TwaiTaskBased Library - ESP32-C6

A FreeRTOS task-based wrapper for TWAI (Two-Wire Automotive Interface) CAN communication on ESP32-C6 microcontrollers.

Overview

This library provides a clean abstraction for handling TWAI/CAN bus communication using FreeRTOS tasks, enabling efficient, non-blocking communication in multi-threaded ESP32 applications.

Features

• Task-Based Design: Runs TWAI communication in separate FreeRTOS task
• Non-Blocking: Doesn't block main application logic
• Thread-Safe: Proper synchronization for concurrent access
• Configurable: Flexible setup for different CAN bus configurations
• ESP32-C6 Optimized: Designed for ESP32-C6 microcontroller

Installation

Using PlatformIO

Add to your platformio.ini:

lib_deps =
    git@github.com:trailcurrentoss/Esp32C6TwaiTaskBasedLibrary.git@0.0.3

Manual Installation

1. Clone or download this library
2. Copy to your project's lib/ directory
3. Include in your sketch:

#include <TwaiTaskBased.h>

Quick Start

#include <TwaiTaskBased.h>

void setup() {
  Serial.begin(115200);

  // Initialize TWAI with task-based handling
  // (Configuration details in header file)
  TwaiTaskBased::init();
}

void loop() {
  // Your application code here
  // TWAI communication runs in background task
  delay(1000);
}

Configuration

See include/TwaiTaskBased.h for detailed configuration options including:

• CAN bus speed (250kbps, 500kbps, 1Mbps, etc.)
• GPIO pin assignments
• Task priority and stack size
• Filter settings

Hardware Requirements

• ESP32-C6 microcontroller
• CAN transceiver module (SN65HVD230, etc.)
• Appropriate GPIO pins for TWAI TX/RX
