CAN

Introduction

CAN is a specification for communication between distributed microcontrollers, especially those embedded in large machines. Data throughput depends on distance and ranges from 125 Kbps (for up to 500 m) to 1 Mbps (for up to 40 m). It is therefore complements the short-range, high-speed communication specifications SPI and I²C.
