夜雨聆风
用AI和古法编程写一个解析DBC文件的软件
-
网络节点:描述当前网络有哪些ECU,以BU_开头 如:BU_: Airbag BMS -
报文定义：CAN帧的ID和长度，以BO_开头,如:BO_ 512 VehicleSpeed: 8 ECU_Engine -
信号定义:定义了该信号(车速，模式等)在CAN帧中位置和位宽长度单位.以SG_开头,如SG_ VehicleSpeed: 0|16@0+ (0.01,0) [0|250] “km/h” ECU_BMS,ECU_ESP -
值表:非连续信号的单位吧(挡位,模式等),以VAL_开头,如VAL_ 512 LightStatus 0 “Off” 1 “On” 2 “Error”; -
注释与属性:报文的发送周期等.
-
使用网页前端开发，这样可以免安装 -
有一个加载按钮从本地加载dbc文件 -
解析dbc文件格式 -
显示当前网络的拓扑结构 -
能够导出CSV文件 -
能导出信号节点的每一帧C语言结构体，ECU开发一般是C语言
