为模型创建 ECU 描述对象。
descObj = coder.asap2.getEcuDescriptions("ASAP2Demo");获取描述对象中可用计算方法的列表。
find(descObj,"CompuMethod")ans = 1×10 string
"ASAP2DemoModelRef_CM_double" "ASAP2DemoModelRef_CM_int16_rpm" "ASAP2Demo_CM_double" "ASAP2Demo_CM_double_m_per__s_2_" "ASAP2Demo_CM_double_rpm" "ASAP2Demo_CM_int32" "ASAP2Demo_CM_single" "ASAP2Demo_CM_single_m_per__s_2_" "ASAP2Demo_CM_single_rpm" "ASAP2Demo_CM_uint8"
过滤计算方法，并获取以 rpm 为单位的计算方法列表。
find(descObj,"CompuMethod",Units='rpm')
ans = 1×3 string
"ASAP2DemoModelRef_CM_int16_rpm" "ASAP2Demo_CM_double_rpm" "ASAP2Demo_CM_single_rpm"
创建和添加自定义计算方法
要向 ASAP2 文件添加新计算方法，请创建一个自定义计算方法。
CompuMethod_1 = coder.asap2.CompuMethod; CompuMethod_1.Name = 'CompuMethod_1'; CompuMethod_1.ConversionType = 'LINEAR'; CompuMethod_1.Coefficients = [2 3]; CompuMethod_1.LongIdentifier = 'longIdentifierTest'; CompuMethod_1.Format = '%2.3'; CompuMethod_1.Units = 's';
将该自定义计算方法添加到 ECU 描述对象中。
add(descObj,CompuMethod_1);
获取新添加的计算方法的属性。
get(descObj,"CompuMethod","CompuMethod_1")
ans =
CompuMethod with properties:
Name: 'CompuMethod_1'
LongIdentifier: 'longIdentifierTest'
Format: '%2.3'
Units: 's'
Coefficients: [2 3]
ConversionType: 'LINEAR'
CompuVTabValues: [1×1 struct]
CustomData: ""
要修改计算方法的属性，请使用 set 函数。将计算方法的 ConversionType 字段更新为 TAB_VERB，并定义 CompuVTabValues。
set(descObj,"CompuMethod","CompuMethod_1",ConversionType="TAB_VERB"); set(descObj,"CompuMethod","CompuMethod_1",CompuVTabValues = struct('Literals',["false" "true"],'Values',[0 1]));
获取属性以查看修改后的字段。
modifiedprop = get(descObj,"CompuMethod","CompuMethod_1")
modifiedprop =
CompuMethod with properties:
Name: 'CompuMethod_1'
LongIdentifier: 'longIdentifierTest'
Format: '%2.3'
Units: 's'
Coefficients: [2 3]
ConversionType: "TAB_VERB"
CompuVTabValues: [1×1 struct]
CustomData: ""
modifiedprop.CompuVTabValues
ans = struct with fields:
Literals: ["false" "true"]
Values: [0 1]
使用更新后的 ECU 描述对象生成 ASAP2 文件，并确认 ASAP2 文件包含计算方法 CompuMethod_1。
coder.asap2.export("ASAP2Demo",CustomEcuDescriptions=descObj);Following Characteristics or Measurements with unsupported data types are not exported in ASAP2 file. "ASAP2Demo_DW.ASAP2DemoModelRef_InstanceData"
删除计算方法
从描述对象中删除新添加的计算方法。
delete(descObj,"CompuMethod","CompuMethod_1");
创建和添加自定义特征
要向 ASAP2 文件添加新特征，请创建一个自定义特征。
Parameter_1 = coder.asap2.Characteristic; Parameter_1.Name = 'Custom_parameter1'; Parameter_1.LongIdentifier = 'longIdentifierParam'; Parameter_1.UpperLimit = 255; Parameter_1.LowerLimit = 0;
将该自定义特征添加到 ECU 描述对象中。
add(descObj,Parameter_1);
获取新添加的特征的属性。
get(descObj,"Characteristic","Custom_parameter1")
ans =
Characteristic with properties:
Name: 'Custom_parameter1'
LongIdentifier: 'longIdentifierParam'
Type: 'VALUE'
EcuAddress: '0x0000'
CompuMethodName: 'NO_COMPU_METHOD'
LowerLimit: 0
UpperLimit: 255
EcuAddressComment: ""
EcuAddressExtension: []
CalibrationAccess: 'Calibration'
DisplayIdentifier: ""
Format: ""
BitMask: []
AxisInfo: []
RecordLayout: ""

set(descObj,"Characteristic","Custom_parameter1",UpperLimit=128)
使用更新后的 ECU 描述对象生成 ASAP2 文件，并确认 ASAP2 文件包含特征 Custom_parameter1。
coder.asap2.export("ASAP2Demo",CustomEcuDescriptions=descObj);Following Characteristics or Measurements with unsupported data types are not exported in ASAP2 file. "ASAP2Demo_DW.ASAP2DemoModelRef_InstanceData"

创建和添加自定义测量
要向 ASAP2 文件添加新测量，请创建一个自定义测量。
Signal_1 = coder.asap2.Measurement; Signal_1.Name = 'Custom_signal1'; Signal_1.LongIdentifier = 'longIdentifierSignal'; Signal_1.UpperLimit = 255; Signal_1.LowerLimit = 0;
将该自定义测量添加到 ECU 描述对象中。
add(descObj,Signal_1);

get(descObj,"Measurement","Custom_signal1")
ans =
Measurement with properties:

BitMask: []
Dimensions: []
Export: 1
MaskData: [1×1 struct]
MaxRefresh: [1×1 struct]
SymbolLink: [1×1 struct]
CustomData: ""
要修改测量的属性，请使用 set 函数。更新测量的 CalibrationAccess 字段。
set(descObj,"Measurement","Custom_signal1",CalibrationAccess='Calibration')
使用更新后的 ECU 描述对象生成 ASAP2 文件，并确认 ASAP2 文件包含名为 Custom_signal1 的测量。
coder.asap2.export("ASAP2Demo",CustomEcuDescriptions=descObj);Following Characteristics or Measurements with unsupported data types are not exported in ASAP2 file. "ASAP2Demo_DW.ASAP2DemoModelRef_InstanceData"
从描述对象中删除新添加的测量。
delete(descObj,"Measurement","Custom_signal1");
创建和添加查找表参数
添加一个查找表参数。
LUT_Parameter = coder.asap2.Characteristic; LUT_Parameter.Name = "custom_lookup_table"; LUT_Parameter.Type = "MAP";
创建轴信息并将其添加到参数中。
axis_data = coder.asap2.AxisInfo; axis_data(1).Name = 'BP3'; axis_data(2).Name = 'Bp4'; axis_data(1).CompuMethodName = 'ASAP2Demo_CM_double'; axis_data(2).CompuMethodName = 'ASAP2Demo_CM_double'; axis_data(1).MaxAxisPoints = '3'; axis_data(2).MaxAxisPoints = '3'; axis_data(1).AxisType = 'STD_AXIS'; axis_data(2).AxisType = 'STD_AXIS'; LUT_Parameter.AxisInfo = axis_data;
将查找表参数添加到描述对象。
add(descObj,LUT_Parameter)
使用更新后的 ECU 描述对象生成 ASAP2 文件，并确认 ASAP2 文件包含查找表参数 custom_lookup_table。
