CAN Wizard

CAN Wizard is a project designed for communication using the CAN (Controller Area Network) protocol, primarily targeted at embedded systems utilizing the ESP32 microcontroller family. This project is developed using ESP-IDF and supports ESP32-C3, allowing flexible development for different use cases.

• Xa6p Article. (in Russian)
• Traduccion in English.

Features

• CAN Communication: Implements CAN communication protocols, enabling data exchange between devices over a CAN bus.
• File System Integration: Includes file system operations for handling configuration or logging.
• Custom serial Console: A custom serial console implementation for interacting with the system and issuing commands.
• Modular Design: Organized in components for easier maintenance and scalability, including linked lists and command utilities.

Requirements

• Hardware:

  • ESP32-C3 microcontroller
  • SN65HVD230 CAN transceiver

• Software:

  • ESP-IDF (version x.x.x or newer)
  • CMake (for project build system)
  • Python (for ESP-IDF and related tools)

Setup and Installation

1. Clone the Repository: Clone this repository using:

   git clone --recursive git@github.com:okhsunrog/can_wizard.git
   

2. Install ESP-IDF: Follow the official ESP-IDF installation guide for your operating system: ESP-IDF Setup Guide

3. Configure ESP-IDF: Set up your environment by running the following commands:

   cd <project-directory>
   idf.py set-target esp32c3
   idf.py menuconfig
   

4. Build and Flash: Build the project and flash it to your microcontroller:

   idf.py build
   idf.py flash
   idf.py monitor
   

Usage

Console Commands

The CAN Wizard project provides several commands that can be executed through a console interface:

• can_send <data>: Send CAN data over the bus.
• can_receive: Receive CAN data from the bus.
• can_status: Display the current CAN status.

Additional commands can be explored through the console by typing help.

File System Operations

The project includes basic file system operations to read and write configuration or log files. These operations can be accessed through the fs_* commands in the console.
