Processing Concepts

Instructions to create controls and other elements, data from the controller, code to set properties and variables are placed in the Processing Queue to be processed, normally first-in, first-out.  Keep in mind that strings are treated nearly identical whether they are entered in the Debug/CLI Window, from an interface file holding configuration information, are part of MakerPlot-J's Event Code or are sent from a microcontroller.

•Simple strings for Analog, Digital and Message Data are easily formatted from the controller and easily accessed.

          10,20,30          // Analog String Values accessed with [ain0],[ain1],[ain3],...,[ain99]

          %1000                    // Digital String Values access with [din0],[din1],[din2],...,[din99], MSB to LSB

          Hello World, MakerPlot!  // Message String, comma-separated values accessed with

                                                  // [str0]...[str99]
 

•Instructions are used to perform tasks, for either the environment or for interfaces and control.

          !MakeButton btnTest,50,50,20,5,Test                    // Make a button on the Interface

          !fileWrite myData.txt,[systemTime],Temperature = [ain0]              // Write data to a file

          !fileOpen myData.txt                              // Open a file based on association

          !plot.reset                                        // Reset the plot control

•Setting properties of controls, interfaces (windows), and variables are set in a similar fashion as instructions:
          !metPower.max=50

          !txtVoltage=[ain0]

          !varTemp=[ain2]
 

•Properties of controls and interfaces are easily accessed for use in code.

          !fileWrite test.txt,[metPower],[txtVoltage]

•Interfaces and the canvas control support a wide assortment of drawing instructions for visualizing data with multiple methods of defining colors. Plots also support additional drawing features.

          !drawCircle 50,50,10,RED

•MakerPlot-J supports powerful math operations using both infix (Standard) and Post-Fix math operation combined with accessing data, properties, values and variables.

          !txtValue= { sin(rad([ain0])) }
