I am trying to create a simulink block that should depend on the base-sample-rate of the model. I tried to put the following in the model-block-tlc file:

%if %<BaseSampleTime> > 0.003
adc1_sum = 0;
for (int i=0; i<8; i++ ) {
   adc1_sum += Get_ADC_Value(11);
  }
%else
adc1_sum= Get_ADC_Value(11)*8;
%endif

But I get: Undefined identifier BaseSampleTime

Is there a way to determine this value in the models tlc-file? (apart from creating a variable when this value is in scope?)

Thanks in advance, Sietse

I do not know of any TLC function to get the base sample time of the model. There is however a list of TLC sample time functions that you may find useful. For instance, the function 'LibBlockSampleTime(block)' allows you to access the sample time of the block.
