Dll call help

[Champak]

Im trying to include this dll in my script and I'm having no luck. The dcdcOpenDevice function is returning 1 so the communication is good I believe, but the other two functions are returning 0. I believe I'm calling them correctly, however the vb example says I should be using "single" instead of "byte" on dcdcGetVin, but I dont see any reference to "single" in the help file.

Also, anytime the call to dcdcOpenDevice is made any of the msgbox or arraydisplay calls will cause the script to throw an error. But consolewrite is working just fine. Any help, thanks.

This is what I've tried.

#include <Array.au3>

$Open = DllCall("C:\Users\M35X\Desktop\release\DCDCUsbLib.dll", "Byte", "dcdcOpenDevice")
If @error Then MsgBox(0,0,@error)


$Connection = DllCall("C:\Users\M35X\Desktop\release\DCDCUsbLib.dll", "Byte", "dcdcGetConnected")
If @error Then MsgBox(0,0,@error)


$Voltage = DllCall("C:\Users\M35X\Desktop\release\DCDCUsbLib.dll", "Byte", "dcdcGetVin")
If @error Then MsgBox(0,0,@error)

ConsoleWrite("!! " & $Open[0] & @CRLF)
ConsoleWrite("!! " & $Connection[0] & @CRLF)
ConsoleWrite("!! " & $Voltage[0] & @CRLF)

;MsgBox(0,0,$Open[0])
;MsgBox(0,0,$Voltage[0])
;MsgBox(0,0,$Connection[0])

;_ArrayDisplay($Open,"Open")
;_ArrayDisplay($Connection,"connection")
;_ArrayDisplay($Voltage,"voltage")

 

This is VB coding

You are not using cdecl calling convention, see help file for dllcall

[Celtic88]

By default, AutoIt uses the 'stdcall' calling method. To use the 'cdecl' method place ':cdecl' after the return type.
DllCall("SQLite.dll", "int:cdecl", "sqlite3_open", "str", $sDatabase_Filename , "long*",

[Champak]

Thanks, I tried that, same issue.

Edited January 12, 2016 by Champak

[JohnOne]

Got link to documentation?

[Champak]

No documentation. Just the sdk with c#, c++, and vb examples. http://www.mini-box.com/DCDC-USB scroll down to downloads.

[RTFC]

The openDevice call fails because it expects you to parse an int parameter Timer (see Help doc for how to do this); and Single = Float, not Byte.

[Champak]

Based on your general understanding about these dllcalls, is that timer in the call meant to keep the device open for the other functions to communicate with the device and retrieve/set information?

I don't see anything in the help file about dllcall about timers or parsing, so is one of these attempts correct?
Like this?

$Open = DllCall("C:\Users\M35X\Desktop\release\DCDCUsbLib.dll", "Byte", "dcdcOpenDevice(1000)")

Or like this?

$Open = DllCall("C:\Users\M35X\Desktop\release\DCDCUsbLib.dll", "Byte", "dcdcOpenDevice", "int", 1000)

 

[JohnOne]

None of the are, do you remember "cdecl" calling convention?

Start using it in all of your attempts.

[trancexx]

JohnOne is right. If the documentation says cdecl the you have(!) to use :cdecl.
(However if the function has no parameters then calling convention is irrelevant)

$Open = DllCall($hDLL, "byte:cdecl", "dcdcOpenDevice", "dword", 1000)

 

[Champak]

Sorry, JohnOne I forgot to add it in this post, but I did put it in the script this morning and it didnt do anything....however, I didnt make the initial call to dcdcOpenDevice with the timer. 

@trancexx thanks, The functions, as far as i see do not have parameters, except the dcdcOpenDevice.

Edited January 12, 2016 by Champak

[RTFC]

@champak, I think you may have misunderstood my comment. That "Timer" variable is from your own VB script you posted. The first dllcall to open a device appears to expect an integer defining some timer, maybe a timeout before a "device not found" error is triggered or something (just guessing, I don't use that dll). So I think you'll need to include a predefined variable of type integer when you make that particular call. And trancexx is of course right; the calling convention defines in what order such parsed parameters are placed on the stack (for the dll to pop them off again), so if you use the wrong convention, misalignments and misattributions will happen if two or more parameters are parsed, and your call will then very likely fail. And if your first call to open a device has failed, then everything you try to do through the dll with that device thereafter will also fail, obviously.

From your responses I gather that you are not yet thoroughly familiar with dllcalls in general. There's a tutorial at https://www.autoitscript.com/forum/topic/93496-tutorial-on-dllcall-dllstructs/

Furthermore, if you're calling the same dll over and over, it's more efficient to open it once (receiving a handle) and then call it using its handle (of course, that means that you have to close it too when you're done).

[Champak]

Thats a good read. I was still getting nowhere with the adjustments, so I tried the open and close method and now I'm getting a return from dcdcGetConnected, but dcdcGetVin and every other "get" data function is not returning anything except 0. I know there is communication because when I disconnect the device dcdcOpenDevice returns 0 instead of 1.

This is my adjustment. Also, msgbox and array causing shuutdowns

#include <Array.au3>
$dll = DllOpen("C:\Users\M35X\Desktop\release\DCDCUsbLib.dll")

$Open = DllCall($dll, "Byte:cdecl", "dcdcOpenDevice", "dword", 1000)
If @error Then MsgBox(0,0,@error)

$Connection = DllCall($dll, "Byte:cdecl", "dcdcGetConnected")
If @error Then MsgBox(0,0,@error)

$Voltage = DllCall($dll, "float:cdecl", "dcdcGetVin")
If @error Then MsgBox(0,0,@error)

;$Close = DllCall($dll, "Byte:cdecl", "dcdcCloseDevice")
;If @error Then MsgBox(0,0,@error)

DllClose($dll)

ConsoleWrite("!! " & $Open[0] & @CRLF)
ConsoleWrite("!! " & $Connection[0] & @CRLF)
ConsoleWrite("!! " & $Voltage[0] & @CRLF)
;ConsoleWrite("!! " & $Close[0] & @CRLF)


;MsgBox(0,0,$Open[0])
;MsgBox(0,0,$Voltage[0])
;MsgBox(0,0,$Connection[0])

;_ArrayDisplay($Open,"Open")
;_ArrayDisplay($Connection,"connection")
;_ArrayDisplay($Voltage,"voltage")

Any other ideas?

[JohnOne]

Have you tried any other functions like dcdcGetVersionMajor etc?

[Champak]

Yes, all of them, and all return 0. When I start playing with and changing the return type, I get sequence of numbers, but none of which are what they should be...if that matters.

 

[JohnOne]

Can you humour me and change byte return type to int.

[JohnOne]

In the C++ code it appears to imply that dcdcGetConnected is of type bool...

Thanks JohnOne for pointing out that version, it helped me to fix my issue. It needs to sleep a bit after each call...not just the openDevice as it states here... even if the call has nothing to do with the next function. Thanks all for your help.

So I understand the thinking for future (even though it may seem obvious at this point), what made you look in this version as opposed to just relying on the vb version which is more closely related to autoit.

@J1 : I'm not clever with Dllcall and variables types, maybe you can confirm that : if I understand the helpfile, BYTE and BOOLEAN are both "an unsigned 8 bit integer", so it should work with both in the DllCall, no ?

There's a difference in size between BOOLEAN (8 bits, unaligned = 1 BYTE) and BOOL (32-bits, memory-aligned = 4 BYTES).
