ADSmartIO wrapper class

This helper class wraps the ADSmartIO functions and exposes them in a class hierarchy providing a layer of object safety and the ability to validate parameters. The class constructor dynamically binds to the ADSmartIO library on the device.

I am running OS 4.10.19 on a BitsyX (the one with file viewers). Unfortunately, the wrapper class fails to load SMARTIO.dll. I looked for the dll in the Windows directory but could not find it. I was under the impression that SMARTIO.dll was part of the build. Does it live somewhere else or is it not included in the build? If it is not included in the build, how can I get it?

I should note, keybddr.dll does load. However, when I call ADSmartIO.SetBacklightState (FALSE) I get a data abort message and the system hangs. Here is the debug output.

Rev 2 Update

Dave,

Good catch. Rev 1 didn't have a GetProcAddress call for the BackLight functions. I've made the fixes in rev 2 as well as adding safety checks in all functions to ensure that only calls to successfully loaded functions can be made.

I would also like to know where SMARTIO.DLL is located (or installed from). I'm using a Bitsy Plus with CE.net 4.13 and don't have this dll in my windows directory.

Some ADS platfroms have SMARTIO.DLL, some have KEYBDDR.DLL, but none have both. The wrapper library works on all platforms, and therefore must look for both and link to whichever it finds.

Hi
I would like to know if the two dll provide the same functionality.
Can we configure the SmartIO ports identically with both dll ? Or is there some limitation with KEYBDDR.DLL (e.g. ports A & B locked on keypad configuration) ?

thanks for any answer

eric

Both SMARTIO.DLL and KEYBDDR.DLL export the same functions and have the same functionality.

#ADSmartio_dll_name

Background information: Keybddr.dll and SmartIO.dll

On many of our products (GC Plus, AGX, Bitsy family, et al), the ADSmartIO controller handles input from the PS/2 keyboard. CE requires that the keyboard driver library be named keybddr.dll. Since we had to put the keyboard portion of the ADSmartIO functionality into that dll, we included the rest as well.

On some other products (e.g. Graphics Master), the SA-1111 handles PS/2 keyboard input. Because there was already a keybddr.dll for that driver, we had to put the ADSmartIO functions in a different library (smartio.dll).

Both DLLs have the same functionality. Only one is included in each build of CE. You can edit our sample source code to display a message that is most informative to you.

Rev 3 Update

We've uploaded revision 3 of this library, which adds a couple WritePort functions that were formerly missing.

Errata
- The WritePort() methods have an error. They are missing the value parameter.
- You might also remove the return statement from the WritePort() methods, since those methods don't return any values.


Edited by akidder 6-Apr-2006: Add erratum about WritePort methods
