getDisplayChannelInfo
Return settings for Logic Analyzer display channel
Description
returns the settings for the display channel or channels, specified by the input
tag.channelInfo
= getDisplayChannelInfo(scope
,'DisplayChannelTag',tag
)
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
— Logic Analyzer object
dsp.LogicAnalyzer
object
The Logic Analyzer object from which you want to return display channel
settings, specified as a handle to the dsp.LogicAnalyzer
object.
tag
— Tag or tags identifying the display channel or channels about which to get information
character vector | string scalar | cell array of character vectors | string array
The tag or tags identifying the display channel or channels about which to get information.
Example: 'DisplayChannelTag','W5'
Example: 'DisplayChannelTag',{'W4','W5'}
Example: 'DisplayChannelTag',["W4","W5"]
Data Types: char
| string
Output Arguments
channelInfo
— Information about settings for the display channel or channels
struct
The channelInfo
struct contains the following fields:
Color
— Color of the waves.InputChannel
— Channel on the display that corresponds to the specified waves.Radix
— Radix for the waves.FontSize
— Font size for values in the waves. A value of0
indicates that the waves inheritFontSize
from the globalDisplayChannelFontSize
property.Name
— The name or label for the waves.Height
— Height of the wave. A value of0
indicates that the waves inheritHeight
from the globalDisplayChannelHeight
property.Tag
— Tag for the channel.
