Arduino通过PowerShell脚本与PC进行通信

最近我编写了一个项目，目的是为了控制使用Arduino的红外遥控器和IR遥控器以及PC上运行的PowerScript来通过串口接收来自Arduino的信息。Arduino通过PowerShell脚本与PC进行通信

问题是，我如何编写PowerShell脚本才能在从Arduino获得一些输入时执行某些操作。因为现在我在PowerShell脚本中有一个延迟循环，每次执行代码时，它都会读取并检查它是否从Arduino获得了一些输入。但是我怎么能不等待，但只有当Arduino发送了一些东西时才触发PowerShell脚本？

这里是我的PowerShell脚本：

$console = $host.UI.RawUI 
$console.BackgroundColor = "darkgreen" 
$console.ForegroundColor = "black" 
$size = $console.WindowSize 
$size.Width = 15 
$size.Height = 2 
$console.WindowSize = $size 
$buffer = $console.BufferSize 
$buffer.Width = 15 
$buffer.Height = 2 
$console.BufferSize = $buffer 

Write-Host "PC Media Remote" 

function IRinputText { 
    Param([string]$serialread,[string]$combo,[string]$key) 
    Process{If ($IRbuffer -like ("*"+$serialread)) {IRbufferReset;$wshell.SendKeys($combo+"{"+$key+"}")}} 
    } 
function IRinputHEX { 
    Param([string]$serialread,[string]$key) 
    Process{If ($IRbuffer -like ("*"+$serialread)) {IRbufferReset;$wshell.SendKeys([char]+$key)}} 
    } 
function IRbufferReset { 
    $Script:IRbuffer="" 
    $Script:IRbuffer= $Script:IRbuffer.PadLeft(15,'0') 
    } 

IRbufferReset 

$port= new-Object System.IO.Ports.SerialPort COM4,9600,None,8,one 
$wshell = New-Object -ComObject wscript.shell; 
$port.open() 
while($true) 
{ 
    $inputvar= $port.ReadExisting() -replace "`n","" -replace "`r","" 
    If(($inputvar -ne "")){ 
     $IRbuffer= If($IRbuffer.Length -ge $inputvar.Length){$IRbuffer.Substring($inputvar.Length) } 
     $IRbuffer= $IRbuffer + $inputvar 
     } 
    If($IRbuffer.Length -gt 15){$IRbuffer= $IRbuffer.Substring($IRbuffer.Length - 15);} 
    IRinputText -serialread "CH+" -combo "^" -key "UP" 
    IRinputText -serialread "CH-" -combo "^" -key "DOWN" 
    IRinputText -serialread "100+" -combo "^" -key "LEFT" 
    IRinputText -serialread "200+" -combo "^" -key "RIGHT" 
    IRinputText -serialread "CH" -key "f" 
    IRinputHEX -serialread "VOL+" -key "0xAF" 
    IRinputHEX -serialread "VOL-" -key "0xAE" 
    IRinputHEX -serialread "PLAY/PAUSE" -key "0xB3" 
    IRinputHEX -serialread "PREV" -key "0xB1" 
    IRinputHEX -serialread "NEXT" -key "0xB0" 
    IRinputHEX -serialread "EQ" -key "0xAD" 
    If ($IRbuffer -like ("*1532")) {IRbufferReset;Stop-Computer} 

    Start-Sleep -m 20 
}

您可以subscripe PowerShell来这是由次曝光的DataReceived事件检索处理e SerialPort类。（这就是我用Arduinos来做的） – bluuf

@bluuf你能详细介绍一下吗？我是PowerShell的绝对初学者。谢谢！ – raulx222

如果使用Firmata协议上Arduino的话，我已经工作示例PowerShell事件驱动接口的GPIO设备与Arduino的通信通过使用一个.net库调用实体。 Arduino的（https://github.com/SolidSoils/Arduino）

add-type -path '.\Documents\WindowsPowerShell\Solid.Arduino.dll' 
$connection = New-Object Solid.Arduino.SerialConnection("COM4",[Solid.Arduino.SerialBaudRate]::Bps_57600) 
$session = New-Object Solid.Arduino.ArduinoSession($connection, 2000) 
$session.SetDigitalPinMode(4,[Solid.Arduino.Firmata.PinMode]::DigitalInput) 
# 
# Define the function that is called when a digitial pin event happens 
# 
function inputevent($event){ 
#Write-Host "Something happened on port $($event.value.port) Type $($event.value.pins)" 
if($event.value.pins -band 4) #using binary AND incase multiple inputs are activated 
{ 
    # put code here to switch ATEM Aux or VideoHub routing 
    Write-host "Cam 1 preview selected" 
} 
} 
# 
# set up the event to montor digital pin state change 
# 
$session.SetDigitalReportMode(0,$true) #enable events for pins on port 0 
Unregister-Event eventBitChange -ErrorAction SilentlyContinue #incase we are re-running the script 
$ArduinoEvent = Register-ObjectEvent -InputObject $session -EventName DigitalStateReceived -SourceIdentifier eventBitChange -Action {inputevent($eventArgs)}
