The variables pane displays, in the form of a tree view, all of the variables that can be assigned to a control.
It is a list of variables that can be assigned to the controls. All of the variables can be categorized into seven major groups.
- Standard variables
- External inputs
- GPS variables
- Serial variables
- User defined Variables
- Lap timing variables
- Miscellaneous variables
Assigning variables to controls
To associate a variable with a control - i.e. have the control display that variable - drag the variable from the tree and drop it onto the body of the control.
Each and every variable has a set of properties. To make alterations to the variables, click on the property that you wish to edit. This will open up a window that is specific to the property that you wish to alter.
The list of properties is as follows:
The Maximum rate of change option will allow you to set a value which limits how much the variable can change over one second. This can be disabled by setting the value to zero.
You can select a standard transformation relevant to the selected variable from a drop down list.
You can write an equation that will be used to by the VIDEO4 to convert the native values received from the data logger into the value that is shown on screen.
The independent variable x is used to refer to the present variable.
e.g. If you wish to convert a voltage value to mill volts, you can write the following equation.
This is the name assigned to the variable. Name of any variable can be changed to suit with your requirements.
This is a smoothing filter that is used to smooth out any peaks and troughs in the data. Smoothing can be disabled by setting this value to zero.
