APD is implemented to preserve battery life by turning the calculator off after about four minutes of inactivity.
Applications can use the link port for transferring data on two different levels. These data lines are accessed through the B-port of the Z Page See the System Routine Documentation for more details. Page Chapter 2: TI Plus Specific Information Example one: The following routine is called to do a spot check of the link port for activity for a single byte of data being sent.
Page This sample routine will attempt to send the register pair HL over the link port. A macro is used to install the error handler Page Modify the error code to remove the GoTo option and have the system report the error with only a Quit option. Example one: Do not allow the error to be reported by the TI Plus. The last error handler initiated will be notified of any error that occurs. When the first handler is notified of the error, none of the previous handlers initiated are notified.
If neither of these modes is set, then these functions will generate an error when the arguments input would produce a complex result. Page Complex Math Chapter 2: TI Plus Specific Information The floating-point math routines described in the previous sections will always return an error when the result is a complex number. To have floating-point math routines return the complex result, the routines described in Other Math Functions need to be used. It also covers accessing math functions not listed in the above sections.
Many of the functions in the previous two sections can also be used with arguments other than RealObj and CplxObj. Using the TI Plus, equations can only contain functions that return values. Programming commands and other commands that do not return a result to Ans are not valid in expressions, and therefore can only be executed from a program variable.
Install an error handler around the parsing and the storing routine to catch any errors. Page Temporary Variables It needs to be completely or partially reset periodically in order to keep temporary variable usage available. The Managing Temporary Variables section provides additional details. This will delete all temporary variables and reset pTempCnt equal to h. Most applications should be able to use the CleanAll routine to manage temporary variables.
Applications should make a call to the CleanAll routine as soon as all temporary variables in use are no longer needed. This is especially important if temporary variables are going to be created in a looping environment.
Applications can take advantage of the language setting by being able to modify their output to match the current language setting, if desired. The application will also not be notified if the user turns the unit off. This means that no data, not already saved in a variable, will be lost when the unit turns off.
Some of the calls in this sequence are not always needed — see the comments. The following sequence exits the application cleanly even if the hardware stack is not at the same level upon entry to the application. Page Stand-Alone With Put Away Notification If an application needs to be notified when it is being closed down by the system, it must change the system monitor vectors. Only applications that are extensively integrated with the TI Plus system need to use the monitor.
These types of applications are currently not fully supported by this document. Page Since the monitor is not in control, information will be sent to the application under three circumstances. While GetKey link activity is detected. If a system error is generated and allowed to be displayed, the Quit option is chosen by the user. Page Put Away Code ; note: this will terminate the link activity that caused the application ; to be terminated. A simple application is used to walk you through the detailed steps.
Use the chart as a general guide. This process assumes that you are running Windows 95 operating system and that you have access to a text editor such as Notepad. The final layer in the TI Plus architecture is the Programming layer. This chapter is primarily concerned with applications. The This data is known as the application header. The application header contains information used by the calculator operating system when the user tries to run the application.
It uses a floating-point format that requires up to 11 bytes in certain situations. Since floating- point operations are so common, it defines six byte areas that it uses frequently for storing such numbers. The example found in the hello. Page Branch Table Placement When an on-page call, a call to a routine that exists on the same application page as the point of the call, is made, the normal call opcode should be used.
