When creating a user interface, different user actions send the user interface into different processing segments. State Machines are most commonly used when programming user interfaces.The states in this application might include waiting for user input, performing the measurement, logging the data, displaying the data, and so on. An application that takes one measurement, logs it to disk, and then waits for another user action.The states in this application might include waiting for user input, checking the requested amount against the account balance, dispensing the money, printing the receipt, and so on. For each tab, any actions the user can perform are included in the state. A user initiates state transitions by clicking a particular tab. Each tab of the dialog box corresponds to a state. Use Casesįor example, the following applications can benefit from the state machine pattern: Not only are State Machines advantageous in application planning, they are also easy to create. State diagrams and flowcharts are useful and sometimes essential for the design process. As the complexity of applications grow, so does the need for adequate design. A “shutdown” state can then be used to perform clean up actions.īesides its powerful ability to implement decision-making algorithms, state machines are also functional forms of application planning. The actions performed can depend on previous and current inputs as well as states. Many applications require an “initialize” state, followed by a default state where many different actions can be performed. A State Machine relies on user input or in-state calculation to determine which state to go to next. Each state can lead to one or multiple states and can also end the process flow. State Machines are used in applications where distinguishable states exist. Transition code – determines the next state in the sequence (see Transition Code Examples section below).Shift Register – contains state transition information.Case Structure – each case contains code to be executed for each state.While Loop – continually executes the various states.To translate the state diagram into a LabVIEW programming architecture, you need the following infrastructure: State communication depends on some condition or sequence. Events can be used to trigger moving from one state to the next these can be programmatic events or user-defined, like pressing a button.Įach state in a State Machine does something unique and calls other states. Logical statement help determine when to move to a new state and what state to move to. Decision-making logic that determines when to move to a particular stateĪ state can be defined as the status within the program while accomplishing the overall task of the program examples of states may be initializing, waiting, running a calculation, checking status, etc.This architecture is suitable for applications that can be described as a combination of: A state machine is a programming architecture that allows dynamic flow to states depending on values from previous states or user inputs.
