Create a block to read keyboard inputs
29 views (last 30 days)
I want to create a block in simulink which prompts me to enter a key & reads ASCII values from keyboard while running a simulation. Input to the block is through keyboard & output is its ASCII value.
I think this can be done either in S-function or embedded matlab function blocks. But I dont know how to use these blocks.
Can someone help???

Drag and drop a Constant block, right click it, select "Block Properties ...", click the "Callbacks" tab, select "OpenFcn", type in the following line,
set(gcbh,'Value',num2str(double(input('Press a key: ','s'))));
Set your model simulation stop time to be inf and run the simulation, while the simulation is running, double click the Constant block, switch to Command window, press a key, observe the output value of the Constant block.

The Embedded MATLAB Fcn block should be sufficient for your purpose. You can use the input function to read inputs from the keyboard.
Here is an example using the Embedded MATLAB Block: Creating an Example Model That Uses a MATLAB Function Block.
