发送诊断命令
on key 'a'{
long Request_Size=0,Req_iter = 0;
byte Req_Buffer[4095];
byte DiagReqBuffer[2] = {0x10,0x01};
diagRequest Door.DefaultSessionControl Req_obj;
Request_Size = elCount(DiagReqBuffer);
write("Request size is %d \n", Request_Size);
writeEx(1,1,"Diag request byte is: ");
diagResize(Req_obj,Request_Size);
for (Req_iter=0;Req_iter<Request_Size;Req_iter++)
{
diagSetPrimitiveByte(Req_obj,Req_iter,DiagReqBuffer[Req_iter]);
writeEx(1,1,"%02x ",DiagReqBuffer[Req_iter]);
}
write("\n");
diagSendRequest(Req_obj);
}
接受诊断命令
on diagResponse *{
byte rsBuf[4095];
int iter=0;
long Response_length=0;
Response_length= DiagGetPrimitiveSize(this);
write("Diag response length is: %d \n", Response_length);
writeEx(1,1,"Diag response byte is: ");
for(iter=0; iter<Response_length; iter++){
rsBuf[iter]=diagGetPrimitiveByte(this,iter);
writeEx(1,1,"%02x ",rsBuf[iter]);
}
write("\n");
}
用到的函数
不换行输出 writeEx(long sink, dword severity, char format[], ...)
sink 指显示在哪个窗口
Values:
-3 Trace Window
-2 Output to the logging file (only in ASC format and if the CAPL node is inserted in the Measurement Setup in front of the Logging Block)
-1 Reserved
0 Output to the System page of the Write Window
1 Output to the CAPL page of the Write Window
4 Output to the Test page of the Write Window
severity Log level 等级
Values:
0 Success
1 Information
2 Warning
3 Error
The parameter severity has no meaning for output to the Trace Window.
diagRequest Door.DefaultSessionControl Req_obj
DefaultSessionControl 是 ECU Door 的默认会话控制对象，此处相当于实例化了一个对象
DiagGetPrimitiveSize 获取诊断请求或者响应部分 Pyload 部分的长度
diagGetPrimitiveByte 按字节获取诊断请求或者响应部分 Pyload 的数据
