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; }; }on errorActive
CAN controller goes to ErrorActive.
重要属性，通过this 进行访问
errorCountRX (Receive error counter)
errorCountTX (Transmit error counter)
can (Assign the channel)
on errorPassive
CAN controller goes to ErrorPassive.
重要属性，通过this 进行访问
errorCountRX (Receive error counter)
errorCountTX (Transmit error counter)
can (Assign the channel)
on warningLimit
CAN controller reaches the Warning Limit.
重要属性，通过this 进行访问
errorCountRX (Receive error counter)
errorCountTX (Transmit error counter)
can (Assign the channel)
on busOff
CAN controller goes to Bus Off.
重要属性，通过this 进行访问
errorCountRX (Receive error counter)
errorCountTX (Transmit error counter)
can (Assign the channel)
