基于Microchip单片机及收发器实现的低成本LIN总线

Achieving low cost LIN bus based on MCU and transceiver of Microchip

介绍了几款Microchip单片机及收发器实现低成本的汽车子网LIN总线节点。基于Microchip单片机内带的增强型通用同步/异步收发器(EUSART)实现LIN的控制器,并用Microchip的MCP2021作为LIN的电平转换器,最终实现一主多从的低成本的LIN网络。

This article introduces several Microchip＇s MCUs and transceiver to achieve low cost of LIN bus notes in auto sub network. It also introduces how to use Microchip＇s MCU within enhanced universal synchronous asynchronous receiver transmitter （EUSART） to achieve LIN＇s controller,and how to use Microchip＇s MCP2021 as LIN＇s level transceiver. Finally, we can construct one master note and many slave notes, to achieve low cost LIN network.
