#Requires -Version 7.1 <# .SYNOPSIS Read Customer code(16bit) and Data(8bit) on NEC Format from a [IRKit get-method data]. (https://getirkit.com/en/#toc_1) .INPUTS String. It should have a only pair of []. You can pipe objects from a IRKit get-method data. .OUTPUTS PSCustomObject. Properties are CustomerCode(16bits string) and Data(8bits string). .EXAMPLE PS> curl -s -i "http://192.168.0.1/messages" -H "X-Requested-With: curl" | Read-CustomerCodeAndData_fromNECformated_IRKitGetData .EXAMPLE PS> Read-CustomerCodeAndData_fromNECformated_IRKitGetData "[17984,8992,1124,1124,..,3372,1124]" #> function global:Read-CustomerCodeAndData_fromNECformated_IRKitGetData { [CmdletBinding()] [OutputType([PSCustomObject])] Param ( [Parameter(ValueFromPipeline = $True)]$st ) Begin { Get-ChildItem (Get-Item $PSScriptRoot).parent -Include "*.ps1" -Recurse | Where-Object { $_.Name -notmatch "\.Tests\." } | Where-Object FullName -Like "*\Private\*" | ForEach-Object { & $_.PSPath } [int]$T = 562 # modulation unit (μs) [int]$customerCodeFirstIndexPosition = 2 [int]$customerCodeLastIndexPosition = 33 [int]$dataFirstIndexPosition = 34 [int]$revdataLastIndexPosition = 65 [int]$minimunRequiedLength = $revdataLastIndexPosition $result = [PSCustomObject]@{ CustomerCode = "" Data = "" } } Process { $regex = '\[.+\]' if (Select-string -InputObject $st -Pattern $regex -Quiet) { $IRKitData = Select-string -InputObject $st -Pattern $regex | ForEach-Object { $_.Matches } | ForEach-Object { $_.Value } # transfer IRKit count data to T(T: modulation unit) based data. # 1 IRKit count is 2MHz(= 2*10^6 /s).
