it's a fork of Arduino MCP2515 CAN interface library Adapted for use on esp32/esp8266. CAN-BUS is a common industrial bus because of its long travel distance, medium communication speed and high reliability.

2023年12月20日 · 本文详细介绍了如何在ESP32上进行CAN通信，包括ESP32的TWAI外设、第三方CAN库的查找与安装，硬件准备与连接，以及代码调试步骤。 特别提到了MCP2515和SJA1000芯片在CAN通信中的作用，以及CAN波特率设置的注意事项。

2025年2月2日 · In this tutorial, we will explore the CAN Bus communication protocol by interfacing the MCP2515 CAN Bus Module with ESP32 microcontroller. Our objective is to transmit data from a DS18B20 temperature sensor over a specified distance using the CAN protocol.

ESP32 MCP2515 CAN interface library in C, for ESP-IDF framework. it's a fork of MCP2515 CAN interface library in C++ for ESP-IDF. CAN-BUS is a common industrial bus because of its long travel distance, medium communication speed and high reliability. It is commonly found on modern machine tools and as an automotive diagnostic bus.

Arduino library for MCP2515, it's available for most of theArduino boards, we test it with Arduino UNO, Leonardo, Mega as well as Zero. With this library, you can, Set the masks and filters, there're 32 masks and filters. /examples - Example sketches for the library (.ino). Run these from the Arduino IDE.

在之前文章 CAN BUS 通訊研究 中, 利用了MEGA2560+MCP2515去做CAN BUS上接收和傳送資料. 最近看到一篇文章 可以用ESP32去做CAN BUS上的sniffer來分析. CANHacker 參考 https://github.com/autowp/arduino-canhacker install library 其中是想利用他的windows端的軟體 CANHackerV2.00.01.exe 來做CAN bus analyzer

2025年2月7日 · In this blog, we will explore CAN communication, its applications, CAN bus messages, and how to interface an ESP32 with an MCP2515 CAN controller module for real-world projects.

2023年11月13日 · The ESP32 processor, combined with its two SPI connections, can control up to six CAN Bus controllers. Add the internal controller, and you get seven.

2025年2月27日 · The MCP2515 and MCP2517/18 are CAN (Controller Area Network) controllers that enable the ESP32 to interface with CAN networks. The MCP2515 operates over SPI, while the MCP2517/18 offers an enhanced SPI interface with FIFO buffering for higher performance. The MCP2515 requires an external CAN transceiver (e.g., TJA1050) and is connected as follows:

2019年7月4日 · Is it possible to connect 2 or more MCP2515 CAN controllers with 1 ESP32 SPI and just control thru different SC pins? Anybody has suggestion which library to use?
