NOTE: It is best practice to ensure sample times are exactly the same all over your model file unless you

specifically need different sample rates in different blocks of your Simulink model. If you must use two

or more different sample times, they must be integer multiples of what you specify as “Fixed step size”.

Choose “Stop time” based on the

amount of time you want to run the

embedded program. For this lab, it

will be a good practice to leave it at

inf (infinite).

Choose Solver options> Type to be

Fixed-Step. Variable Step, the other

option is to simulate continuous

systems and should be chosen only

when the simulation is run in

MATLAB. For all embedded

programs, fixed step should be the

step size. The “Solver” needs to be

set to “discrete (no continuous

states)” unless a continuous time

system is modeled (there may be computational issues with this).

Next, go to Code generation. Under Target Selection> System Target file, click browse to select the file

xpctarget.tlc, as shown in the image below. This will allow the MATLAB compiler to generate executable

code that is compatible for xPC embedded systems ; such as Advantech PC104 computer boards. You

also need to go to xPC target options and deselect ‘Automatically download application after building’;

doing this will stop MATLAB from automatically trying to download the application file to the target

computer (there are errors when multiple targets are connected to the same host). Be sure to click “Apply”

at every step and save all changes. You are now ready to build our first application model and use

Standalone or DOS Loader mode to run them on the PC104 targets.
