Architerion Posted June 10, 2015 Share Posted June 10, 2015 HowdyI am writing a multichannel batching sequence for a usb relay controller using the FTD chip (denkovi 16 channel board). I couldnt actually get a working example using the FTD udf...port opens etc but nothing happening. I would be happy to pay someone for a working example though. However I ended up doing a quick example just writing to the serial port using the _Comm udf and it works fine eg the following #include <CommMG.au3>Global $Port=12, $Baud=9600, $Databits=8, $Parity="none", $Stopbits=1, $Flow=0, $RTS=0, $DTR=0, $Received$Result = _CommSetport($Port, $Received, $Baud, $Databits, $Parity, $Stopbits, $Flow, $RTS, $DTR)If $Result <> 1 Then MsgBox($MB_SYSTEMMODAL,"CRITICAL WARNING!", "Could not set USB port connection...is unit plugged in?")$Result = _CommSendString("06+//",0)Sleep(1000)$Result = _CommSendString("06-//",0) When I use it in a loop; it doesnt return though? Local $hDLL = DllOpen("user32.dll")Global $Port=12, $Baud=9600, $Databits=8, $Parity="none", $Stopbits=1, $Flow=0, $RTS=0, $DTR=0, $Received$Result = _CommSetport($Port, $Received, $Baud, $Databits, $Parity, $Stopbits, $Flow, $RTS, $DTR)While 1 Select Case _IsPressed("7B", $hDLL) While _IsPressed("7B", $hDLL) Sleep(50) WEnd ; Wait until key is released. ConsoleWrite("Pressed") TestFunc() EndSelect Sleep(50)WEnd Func TestFunc() $Result = _CommSendString("06+//",0) Sleep(500) $Result = _CommSendString("06-//",0)ReturnAm I missing something (Obviously hehe)?Help!

SadBunny Posted June 10, 2015 Share Posted June 10, 2015 What do you mean by "it doesn't return"? I assume you mean the TestFunc() doesn't finish. Does it print the "Pressed"? Have you tried ConsoleWriting those $Result vars in the TestFunc(), to see where it hangs? And ConsoleWriting "Done with function" under the call to TestFunc()?Assuming you included Misc.au3 for the _IsPressed, and ended that function with endfunc, that bit of code there should work.

The relays turn on and off but the program itself no longer responds to key presses and I have to hard break the execution. It is as if _Comm runs off with the thread and never comes back.

SadBunny Posted June 11, 2015 Share Posted June 11, 2015 (edited) All fine, but we still don't know where exactly it hangs. It enters the function and executes the two commands, apparently, but does it return from that second command? If it does, the problem is somewhere in the code you didn't post. If it doesn't, the problem is somewhere in the udf. Kind of hard to troubleshoot with non-functional code with too little logging...Try main loop and func like this:While 1 Select Case _IsPressed("7B", $hDLL) While _IsPressed("7B", $hDLL) Sleep(50) WEnd ; Wait until key is released. ConsoleWrite("Pressed") TestFunc() ConsoleWrite("Returned from TestFunc()" & @CRLF) EndSelect Sleep(50) WEnd Func TestFunc() $Result = _CommSendString("06+//", 0) ConsoleWrite("Result of first call: " & $Result & @CRLF) Sleep(500) $Result = _CommSendString("06-//", 0) ConsoleWrite("Result of second call: " & $Result & @CRLF) Return EndFunc ;==>TestFuncIt should write "Pressed", then the two results (for this purpose we don't care what those results actually are as long as they get printed), and then "Returned". But it will not, because it gets stuck somewhere. This will tell you where.Note that you could also use HotKeySet() instead of the _IsPressed thing.

Architerion Posted June 11, 2015 Author Share Posted June 11, 2015 Cheers. Will give that a go in the morning...just about bedtime here in ol Sydney town.Im sorry for the incomplete coding...was tired, actually burnt out when I posted. Ill just get this simple loop going first and come back with the rest of the code as its resolved. It actually uses a 3 deep array to run some parametric timers...Thanks so much for your time/helpM Link to comment Share on other sites More sharing options...
SadBunny Posted June 11, 2015 Share Posted June 11, 2015 (edited) No problem worries (right? Am I an Ozzie yet? ) Dutch boy living in Sydney here. You sure have an early bedtime By the way, try writing a short reproducer that a) actually works and b) actually reproduces the problem. It often helps laying the problem bare.

Architerion Posted June 11, 2015 Author Share Posted June 11, 2015 Hehe..Kein Problem...yep you are officially an Ozzie...I stand corrected ;-)Im a German background boy that has to get up real early...and after wind down tasks...its not so early a bedtime.Advice well taken...will do and see how it goes. bis dann!

Architerion Posted June 15, 2015 Author Share Posted June 15, 2015 Ok...here is the actual example (debug) code. Runs fine with debugs printed correctly until I uncomment the commport open stuff. then it only gets to Stage: PreLoop #include <Misc.au3>#include <MsgBoxConstants.au3>#include <Date.au3>#include <GUIConstantsEx.au3>#include <GuiButton.au3>#include <WindowsConstants.au3>#include <Timers.au3>#include <FTD2XX_UDF.au3>#include "OnAutoItErrorRegister.au3"#include <Sound.au3>#include <CommMG.au3>Local $hDLL = DllOpen("user32.dll")Global $Port=13, $Baud=9600, $Databits=8, $Parity="none", $Stopbits=1, $Flow=0, $RTS=0, $DTR=0Global $Received, $Result, $PortList[100];~ $Result = _CommSetport($Port, $Received, $Baud, $Databits, $Parity, $Stopbits, $Flow, $RTS, $DTR);~ ConsoleWrite($Result);~ $Result = _CommSendString("00", 0)ConsoleWrite(@CR & "Stage: Pre Loop");~ HotKeySet("{F12}", "TestFunc")While 1 Select Case _IsPressed("7B", $hDLL) ConsoleWrite(@CR & "Stage: While Loop") While _IsPressed("7B", $hDLL) Sleep(50) WEnd ; Wait until key is released. ConsoleWrite(@CR & "F12 Pressed") TestFunc() ConsoleWrite(@CR & "Returned from TestFunc()" & @CRLF) EndSelect Sleep(50)WEndFunc TestFunc() $Result = _CommSendString("09", 0) ConsoleWrite(@CR & "Result of first call: " & $Result & @CRLF) Sleep(500) $Result = _CommSendString("00", 0) ConsoleWrite(@CR & "Result of second call: " & $Result & @CRLF) ReturnEndFunc ;==>TestFunc Link to comment Share on other sites More sharing options...
SadBunny Posted June 15, 2015 Share Posted June 15, 2015 So it says "Pre Loop" but it doesn't say "While Loop" when you press the key? Or are you using the hotkeyset instead? If so, disable the Case _IsPressed("7B") and add a line to the beginning of the TestFunc to see if it even gets there.If it's starting to look like something goes wrong in the first _CommSendString(), you'll have to go into the UDF with the same kind of troubleshooting. Just keep tracing your call down the functions and see where it fails. Roses are FF0000, violets are 0000FF... All my base are belong to you.
