一、如何自动生成代码
准备：
.gny——geny工程
.dbc——CAN 信号矩阵
.cdd——诊断文件
.cfg文件——工程文件宏定义
1.1 打开gny文件
1.2 导入dbc文件
根据dbc文件更新can消息
channel0,configurable options,Acceptance Filter Configuration,optimize
Rx Signals编辑，Add需要接收的信号
1.3 导入cdd文件
1.4 导入cfg文件
在configurable options中选择user Config File， 设置生成代码路径
1.5 生成代码
二、借鉴之处
appdesc.c
desc.h 应用层定义
drv_par.h 物理驱动层
nmb_cfg.h 网络管理配置信息
tp_cfg.h 传输层参数配置信息
v_inc.h 定义文件版本
v_par.h 定义软件版本信息
ccl_cfg.h 定义外部接口
基本流程如下：
