Add    : Add the following function set for Setting CardModel.
         A822_SetCardModel()

******************************

Fix : In interrupt mode, it initialize the channel/config and
      use Counter0 to make a little delay. Fix it to free the
      Counter0.

Nov-27-2000

for Windows 98
Change : The A822_AD_DMA_GetBuffer(), A822_AD_DMA_GetFloatBuffer()
         functions return error-code or A822_NoError. The total
         bytes not returned in this(and later) version.

for Windows 98/NT
Remove : Remove the A822u.CPP, A822u.BAS and A822u.PAS.
         The related constants move into the demo program directly.

Add    : Add the following function set for interrupt.
         A822_IntInstall(),   A822_IntStart(), 
         A822_IntGetCount(),
         A822_IntGetHexBuf(), A822_IntGetFloatBuf(),
         A822_IntStop(),      A822_IntRemove()
         It is recommended to uses the new function set for the 
         interrupt to get the better performance. 
         (The older function set can still works!!)

Change : The data buffer for the interrupt chaged to be allocated
         and freed dynamically. Thus, user's program have to get
         the data before calling A822_IntRemove() or 
         A822_AD_INT_Stop() function.

Add    : Add the following functions for Channel-Scan feature:
         // Channel-Scan List
         A822_ChScan_Clear(),        A822_ChScan_Add(), 
         A822_ChScan_Set(),
         // Channel-Scan A/D with polling Array
         A822_ChScan_PollingHex(),   A822_ChScan_PollingFloat(),

         // Channel-Scan A/D with Interrupt
         A822_ChScan_IntInstall(),   A822_ChScan_IntStart(),
         A822_ChScan_IntGetCount(),
         A822_ChScan_IntGetHexBuf(), A822_ChScan_IntGetFloatBuf(),
         A822_ChScan_IntStop(),      A822_ChScan_IntRemove()

******************************
Nov-14-2000

for Windows 98/NT
Change : Change all the function and constants with the "A822_" 
         prefix.

Add    : Add the following functions:
         A822_SetChGain(),     
         A822_Fast_AD_Hex(), A822_Fast_AD_Float(), 
         A822_AD_Hex(),      A822_AD_Float()

         A822_AD_Float() do the same thing as A822_AD(), but returns
         error-code.

         Users have to call the A822_SetChGain() function before               calling into A822_Fast_AD_Float() or A822_Fast_AD_Hex().
         A822_AD_Float() = A822_SetChGain() + A822_Fast_AD_Float().
         A822_AD_Hex()   = A822_SetChGain() + A822_Fast_AD_Hex().

Change : Replace the A822u_AD2F() by A822_Hex2Float() function.

Add    : Add the A822_SetCounter() & A822_ReadCounter() functions.

for Windows 98
Add    : Add the External-Trigger demo for VC5.

******************************

Change : Change the interrupt architecture to use the event object.

Update : Change the user interface for all of the demo programs
         for Visual C++ 5.0.

Nov-15-1999

for Windows 98/NT
Fix    : Remove the diagnostic program "A82xDiag.exe" (for DOS),
         and add the diagnostic program "Diag.exe"  (for Windows 
         95/98 and Windows NT).

Update : Change the user interface for all of the  demo programs 
         for Visual Basic 5, Delphi 3 and Borland C++ Builder 3.

Update : Change the format of user manual to .PDF.  The user may
         need to free download the Adobe Arcobat Reader at
              http://www.adobe.com/arcobat/

Add    : Add the user manual "CallDLL.pdf", it describes how  to
         call the DLL functions with VB, VC++, Delphi, BCB.

Add    : Add the user manual "ResCheck.pdf", it describes how to
         check the resoures on Windows 95/98/NT.

******************************
Apr-22, 1999 

for Windows 98/NT
Add    : The user manual add the description of 
         A822_SetTriggerMode().

Fix    : Use the same  user manual  of software of A822-PGL/H
         for Windows 95/98/NT. But,the functions of DMA still 
         support Windows 95/98 only.

******************************
Apr-19, 1999

for Windows 98/NT
Add    : Add the function A822_SetTriggerMode() to select the 
         Internal Trigger  or  External Trigger. The  default 
         value is setting to "Internal trigger mode". 
         The values are list as followings :
             0:Internal trigger mode
             1:External trigger mode

Fix    : The Counter1 and Counter2 used for pacer trigger in 
         Internal Trigger Mode. The Counter1 and Counter2 can 
         be used by the user in External Trigger Mode.

Fix    : The function A822_Check_Address() always return 0 in
         the  External Trigger Mode. Thus,  the user must set 
         the  trigger mode by  A822_SetTriggerMode( )  before 
         call the function A822_Check_Address( ).

Add    : Add the demo of "External Trigger"/"Internal Trigger" 
         to the demo program of "Interrupt".  

================================
Note 1: The A822_DELAY() use the Counter0.
        The unit in A822_DELAY is 0.5 uSeconds.
        2MHz ==> 2000K/Seconds
