Measuring Current Consumption panel [E2]

This panel is central to the functionality of the solution for measuring current consumption.

See "2.19 Measuring Current Consumption [E2]" for details on the solution for measuring current consumption.

Caution 1.

Measuring current consumption is only available for the RX100 and RX200 Series.

Caution 2.

There will be some error in the results of measurement. For the specifications of the measurement of current consumption, e.g. the maximum current consumption, the maximum time over which measurement is possible, the resolution of measurements of current consumption, etc., refer to the E2 Emulator User's Manual.

[How to open]

-	From the [Debug] menu, select [Debug Solutions] >> [Measuring Current Consumption].

-	On the Solution List panel, click the [Go] button of Measuring Current Consumption.

[Description of each area]

(1)	Warning display area

This area shows warning messages if there are inconsistencies between the conditions for measurement of current consumption and the conditions to be set before the debug tool is connected.

This area is hidden when there is no warning to be reported.

(2)	Graph display area

This area shows the measured results for current consumption with the current represented by the y axis and time by the x axis of the graph.

This area also has the following lines which can be dragged.

Supplementary Line	Description
Cursor	Red vertical line
Marker A, Marker B	Green vertical line
Supplementary lines for searching	Orange horizontal line

When a cursor or marker is dragged, information in the information display area is updated accordingly.

The supplementary lines for searching are used to simply specify the threshold current which is the basis of the search.

Remark

While current consumption is being measured, the display of data is cleared and the cursor and markers cannot be dragged.

(3)	Information display area

This area displays particular values from the graph of the measured data that is displayed in the graph area.

(a)	[Average current]

The average of the values for current between markers A and B is displayed.

When there are no markers, blank space is displayed.

(b)	[Maximum current]

The maximum of the values for current between markers A and B is displayed.

When there are no markers, blank space is displayed.

(c)

[Current]

The values for current at the position of the cursor is displayed.

When the cursor is not displayed, this item becomes blank.

(d)

[Time]

The time at the position of the cursor is displayed.

When the cursor is not displayed, this item becomes blank.

(e)	[Marker A]

The time at the position of marker A is displayed.

When marker A is not displayed, this item becomes blank.

(f)	[Marker B]

The time at the position of marker B is displayed.

When marker B is not displayed, this item becomes blank.

(g)

[B - A]

The time between markers A and B is displayed.

When markers are not displayed, this item becomes blank.

(4)	Monitor point list display area

This area displays a list of monitoring points that have been set and is used to specify the settings for building and downloading when monitor points are set.

(a)	[Hold the build options for monitor point specified when measuring]

When building proceeds with the function for automatically inserting nop instructions for monitoring points, the options for use in building are reflected in the properties of the build tool.

Caution

This check box is only effective when the compiler for the current active project is CC-RX V2.08.00 or later.

(b)	[Monitor point list]

A list of monitoring points that are currently set is displayed.

When the measured results are displayed in the graph display area and a cell is double-clicked with each line of the list selected, the cursor in the graph display area is moved to the position of the monitoring point that is indicated by that line.

A selected monitoring point can be deleted by pressing the [Delete] key.

The following describes the individual components.

<1>

Check box

Monitoring points for which the check boxes are selected are valid in the measurement of current consumption.

<2>

Cursor

Displays the cursor in the graph display area at the position of the monitoring point on the given line.

When the cursor is selected for a point, the background color of the cell changes to red.

<3>

Count

Displays how many times the monitoring point on the given line has been crossed during measurement.

<4>

Location

Displays the position of the monitoring point on the given line in the format "file-name#line-number (address)".

Example

main.c#16(0xFFF0E)

Caution

Addresses are only displayed when they have already been determined during measurement.

<5>	Line Color

In the graph display area, the color of the vertical line is displayed at the position corresponding to the monitoring point on the given line.

[Toolbar]

		Executes the program and starts measurement of current consumption. When V2.08.00 or later of the CC-RX compiler is selected for the active project, rebuilding and downloading are performed to insert nop instructions at the positions corresponding to monitoring points in the source file registered in the active project.
		Executes the program and starts measurement of current consumption. Rebuilding and downloading are not performed to insert nop instructions at the positions corresponding to monitoring points. Note that this button appears when V2.08.00 or later of the CC-RX compiler is selected for the active project.
		Has the same functionality as the same button on the Debug toolbar in the Main window.
		Opens the Current Consumption Measurement Condition Setting dialog box [E2] to set measurement conditions.
		Opens the Current Consumption Measurement Trigger Condition Setting dialog box [E2], which is used to set trigger conditions for measurement.
		Moves marker A in the graph display area to the corresponding position.
		Moves marker B in the graph display area to the corresponding position.
		Moves the cursor in the graph display area to the corresponding position.
		Switches between showing and hiding the cursor, marker A, marker B, and the supplementary lines for searching in the graph display area.
		Searches for the first position that matches the condition set with the supplementary lines for searching and the search mode. When the position is found, the cursor in the graph display area is moved to that position.
		Searches for the first position before the cursor position that matches the condition set with the supplementary lines for searching and the search mode. When the position is found, the cursor in the graph display area is moved to that position.
