Hi All
I'm trying to create my first class and I'm struggeling to define my property as a fixed 'simulink.bus' type. I created a simulink.bus (struct) 'ST_DATARECORD' with (at this moment) 2 variables. I want to use this bus to define the internal property.
classdef myFunct < matlab.System
properties (Access = public)
bCmdAddDataPrevScan uint8 = 0
arrstDataBuffer ST_DATARECORD % Buffer holding the supplied data
nWriteIndex uint16 = 0
end
function obj = mAddData(obj,i_Input)
obj.arrstDataBuffer.variable1 = i_Input; % Copy input data to buffer location
end
end
How to create this? The simulink.bus definition is available in my workspace. The supplied code above is only an example (pseudo) code, so I can understand what to do. Thanks for any anser.
Regards
Ludo

I found an example for a declaration here, but this only displays the default 'double'. How to change this to a 'simulink.bus' type??
classdef ValidationExample
properties
MyPublicData (1,:) double {mustBePositive} = [1 1 1]
end
end

Finally got it to work :-)
The array has now a fixed size of 2 records of the datatype ST_DATARECORD
classdef myFunct < matlab.System
properties (Access = public)
bCmdAddDataPrevScan uint8 = 0
arrstDataBuffer(:,2) = Simulink.Bus.createMATLABStruct('ST_DATARECORD') % Buffer holding the supplied data
nWriteIndex uint16 = 0
end
function obj = mAddData(obj,i_Input)
obj.arrstDataBuffer.variable1 = i_Input; % Copy input data to buffer location
end
end
