Macro Examples and Mini-Apps

The following macros and mini-apps are included with Daqarta. Most of them have macro IDs (shown in parentheses), allowing them to be invoked as hot-keys by hitting the F8 key, then the ID character.

You can open the Help topic for any included macro by selecting it in the Macro List and clicking the Help button below the list, next to Run. If you click the Edit button to see the macro definition, you'll find a duplicate Help button near the upper right. For those macros that open a Custom Controls dialog when running, or display a custom macro message or Custom Meter, you can usually right-click on those to open the same Help topic.

Note that many of these macros, especially those with Custom Controls, call other macros as subroutines. Most don't appear in the list below, but are discussed under the topics that invoke them. They have descriptive names that start with an underscore; for example, _Engine_Ctrls is a subroutine to handle the Custom Controls used by Engine_Sim, the engine crank and cam sensor simulator.

Macros like _Color_Tint (listed below) are general-purpose subroutines called by the Pulse Meter and Multiple Meters, and can be used by your own macros as well.

Due to the leading underscore, subroutines appear at the bottom of the Macro List. Since they are normally not to be activated directly by the user, this keeps them out of the way.
