

    An ESP32 CAN 2.0B library

  11. esp32-can-iot

    A ESP32 based interface between CAN-bus and IoT environments.

  12. SLSS-CANAnalyser

    SLSS CANAnalyser is Windows CAN-Bus-Analysis-Software to show, record and evaluate CAN-Bus signals / data. For the connection with the CAN-Bus System SLSS CANAnalyser uses one or more Arduino Micro-Controller with installed MCP2515-CAN Boards.

NOTE: The open source projects on this list are ordered by number of github stars. The number of mentions indicates repo mentiontions in the last 12 Months or since we started tracking (Dec 2020).
