There are better ways to model state machines than using spread sheets!

In the past different μC manufacturers have published application notes about the benefit of using state machines for the design of embedded software. An example is the application note SLAA402 from Texas Instruments (TI). It suggests to generate source code based on a spread sheet table. Nowadays several affordable UML modeling tools are available supporting the efficient design of state machines in a graphical way. SinelaboreRT generates production quality source code from state diagrams created with many different UML tools. Give it a try!

Latest Changes


Activity diagram generation from UModel

With this new version 3.6.2 it is now possible to generate code from activity diagrams created with UModel. UModel has support for the basic activity elements such as actions, init - and final nodes.

The microwave oven model microwave_handbook_umodel was extended to show how to use activity diagrams together with state machines in UModel. The example uses a selftest function called at initialisation of the state machine. If the selftest fails the machine enters an error state. The following figures show the extended oven model and a very simple selftest activity diagram.

Download the latest version and give it a try. Activity modelling is a very useful extension to state machine modelling!
