Page 12: Programming Environment
Smart quotes are not valid in JavaScript. CodeViewer Application The CodeViewer Application runs as a JavaScript application on the OHV300. The menu driven application has features for changing configuration settings and for defining the applications that run on the reader. -
Page 13: Debugging
Programming Environment Debugging The handheld reader contains a built-in error log that can be used when debugging scripts. To debug the script when an error has occurred, send the ‘(‘ command to the reader; the reader responds by sending the error log to the communications port. The error log may contain messages from the firmware that should be ignored. -
Page 14: Programming Concepts
It is an easy to code and understand application that illustrates how the programming environment works. In its simplest form, the “Hello World!” application in the OHV300 environment sends text to the display. With the following single line of code, you can display “Hello World!” in the screen defined by the standard OHV300 gui object (section 4.1). -
Page 15: The Ohv300 Gui Object
The standard display consists of a status bar, a display area, and labels for the left and right software programmable keys (softkeys) at the top of the OHV300 key pad (see Figure The scroll bar on the right side of the screen indicates the relative position within the displayed object as the operator scrolls through forms, menus, or text using the up and down keys on the keypad. -
Page 16: Softkey Implementation
Programming Concepts 3.2.1 Softkey Implementation Softkeys are general purpose, programmable keys. The softkeys are independent of the GUI display. The gui.showForm, gui.showMenu, and gui.showSubmenu methods include softkey definitions appropriate for the implementation. The following example shows the basic approach to programming the softkeys and implementing their event handlers. -
Page 17: Menus
= "form demo"; // show the form gui.showForm(myForm); When the Form Demo Script runs, the OHV300 displays the following image: Figure 3 – Form Demo Display The user enters an employee number into the edit control and presses the left button (OK) to submit the data. - Page 18 (optional) myMenu.setActiveChild(inventoryApp); subMenu.setActiveChild(capital); // set the caption text for the status bar myMenu.caption = "menu demo"; // show the menu gui.showMenu(myMenu); When the Menu Demo application is initiated, the OHV300 displays the following image: Figure 4 – Menu Demo Display...
-
Page 19: Text
Programming Concepts The Select button sends gui.softkey.enter to run the highlighted application. In this example, the Inventory option is selected. The script then displays the Inventory submenu shown in Figure 5. Figure 5 – Sub Menu Demo Display 3.2.4 Text Use the gui.Text object (section 4.2.3.11) to show text. -
Page 20: Decode Events
Programming Concepts 3.3.1 Decode Events The reader object defines an event onDecode. Section 4.3.2.3 discusses decode events. Example: var numDecodes = 0; var numDecodesProcessed = 0; reader.onDecodeAttempt = function(count) numDecodes = count; numDecodesProcessed = 0; reader.onDecode = function(decode) if( ++numDecodesProcessed < numDecodes ) // process individual decode, save in variables, etc. -
Page 21: Key Events
The clear, enter, and left and right buttons (softkeys) can be programmed to seamlessly integrate with user specific events. The possibilities are shown in Table 1. The GUI objects are documented in section 4.2.3. Figure 6 – OHV300 Keypad 1. Left Softkey 2. Right Softkey 3. -
Page 22: Command Execution
Programming Concepts Object Event Handler Property Any Other Buttons gui.Form onKey gui.Menu onKey gui.Text onKey 3.3.3 Command Execution The reader application defines a number of commands that can be sent to the firmware from the host or by reading codes. The reader (section 4.3) defines an event by the onCommand function. -
Page 23: Symbol Decoding
A decode command from the reader.processCommand method. The reader.onDecode defines an event that allows the application to access data. To program the OHV300 to scan and transmit data, follow the below commands. function onDecode(decode) // Processing reader.onDecode = onDecode;... - Page 24 Programming Concepts Example: function onDecode(decode) data = decode.data; if (decode.symbology == some-special-symbology) data = transformed decode.data; else if (decode.symbology == some-other-special-symbology) data = differently transformed decode.data; if (data matches employee-badge format) loginForm.employeeField.text = decode.data; loginForm.pinField.text = ""; gui.showForm(loginForm); return null; else if (data matches part-number format) stockForm.partField.text = decode.data;...

Page 26: Evaluate Data Format
Programming Concepts 3.5.2 Evaluate Data Format After the data is converted into a common data format based on the symbology, the application determines the data format and processes according to data content. if (data matches employee-badge format) loginForm.employeeField.text = decode.data; loginForm.pinField.text = "";... -
Page 27: Detect Format Errors
Programming Concepts 3.5.3 Detect Format Errors If the format matches a known format that should not be used in the current application context, the application can send a warning message, which is displayed in "warning" form. else if data matches wrong formats warning.text = "bad code for this application";... -
