ACCES USB-IDIO-16 DLL or Low-Level control

7 posts in this topic

This I/O board is pretty sweet and seems to have some great capabilities if they can be accessed in a more "OEM" manner than I realized when I bought it.

Details can be found at:  http://accesio.com/go.cgi?p=/104/104-idio-16.html  (picked it up on EBay for $45.

I am planning to use my new Acces USB-IDIO-16 to control the switching of my HO model train hump yard layout. I am wanting to use the USB interfacing of this card to;
1) resd a RFID reader (with data going into Excel 2013 at the moment (to determine the cars making up the train)
2) use the IDIO-16 to control the switches and

3) monitor the photoeyes.

ASSEC's reply for help:

The easiest way to control a single relay from any language or environment is "DIO_Write1()".  If you only have one USB device you're connected to, just use the "diOnly" constant (-3, or 0xFFFFFFFD) for the "Device Index" parameter.  This leaves the call looking like this:

Status = DIO_Write1(&hFFFFFFFD, relayNumber0to15, TrueOrFalse);

Which translated to:(I cut out some details, but you get the idea (that I need some guidance).

Sub IOCard()
Public Declare Function DIO_Write1 Lib "AIOUSB" Alias "VBDIO_Write1" (ByVal DeviceIndex As Long, ByVal BitIndex As Long, ByVal Data As Boolean) As Long

Status = DIO_Write1(&HFFFFFFFD, 0, True)

This avenue isn't going too well, various Windows errors, so after more reading, I thought to maybe try the low-lo-level control functionality ASEC supports. After asking them about this, I got the flowing reply today:

Windows doesn't provide any method of making a "USB control transfer", which is necessary to use the low level interface.

Well, in my blissful ignorance, I am thinking that Assec might just be the ticket to the fast track to success but I'm still digging and have decided to share my thoughts with all of you here on this sight.

So, any thoughts (or questions for clarity)?

questions for clarity?

Is there actually an AutoIt question in all of that? :huh:

Yes, My questions are these;

1) Does anyone out there have any experience with this board and can you help me to get it to work?

2) Can AutoIT be used to communicate with a USB port at a Low-Level?

Thanks for asking,

Brad

I think that device has a library that can be used with autoit.

I see the manual and says this in C

UInt32 GetDeviceByEEPROMByte(Byte Data);
 
so with autoit you could do something like this:
 
DllCall("yourlibary","UINT","GetDeviceByEEPROMByte","BYTE",$Data)

I think I'm wrong in my above answer. so I still think you can use autoit. Look Chapter 5 here

as I can read. when you install the sdk/driver you should have some examples(vb6,C,delphi,vbet,C#)

Just traslate it to autoit.

I've read bad. Autoit can not work in low level. so instead use the win32 library.

Thanks Danyfirex,

I'll dig into this more tonight. I got another reply from the manufacturer as follows:

I think it might be straightforward if you use the .NET wrapper dll we created a while back, AIOUSBNet.dll, instead of using AIOUSB.dll directly.

I'll try to put all this together "with a little help from my friends" and see what happens .....

Cheers & thx again for the help
