汽车CAN网络的MCU解决方案

　　汽车CAN网络的MCU解决方案

　　汽车工业已经接受诊断总线。这些非常简单、低成本的串行接口允许汽车制造商连接传感器、执行器、电源控制、按钮、开关、显示器、指示器等。过去复杂、昂贵、而且通常不可靠的线束捆绑都已经消失了。

　　这也是专业力学和“自己动手”的福音。低成本的读者可以帮助解决现代汽车和发动机的问题。当它进入汽车的电子设备时，我们可以访问引擎统计数据、实时传感器数据、设置、模式、存储警报和错误代码。

　　许多嵌入式设计利用了这种连接，从低成本的信号传递和拦截（用于远程启动器），通过手持数据终端类型的阅读器，到更复杂的实时数据采集工具，用于赛车和其他高性能应用。

　　As a result， there is a range of microcontrollers， from small 8-bit to high-end 32-bit parts， that target this large and receptive crowd via the CAN bus， a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer. This message-based protocol was designed specifically for automotive applications， but is now also used in areas such as aerospace， industrial automation， and medical equipment.
