## 快速开始
|
||
|
||
### 环境要求
|
||
|
||
- Python 3.8+
|
||
|
||
### 安装
|
||
|
||
将 `src` 目录添加到 Python 路径即可使用：
|
||
|
||
```python
|
||
import sys
|
||
sys.path.insert(0, '/path/to/arxml_sdk/src')
|
||
```
|
||
|
||
或直接使用相对导入：
|
||
|
||
```python
|
||
from src import create_arxml_document, write_arxml
|
||
```
|
||
|
||
### 最小示例
|
||
|
||
```python
|
||
from src import (
|
||
create_arxml_document, write_arxml, create_package,
|
||
create_base_type, Category, Encoding
|
||
)
|
||
|
||
doc = create_arxml_document()
|
||
base_type = create_base_type("UInt8", size=8, encoding=Encoding.TWO_COMPONENT)
|
||
package = create_package("MyPackage", elements=[base_type])
|
||
package_element = package.to_arxml(doc)
|
||
doc.documentElement.appendChild(package_element)
|
||
write_arxml(doc, "minimal.arxml")
|
||
```
|
||
|
||
---
|
||
|
||
## 基础类型创建
|
||
|
||
### 创建基本整数类型
|
||
|
||
```python
|
||
from src import create_base_type, Category, Encoding
|
||
|
||
uint8 = create_base_type("UInt8", size=8, encoding=Encoding.TWO_COMPONENT)
|
||
uint16 = create_base_type("UInt16", size=16, encoding=Encoding.TWO_COMPONENT)
|
||
sint8 = create_base_type("Sint8", size=8, encoding=Encoding.TWO_COMPONENT)
|
||
float32 = create_base_type("Float32", size=32, encoding=Encoding.IEEE754)
|
||
```
|
||
|
||
### 创建带文本表的类型
|
||
|
||

|
||
from src import (
|
||
create_base_type, create_unit, create_data_constraint,
|
||
create_linear, create_text_table, create_compu_method,
|
||
Category, LowerSts, UpperSts
|
||
)
|
||
|
||
unit = create_unit("km/h", display="km/h", factor=1.0, offset=0.0)
|
||
|
||
constraint = create_data_constraint(
|
||
"SpeedConstraint",
|
||
lower=0, upper=250,
|
||
lower_sts=LowerSts.CLOSED,
|
||
upper_sts=UpperSts.OPEN
|
||
)
|
||
|
||
linear = create_linear(factor=0.01, offset=0)
|
||
|
||
compu = create_compu_method(
|
||
"SpeedConversion",
|
||
unit=unit,
|
||
linear=linear,
|
||
category=Category.LINEAR
|
||
)
|
||
|
||
value_type = create_value_type(
|
||
"Speed",
|
||
unit=unit,
|
||
compu_method=compu,
|
||
data_constraint=constraint
|
||

arguments=[
|
||
ClientServerInterface.Argument(
|
||
name="config",
|
||
direction=PortDirection.IN,
|
||
data_type=create_value_type("Config", unit=unit)

|
||
|
||
## 软件组件
|
||
|
||
### 创建组件

SenderReceiverInterface, create_sender_receiver_interface,
|
||
AtomicType, ComponentType
|
||
)
|
||
|
||
interface = create_sender_receiver_interface("DataInterface")
|
||
port = PPortPrototype(name="DataPort", interface=interface)
|
||
|
||
component = ApplicationSwComponentType(
|
||
name="SensorComponent",
|
||
supports_multiple_instantiation=False,

||
from src import SwComponentType, ComponentType, AtomicComponentType, CompositionSwComponentType
|
||
|
||
child1 = ApplicationSwComponentType(name="Child1")
|
||
child2 = ApplicationSwComponentType(name="Child2")
|
||
|
||
composition = CompositionSwComponentType(name="Composition")
|
||
composition._component_type = ComponentType.COMPOSITION
|
||
```
|
||
|
||
---
|
||
|
||
## 内部行为
|
||
|
||
### 创建 Runnable 和事件
|
||
|
||
```python
|
||
from src import (
|
||
SwcInternalBehavior, RunnableEntity, TimingEvent, InitEvent,
|
||
VariableAccess, create_swc_internal_behavior, create_runnable_entity,
|
||
create_timing_event, create_init_event, create_data_received_event
|
||
)
|
||
|
||
runnable = create_runnable_entity(
|
||
name="UpdateMeasurement",
|
||
symbol="UpdateMeasurement",
|
||
minimum_start_interval=0.01
|
||
)
|
||
runnable.add_variable_access(
|
||
VariableAccess(name="SpeedAccess", port_prototype_ref="SpeedPort")
|
||
)
|
||
|
||
timing_event = create_timing_event(name="Timing_10ms", period=0.01)
|
||
init_event = InitEvent(name="Init", runnable_ref="UpdateMeasurement")
|
||
|
||
data_rx_event = create_data_received_event(
|
||
name="DataReady",
|
||
data_element_ref="ReadyFlag",
|
||
period=0.05
|
||
)
|
||
|
||
behavior = create_swc_internal_behavior(
|
||
name="SensorBehavior",
|
||
runnable_entities=[runnable],
|
||
events=[timing_event, init_event, data_rx_event]
|
||
)
|
||
|
||
component = ApplicationSwComponentType(name="Sensor")
|
||
component.internal_behavior = behavior
|
||
```
|
||
|
||

|
||
|
||
## 打包与导出
|
||
|
||
### 基本导出流程
|
||
|
||
```python
|
||
from src import (
|
||

|
||
get_ar_packages_element, add_package_to_document,
|
||
create_base_type, create_value_type, create_unit
|
||
)
|
||
|
||
doc = create_arxml_document()
|
||
packages_element = get_ar_packages_element(doc)
|
||
|
||
base_type = create_base_type("UInt8", size=8)
|
||
app_type = create_value_type("AppData")
|
||
package = create_package("MyPkg", elements=[base_type, app_type])
|
||
|
||
package_element = package.to_arxml(doc)
|
||
add_package_to_document(doc, package_element)
|
||
|
||
write_arxml(doc, "output.arxml")
|
||
```
|
||
|
||
### 格式化输出
|
||
|
||
```python
|
||
from src import write_arxml_pretty
|
||
|
||
write_arxml_pretty(doc, "output_formatted.arxml")
|
