常见1553芯片失效故障原因分析

Common 1553 Chip Failure Case Analysis

1553B协议是在航天系统软件研制中经常用到的一种通信协议,在实际应用过程中经常会遇到1553芯片配置正确却不能收发53总线消息的情况。出现这种情况通常是由于1553芯片的变压器接反导致数据总线上的ManchesterⅡ编码错误而引起的。

The 1553 B protocol is a communication protocol often used in the development of model software. In the actual application process, the1553 chip configuration is often encountered but the 53 bus message cannot be sent or received. This situation is usually caused by the Manchester Ⅱ coding error on the data bus caused by the transformer reverse of the 1553 chip.
