Watch panel


This panel displays the content of a registered watch-expression or changes the displayed value (see "2.11.6 Displaying and changing watch-expressions").

Up to four instances of this panel can be opened at a time. Each panel is discriminated by the name "Watch1," "Watch2," "Watch3" or "Watch4" in the title bar, allowing you to register, delete or move a watch-expression independently of the panel.

Watch-expressions can also be registered from the Editor panel, Disassemble panel, Memory panel, CPU Register panel, Local Variables panel or IOR panel, as well as from this panel.

If a panel that has watch-expressions registered in it is closed, the panel is hidden, but information on its registered watch-expressions is retained. (When the panel is reopened, it opens, with those watch-expressions registered in it as they were.)

When the value of any watch-expression changes after the program is executed, the display is updated. (During step execution, the display is updated successively as the program is stepped through.)

Also, if the Realtime display update function is enabled, the display of values can be updated in real time, even during program execution.

Note that this panel can only be opened when CS+ is connected with the debug tool.

Caution

It is not possible to display or change the CPU register contents during program execution.

Remark

By double-clicking a line delimiting each area on the panel, it is possible to change the relevant area to the smallest displayable width without omitting the content in it.

Figure A.13

Watch Panel

 

This section describes the following.

[How to open]

-

Choose [Watch] from the [View] menu and then select [Watch1-4].

[Description of each area]

(1)

[Watch] area

This area displays registered watch-expressions in list form.

By clicking the table title part of this area, it is possible to sort the watch-expressions in the list in alphabetical order.

Also, it is possible to create a category (folder) as desired and display the watch-expressions, as classified by category, in tree form (see "(a) Editing a tree").

The meaning of each displayed icon is as follows:

 

Indicates a state that the watch-expressions belonging to this category are displayed. When you double-click the icon or click the "-" mark, the category is closed to hide the watch-expressions.

 

Indicates a state that the watch-expressions belonging to this category are hidden. When you double-click the icon or click the "+" mark, the category is opened to display the watch-expressions.

 

Indicates that the watch-expression is a variable.

The watch-expression indicating an array, pointer type variable or a structure/union is marked with a "+" or "-" at the beginning, so that when the sign is clicked, the expression expands or collapses (see “(b) Expanding/collapsing the display”).

 

Indicates that the watch-expression is a function.

 

Indicates that the watch-expression is an immediate.

 

Indicates that the watch-expression is an expression.

 

Indicates that the watch-expression is an I/O register.

 

Indicates that the watch-expression is a CPU register.

The watch-expression having a lower level register (part of a register) is marked with a "+" or "-" at the beginning, so that when the sign is clicked, the expression expands or collapses (see “(b) Expanding/collapsing the display”).

 

This area has the following features:

(a)

Editing a tree

Watch-expressions can be classified by category (folder) for display in tree form.

To create a new category, move the caret to the position where you want to create and click the button in the toolbar or select [Create Category] on the context menu, and then enter any category name.

If the need arises to delete a category, select the category you want to delete, click the button in the toolbar or select [Delete] on the context menu.

Also, if you want to edit a category name you created, select the category name you want to edit and follow one of the following methods:

-

Click the category name again and then edit it directly from the keyboard.

-

Choose [Rename] from the [Edit] menu and then edit the category name directly from the keyboard.

-

Press the [F2] key and then edit the category name directly from the keyboard.

 

After creating a category, drag-and-drop the registered watch-expressions into the category. The watch-expressions are displayed in tree form classified by category.

Similarly, the order in which categories or watch-expressions are displayed (one above or below the other) can be changed as desired by a drag-and-drop operation.

Caution 1.

No other categories can be created within a category.

Caution 2.

Up to 64 categories can be created in one Watch panel. (If an attempt is made to create more categories exceeding this limit, a message is displayed.)

Remark

If categories or watch-expressions in a Watch panel are drag-and-dropped into another Watch panel (Watch1 to Watch4), the categories or watch-expressions are copied into the target Watch panel.

(b)

Expanding/collapsing the display

The watch-expression indicating an array, pointer type variable, a structure/union/class or a register (only those that bear a name representing a part) is marked with a "+" at the beginning, so that when you click the sign, the next entry is expanded for display (when expanded, the sign changes to a "-").

Watch-expression

Contents when expanded

Array

All elements in an array.

They can be displayed as a character string by selecting [Notation] and then [ASCII] on the context menu (up to 256 characters displayable).

However, if not displayable because of encoding type, a "." or "?" is displayed.

Pointer type variable

A variable at the destination pointed to by a pointer.

Structure/union/class

All members of a structure/union/class.

Register

The name of a bit or bit string that comprises a register.

Example: For PSW register

IPL register, PM register, U register, I register, O register, S register, Z register, C register

(c)

Registering a new watch-expression

There are following three methods of registering a new watch-expression.

<1>

Registering a watch-expression from another panel

On another panel, perform one of the following operations on the subject that you want to register as a watch-expression:

-

Select the subject character string and then drag-and-drop it directly into this area on any Watch panel (Watch1 to Watch4) (except for the Editor panel).

-

Select the subject character string or move the caret to one of subject character strings (the subject being automatically selected), and then select [Register to Watch1] on the context menu.

-

Choose [Copy] from the [Edit] menu to copy the subject character string and then choose [Paste] from the [Edit] menu in this area on any Watch panel (Watch1 to Watch4).

 

The table below shows the relationship between the panels for which this operation is possible and the subjects that are registrable as watch-expressions.

<2>

Direct registration on Watch panel

On any Watch panel (Watch1 to Watch4), click the button in the toolbar or select [Add New Watch] on the context menu. An entry box for new watch-expressions is displayed at the bottom of this area.

In the [Watch] area of the entry box, enter a watch-expression directly from the keyboard and then press the [Enter] key.

The form in which watch-expressions are entered this way is as follows:

Note 1.

It represents C89, C99 and C++ variables.

Note 2.

To specify a member variable of base class, specify scope before a member name.
(Example: variable.BaseClass::member)

Note 3.

If a label name or EQU symbol name contains a "$," enclose the name in braces "{ }."
(Example: {$Label})
If there is an imaginary number, multiply it by the uppercase letter "I" (example: 1.0 + 2.0*I). The letter "I" constitutes a keyword, so that when you specify "I" of a CPU register, add ":REG" (example: I:REG).

 

Also, scope can be specified for a watch-expression when it is registered. When a watch-expression is registered by specifying scope, it is handled as shown below.

Note 2.

A search is made for static functions and global functions from the scope of the current PC value in that order. Static functions out of scope are not searched for.
To specify a function defined in a name space, do not write scope. (Example: Scope::func)
Also, if functions with the same name exist, write the type of parameter expressly. (Example: func(int, int))

Note 2.

To specify a function and variable defined in a name space, be sure to write scope. (Example: Scope::func)
Also, if functions with the same name exist, write the type of parameter expressly. (Example: func(int, int))

Note 3.

If the current PC value exists in a specified function, the local variables that are not declared as static also comprise the subject to be searched.

Note 4.

A search is made for local variables, static variables inside a file and global variables from the scope of the current PC value in that order. The local variables and the static variables inside a file that are out of scope are not searched for.

Remark 1.

A symbol name at the current caret position can be supplemented by pressing the [Ctrl] and [Space] keys together in this area. (See "2.21.2 Symbol name completion function.")

Remark 2.

Immediates are handled as a numeric value. Also, operators can be used for immediates.

Remark 3.

Arithmetic expressions using a symbol can be specified as watch-expressions.

Remark 4.

If there exist a C/C++ variable, a CPU register and an I/O register with the same name that are registered without specifying scope, the symbols are resolved in the order given below, to display values.
C/C++ variable > CPU register > I/O register

Remark 5.

If there exist a local variable and a global variable with the same name that are registered by only a symbol name without specifying scope, the symbols are resolved based on the scope of the current PC value, to display values.

Remark 6.

If a watch-expression is registered from the IOR panel or CPU Register panel, the watch-expression will have scope specification automatically added to it.

Remark 7.

If the letter "I" alone is specified as a watch-expression, it is interpreted as an imaginary keyword. To acquire the value of a register "I," add ":REG" after the register.

<3>

Registering from another application

Select a character string representing a C/C++ variable, CPU register, I/O register or assembler symbol from an external editor or the like, and then perform one of the following operations:

-

Drag-and-drop the subject character string into this area on any Watch panel (Watch1 to Watch4).

-

Copy the subject character string to the clipboard and then select [Paste] on the [Edit] menu in this area on any Watch panel (Watch1 to Watch4).

Caution 1.

Up to 128 watch-expressions can be registered in one Watch panel. (If an attempt is made to register more watch-expressions exceeding this limit, a message is displayed.)

Caution 2.

In a block where a variable that is the subject of operation is not used, variable data may not always exist in the stack or register, due to optimization by a compiler. In this case, even when a variable that is the subject of operation is registered as a watch-expression, the displayed value remains marked with "?."

Remark 1.

Watch-expressions registered on each Watch panel (Watch1 to Watch4) are managed separately from each other and are saved as user information on the project.

Remark 2.

More than one watch-expression with the same name can be registered.

(d)

Editing a watch-expression

To edit a registered watch-expression, double-click the subject watch-expression to put it into edit mode and then enter the content of editing directly from the keyboard. (Pressing the [Esc] key cancels the edit mode.)

When you've finished editing a watch-expression, press the [Enter] key to complete the editing.

(e)

Deleting a watch-expression

Click the button in the toolbar or select [Delete] on the context menu to delete a selected watch-expression.

(f)

Setting various events

By selecting [Access Break] or [Trace Output] on the context menu, it is possible to set various events in a selected watch-expression.

When an access-related break event is set, the icon of the watch-expression changes shape. (An event mark for break events is displayed additionally below the icon of the watch-expression.) If the event you set is a trace event, there are no changes to the mark of the watch-expression.

When an event is set, detail information on the set event is reflected in the Events panel.

However, events can be set only when the watch-expression for which you're going to set an event is a global variable, a static variable inside a function, a static variable inside a file, or an I/O register.

For details on how to set an event, see the sections listed below.

(g)

Jumping to a memory definition address

Selecting [Jump to Memory] on the context menu opens the Memory panel (Memory1), with the caret on it moved to the address where a selected watch-expression is defined. (If the Memory panel (Memory1) is already open, CS+ jumps to it directly.)

However, if multiple watch-expressions are selected at the same time or an I/O register or CPU register is selected, this operation has no effect.

(h)

Zoom in or out on a view

To zoom in and out of the Watch panel view, change the zoom ratio by using the drop-down list on the toolbar of the Main window while the focus is placed in the Watch panel.

You can also change the zoom ratio by using the [Ctrl] key + mouse-wheel combination.

-

Using the [Ctrl] key + mouse-wheel forward will zoom into the view, making the contents larger and easier to see (max. 300%).

-

Using the [Ctrl] key + mouse-wheel backward will zoom out of the view, making the contents smaller (min. 50%).

 

If the panel is closed after the zoom ratio is changed, the changed zoom ratio is retained (next time, the panel will open at the changed zoom ratio).

(2)

[Symbol] area

Symbols that have been registered as watch-expressions are displayed.

The display of the [Symbol] area is switched by selecting [Displays symbol column] from the context menu or toolbar.

When watch-expressions have a specified scope, the [Symbol] area is displayed without specifying the scopes of watch-expressions.

Example

var for prog$file#func#var

When arrays, pointer-type variables, and structures, unions, or classes of the watch-expression are expanded, the [Symbol] area displays watch-expressions including the name of the parent node.

Example

sobj.mem for the mem member expanded from the sobj structure object

(3)

[Value] area

This area displays or changes the value of a registered watch-expression.

Note that if the watch-expression is a function pointer, a function name is displayed.

The display notation (numeral representation) and encoding can be selected using a toolbar button or from the content menu. Also, it is possible to select a display form that always adds hexadecimal equivalents to the ordinary display.

Note that the default display form is automatically determined depending on the type of watch-expression, as follows:

Table A.11

Display Form of Watch-expressions (Default)

Type of watch-expression

Display form

char, signed char, unsigned char

Hexadecimal value added in "( )" following ASCII character

short, signed short, short int, signed short int, int, signed, signed int, long, signed long, long int, signed long int

Remark 1.

The I/O registers that may get the microcontroller operated unintentionally by a read operation are protected against reads, so that they are not loaded with values. To load the contents of the I/O registers protected against reads, select [Force Read Value] on context menu.

Remark 2.

Watch-expressions have their values acquired in the order they are registered.
Therefore, if two or more of the same I/O register are registered, their displayed values may not always the same, because their values are acquired with different timing.

Remark 3.

If hexadecimal equivalents are added, the value in specified notation and its hexadecimal equivalent are read out separately.
Therefore, the value in specified notation and its hexadecimal equivalent may not always agree, because they are acquired with different timing.

 

This area has the following features:

(a)

Realtime display update function

By using the realtime display update function, it is possible to display or change the value of a registered watch-expression, not only when the program is halted, but also when it is under execution.

For details about the realtime display update function, see "2.11.1.4 Displaying and changing memory contents during program execution."

(b)

Changing the value of a watch-expression

To change the value of a watch-expression, select the value of the subject watch-expression and click on it again. Then enter a new value directly from the keyboard. (Pressing the [Esc] key cancels the edit mode.)

When you've finished editing the value of a watch-expression, press the [Enter] key or move the focus to other than the edit area. The value you've changed is written into the target memory.

For details on how to change the value of a watch-expression, see "2.11.6.6 Changing the contents of watch-expressions."

(c)

Saving the values of watch-expressions

By choosing [Save Watch Data As...] from the [File] menu, it is possible to open the Save As dialog box and then save the entire content of this panel to a text file (*.txt) or CSV file (*.csv).

By selecting [Save Expanded Watch Data…] from the context menu, the Save As dialog box can be opened, and the selected contents of watch-expressions can be saved in a text file (*.txt) or CSV file (*.csv).

For details on how to save the values of watch-expressions, see "2.11.6.9 Saving the displayed contents of watch-expressions."

(4)

[Type (Byte Size)] area

This area displays the type information of watch-expressions in the form shown below.

Other than above

<Type of watch-expression as determined by C compilerNote 2> (<SizeNote 1>)

Note 1.

The sizes of watch-expressions are expressed in byte units.
For bit IORs and C bit fields, however, the sizes are displayed in bit units, with the "bit" notation added at the end of the value.

Note 2.

Watch-expressions are handled as having the type indicated here when they are compiled.
In the case of double/long double type, type name is output in accordance with "Precision of the double type and long double type" in the [CPU] Category on the [Common Options] Tab in the CC-RX Property panel. The type name and size are output in float type when "Handles in single precision" is selected and in double type when "Handles in double precision" is selected.

(5)

[Address] area

This area displays the address to which each watch-expression is mapped (always expressed in hexadecimal).

However, if the watch-expression is a single CPU register or not determinable, it is marked with "-" or "?," respectively.

Remark

If the watch-expression is an I/O register that is a bit register, a bit offset value is added to its displayed address, as shown below.

Example

For a bit register mapped to bit 4 at the address "0xFF40"
Displayed content: 0xFF40.4

(6)

[Memo] area

This area allows the user to enter a comment on a watch-expression or category, freely as desired.

The contents of comments entered in this area are held separately for each watch-expression and category, and are saved as user information on the project. Therefore, if one of these watch-expressions or categories is deleted, the content of its corresponding memo is also discarded.

Note that when an array, register or the like is expanded for display, you cannot enter a comment on any expanded element.

To edit a comment, double-click the item you want to edit. The selected item is placed in edit mode. (Pressing the [Esc] key cancels the edit mode.) A character string of up to 256 characters can be entered directly from the keyboard (new-line code ignored).

When you've finished editing a character string, press the [Enter] key or move the focus to other than the edit area to complete the character string editing.

[Toolbar]
