Defining Matlab function datatype input in Simulink

Hello,

I have a problem to compile model with following part:

function [delayed_flag, counter] = delayed_flag(flag, counter_default, counter_prev)

    if flag == true
        if counter_prev == 0
            delayed_flag = true;
            counter = uint16(0);
        else
            delayed_flag = false;
            counter = counter_prev - uint16(1);
        end
    else
        delayed_flag = false;
        counter = counter_default;
    end
    
end

The problem seems to be that the 'counter_prev' input is treated as double, and I dont know how to force it to be uint16.

(Error: Data type mismatch. Output port 1 of 'xxx/Unit Delay2' is a signal of data type 'uint16'. However, it is driving a signal of data type 'double'.)

Thank your for help,

Vlasta

In the MATLAB Funciton editor, click icon "Edit Data".

Or in Simulink, Ctrl+H to open Model Explorer, on the left column, navigate to the MATLAB function, find your data and specify the data type.
