CAPL创建与语法简介

本文主要是介绍CAPL创建与语法简介，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

CAPL 语言和C语言基本语法很相似，只是没有指针，list, set 等概念。

如何通过CANOE 创建自动测试节点

1. 创建一个CANoe configuration

2. 点击viewàSimulation Setup

3. 点击右键->insert xml test moudle

4. 右键点击新创建的XMLNode->Configuration

5. Test Script添加Test CaseXML

6. 点击TAB Components 进行创建或添加Test case files(.can)

7. 点击确认返回

8. 右键XML NODE->Edit *.can 进行编辑Test Casefile(.can)

整体结构

通过CAPL 语言编写的测试用例与方法需要以 .can 为扩展名的文件打开

属性页

Includes

同C语言中Includes 一样，可以包含其他.can文件，进而引用其他文件的内容

Variables

全局变量定义区域，主要分为以下几种类型

Integers

Ø byte

Ø word

Ø dword

Ø int

Ø long

Ø qword

Ø int64

Floating point numbers

Ø float

Ø double

Individual characters

Ø char

Map

float m[float];

m[4.1] = 5.5; //key is 4.1 (float) and value is 5.5 (float)

m[5.3] = 6.6;

write ("4.1 is mapped to %2.2lf",m[4.1]);

write ("5.3 is mapped to %2.2lf",m[5.3]);

for (float mykey : m)

{

write("%2.2lf is mapped to %2.2lf.", mykey, m[mykey]);

}

Enum

和C语言定义Enum 类型一致

Struct

和C语言定义结构体类型一致

注意：结构体属性只能是基本数据类型，不能是message类型，即使编译不存在问题

Message

Error Frame

System

与System相关的事件触发器

可以通过CANBrower 添加System事件触发器

CAN

与CAN相关的事件触发器

可以通过CANBrower 添加CAN 事件触发器

on message

The event procedure on message is called onthe receipt of a valid CAN message.

如何定义 message 事件触发

on message 123	React to message 123 (dec, standard identifier), regardless of receiving chip
on message 123x	React to message 123 (dec, extended identifier), regardless of receiving chip
on message 0x123	React to message 123 (hex, standard identifier), regardless of receiving chip
on message 0x123x	React to message 123 (hex, extended identifier), regardless of receiving chip
on message EngineData	React to message EngineData
on message CAN1.123	React to message 123 if it is received by CAN1 chip
on message *	React to all messages
on message CAN2.*	React to all messages received by CAN2 chip
on message 0,1,10-20	React to messages 0, 1 and 10 through 20

如何判断收到message 类型

on message * {
if (this.DIR == RX) {
write("This is RX message");
}
if (this.DIR == TX) {
write("This is TX message ");
}
}

on errorFrame

The event procedure on errorframe is calledwhen an error state (Error Frame) occurs on the bus.

如果通过errorcode进行区分

on errorFrame
{
   switch (this.ecc & 0x20)
   {
      case (0x20): // in case of reception error
         write ("%d Ch %dRxErr", this.time, this.can);
         return;
      case (0): // in case of transmission error
         write ("%d Ch %dTxErr", this.time, this.can);
         return;
   };
}
