CAN总线是现场总线的一种,在工业自动化领域应用广泛,被誉为自动化领域的计算机局域网。在CAN总线通信中,需要正确设置位定时参数,否则然严重影响CAN的通信效果,甚至根本无法正常通信。本文将结合实例说明CAN位定时参数的计算和设置方法。 CAN bus is a field bus, widely used in industrial automation, known as the computer field of automation LAN. In the CAN bus communication, you need to set the correct bit timing parameters, otherwise it will seriously affect the CAN communication effect, or simply can not be normal communication. This article will combine examples to illustrate CAN bit timing parameters of the calculation and setting method.
