      Hi All,
      I didn't know where to put this; my apologies if this is the wrong location.
      When you plug a Samsung mobile device (phone, tablet, etc.) into the USB of a Windows PC, you can right-click the device in My Computer and select Properties. Here, it will show you the correct serial number of the device. Clearly Windows doesn't use adb to get the SN so I'm stuck at how to get the SN without adb and where the device doesn't have a drive letter assigned to it.
      When I last picked this up, I tried seemingly everything I could from wmi(?) and winmgmts(?) but either it's hidden cloak-and-dagger style or I can't see the forest for the trees...
      Does anyone know what API Windows uses when getting the serial number of a device Windows calls a Portable Media Player?

      Hi
      here's another UDF for the serial port. It is very similar to CommAPI using kernel32.dll, but all code is packed into a single file without any dependencies, not even using WinAPI.au3. It differs from existing UDF that it doesn't allow a timeout when reading, instead it always returns immediately, either with the requested amount ob bytes read or with a failure status. And of course there is a function provided to query the amount of available bytes in the receive buffer. The reason behind this design decision: You can do 1000 other things in the main loop while checking from time to time if enough data bytes arrived. There's no point to block the program waiting for the serial port.
      It is currently a work-in-progress, as I didn't test all functions yet. The code was developed and tested on Windows 7 64 bit.  The ComUDF-Tests.au3 shows some tests and basic usage of the UDF. Maybe there's no reason to use this UDF, given the existence of the others UDFs, but I did it to get to know DllCall better - I use structs no only to pass but also to get data back (I don't use the array returned by DllCall to read that data, unless required). You're welcome to test it on older and newer Windows versions.
      Here's a list of the implemented functions:
      ; _ComListPorts ; _ComOpenPort ; _ComSetTimeouts ; _ComClosePort ; ; _ComSetBreak ; _ComClearBreak ; _ComGetInputcount ; _ComGetOutputcount ; _ComClearOutputBuffer ; _ComClearInputBuffer ; ; _ComSendByte ; _ComReadByte ; _ComSendBinary ; _ComReadBinary ; ; _ComSendChar ; _ComReadChar ; _ComSendCharArray ; _ComReadCharArray ; _ComSendString ; _ComReadString ; ; __ComClearCommError ; __PurgeComm Maze

      Hi 
      I am trying to open a dll using DLLOpen, however everytime i try to do so the function fails and returns -1 result. 
      I have the dll in the same folder as the auto it script. 
      Local $hDLL = DllOpen("C:\Users\310255155\Downloads\COMMGvv2\commg.dll") DllCall($hDLL, "int", "MessageBox", "hwnd", 0, "str", "Some text", "str", "Some title", "int", 0) DllClose($hDLL) MsgBox(0,'result',$hDLL)

      So I'm trying to send a string of data to Arduino using CommMG UDF. It seems that Arduino is not receiving it. I used Device Monitoring Studio and it shows that the data is sent fine and looks exactly the same as if I sent it from Arduino Serial Monitor. Is CommMG compatible with USB?
      Global $CMPort = 9 Global $CmBoBaud = 9600 Global $sportSetError = '' Global $CmboDataBits = 8 Global $CmBoParity = "none" Global $CmBoStop = 1 Global $setflow = 2 _CommSetPort($CMPort, $sportSetError, $CmBoBaud, $CmboDataBits, $CmBoParity, $CmBoStop, $setflow) If @error Then MsgBox(16,"Error!","Can't connect to Arduino on port - "&$CMPort) Exit EndIf _CommSetRTS(0) _CommSetDTR(0) _CommSendString("x" & 128 & "y" & 256 & "e", 1)

      I was just working on a project that involved decoding a stream of binary data from a serial port in AutoIt.  It took me a few hours to figure out how to process the data efficiently in AutoIt and I did not find any helpful examples on how to do so, so I thought I would share my core example and maybe save someone else some time.  There may be a more efficient way to do this, but this works well for me.
       
      #cs Author: ToasterKing This is an example of a way to parse streaming binary data that follows a strict format with a header and footer. In this example, each frame is 5 bytes with a 2-byte header of 0xD5AA and a 1-byte footer of 0xAD. The _BinaryParse() function accumulates incoming data in a buffer. Once a footer is found, it searches backward for the header, and if it is in the right position, it extracts the remaining 2 bytes in the middle, then moves on to looking for the next frame. #ce ; The data source might be something asynchronous like serial or TCP, but since this is just an example, I'm just putting the data in a variable. Local $fSomeData $fSomeData = Binary("0xD5AA24B1") ; Binary data constituting almost a complete frame. _BinaryParse($fSomeData) ; Call the function with the received data. It isn't a complete frame, so it is just stored in the buffer until more data is received. $fSomeData = Binary("0xAD62D5AA92E7AD") ; Remainder of the previous frame, one garbage byte (0x62) which should be skipped, and a complete additional frame. _BinaryParse($fSomeData) ; The function should be able to parse both frames now. Func _BinaryParse($fNewData) Local Static $fBinaryReceived = Binary("") ; Buffer for received data ConsoleWrite("Hey, the function is called!" & @CRLF) ; Add new data to the buffer. ; This ridiculous monstrosity is the only way I could find to append binary data to binary data in AutoIt. It must be converted to strings first. ; Both, one, or no substrings will begin with "0x" depending on whether they contained binary data. To be converted back to binary properly, only one instance ; of "0x" must exist at the beginning of the string. $fBinaryReceived = Binary("0x" & StringReplace(String($fBinaryReceived) & String($fNewData),"0x","")) ConsoleWrite("Data in the buffer: " & String($fBinaryReceived) & @CRLF) Local $iLength = BinaryLen($fBinaryReceived) ; Count the bytes in the data If $iLength > 0 Then Local $fBinaryReceivedTemp = $fBinaryReceived ; Create temporary copy to work on Local $fByte1,$fByte2 For $i = 1 To $iLength If BinaryMid($fBinaryReceivedTemp,$i,1) = 0xAD Then ; If the 1-byte footer found ConsoleWrite("Footer found at end of " & $i & " of " & $iLength & " bytes!" & @CRLF) If BinaryMid($fBinaryReceivedTemp,$i - 4,1) = 0xD5 And BinaryMid($fBinaryReceivedTemp,$i - 3,1) = 0xAA Then ; and the 2-byte header is found 4 bytes before that ConsoleWrite("Header found before the footer!" & @CRLF) $fByte1 = BinaryMid($fBinaryReceivedTemp,$i - 2,1) ; Get 1st byte in the body (between header and footer) $fByte2 = BinaryMid($fBinaryReceivedTemp,$i - 1,1) ; Get 2nd byte in the body (between header and footer) ConsoleWrite("Here is the critical data: " & String($fByte1) & " " & String($fByte2) & @CRLF) ; Just display the 2 bytes for demonstration purposes. Normally, you'd do something more useful with it here. EndIf $fBinaryReceived = BinaryMid($fBinaryReceivedTemp,$i + 1) ; Truncate the original data to remove all of the bytes just processed, then continue processing $fBinaryReceivedTemp EndIf Next EndIf EndFunc
