addWave
Add wave to Logic Analyzer
Description
Examples
Manipulate Logic Analyzer Programmatically
Use functions to construct and manipulate a dsp.LogicAnalyzer System object.
Display Waves on Logic Analyzer scope.
scope = dsp.LogicAnalyzer('NumInputPorts',2); stop = 30; for count = 1:stop sinValVec = sin(count/stop*2*pi); cosValVec = cos(count/stop*2*pi); cosValVecOffset = cos((count+10)/stop*2*pi); scope([count (count-(stop/2))],[sinValVec cosValVec cosValVecOffset]) end
Reorganize Display
hide(scope) digitalDividerTag = addDivider(scope,'Name','Digital','Height',20); analogDividerTag = addDivider(scope,'Name','Analog','Height',40); tags = getDisplayChannelTags(scope); modifyDisplayChannel(scope,tags{1},'InputChannel',1,... 'Name','Ramp Digital','Height',40); modifyDisplayChannel(scope,tags{2},'InputChannel',2,... 'Name','Waves Analog','Format','Analog','Height',80); moveDisplayChannel(scope,digitalDividerTag,'DisplayChannel',1) moveDisplayChannel(scope,tags{2},'DisplayChannel',length(tags)) show(scope)
Duplicate Wave and Check Information
hide(scope) addWave(scope,'InputChannel',2,'Name','Waves Digital','Format','Digital',... 'Height',30,'DisplayChannel',3); show(scope)
Remove Dividers
hide(scope) deleteDisplayChannel(scope,digitalDividerTag) deleteDisplayChannel(scope,analogDividerTag) show(scope)
Clear variables
clear analogDividerTag cosValVec cosValVecOffset count digitalDividerTag duplicateWave scope sinValVec stop tags
Input Arguments
scope
— The Logic Analyzer object to which you want to add a wave
dsp.LogicAnalyzer object
Example: 'addWave(scope)'
adds a wave with the default characteristics.
Name-Value Arguments
Specify optional pairs of arguments as
Name1=Value1,...,NameN=ValueN
, where Name
is
the argument name and Value
is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Before R2021a, use commas to separate each name and value, and enclose
Name
in quotes.
Example: 'InputChannel',2,'Color','Blue'
specifies that a wave should be added to input channel 1 and
colored blue.
Color
— Color of the wave
'Default'
(default) | character vector | three element numeric vector | string scalar
Color of the wave, specified as an [R G B]
value or one of the following:
'Black'
'Blue'
'Cyan'
'Default'
'Green'
'Magenta'
'Red'
'White'
'Yellow'
When you choose 'Default'
, the value of the DisplayChannelColor
property in the Logic Analyzer is used.
Example: 'Color','Blue'
Example: 'Color',[0,0,1]
Data Types: char
| string
| double
| single
| uint8
| uint16
| uint32
| uint64
| int8
| int16
| int32
| int64
DisplayChannel
— Channel on the display that shows this wave
NumInputPorts
(default) | scalar numeric value in the range (1,NumInputPorts
)
Specify as a scalar numeric value the display channel that shows this wave. By default, the wave is added to the end of the display.
Example: 'DisplayChannel',2
Data Types: double
| single
| uint8
| uint16
| uint32
| uint64
| int8
| int16
| int32
| int64
FontSize
— Font size for values in the wave
0
(default) | scalar nonnegative integer
Specify as a scalar nonnegative integer the font size in points. When you choose 0, the value of the
DisplayChannelFontSize
property in the Logic Analyzer is used.
Example: 'FontSize',8
Data Types: double
Format
— Display format for the wave
'Default'
(default) | 'Analog'
| 'Digital'
When you choose 'Default'
, the value of the DisplayChannelFormat
property in the Logic Analyzer is used.
Example: 'Format','Digital'
Data Types: char
| string
Height
— Height of the wave
0
(default) | scalar integer
Specify as a scalar integer the height of the wave in the display in units of 16 pixels. When you choose 0,
the value of the DisplayChannelHeight
property in the Logic Analyzer is used.
Example: 'Height',2
Data Types: double
InputChannel
— Input channel that corresponds to this wave
1
(default) | scalar integer in the range (1,NumInputPorts
)
This property specifies the input channel whose data is used for this wave. By default, it will connect the first input to this wave.
Example: 'InputChannel',2
Data Types: double
| single
| uint8
| uint16
| uint32
| uint64
| int8
| int16
| int32
| int64
Name
— Name or label for the wave
''
(default) | character vector | string scalar
Specify the name that you would like to set for the new wave.
Example: 'Name','MyWave'
Data Types: char
| string
Radix
— Radix for the wave
'Default'
(default) | 'Binary'
| 'Hexadecimal'
| 'Octal'
| 'Signed decimal'
| 'Unsigned decimal'
When the input signals are of class double, single, or logical, you should not set this property. When you
choose 'Default'
, the value of the DisplayChannelRadix
property in the
Logic Analyzer is used.
Data Types: char
| string
Output Arguments
waveTag
— tag for new wave
random character vector
A tag for the newly added wave. Use the tag name to modify and delete the wave.
