DifferentCodeSimAndDownload

Introduction

In some cases it is necessary to use different code for simulation and for download.

Simulation icons automatically get ignored for compilation but often to drive the simulation macros you need additional code such as calculations and variables.

It can therefore be useful to separate out the simulation side code so that it does not consume resources for the embedded target.

Setup

First, add Events and Built-in Functions to project explorer, so it will look like this:

You can reduce the width by dragging, but you will lose the titles:

This only requires doing once

The extra UI trees can be added by File > Global Settings > UI Trees tab

Make sure the vents and Built-in Functions are moved to the Project Explorer window:

Creating Event Macros

On the project explorer window click on the Events tab.

Click on + of Simulation to expand.

We are intrestesred in Simulation Start and Stop

Decisions

You can now add the Sim decisions anywhere in your program where Sim and download need to do different things.

As the decision is referring to a property the generated C code is fixed and so the decision code gets optimised out when downloading to a microcontroller.

Here is a Flowcode example file showing the completed functionality.
