5.21 _7200_CheckHalfReady

@ Description

When you use _7200_DI_DMA_Start to sample digital input data and double buffer mode is set as enable. Users must use _7200_CheckHalfReady to check data ready (data half full) or not in the circular buffer, and using _7200_DblBufferTransfer to get data.

@ Syntax

Visual C++ (Windows 95)

int W_7200_CheckHalfReady (Boolean * halfReady)

Visual Basic (Windows 95)

W_7200_CheckHalfReady (halfReady As Byte) As Long

C/C++ (DOS)

int _7200_CheckHalfReady (Booelan *halfReady)

@ Argument

halfReady: 1 (TRUE) or 0 (FALSE)

@ Return Code

ERR_NoError

5.22 _7200_DblBufferTransfer

@ Description

Use this function to copy the input data in the circular buffer to the transfer buffer. It copies half of the circular buffer, either first half or second half, to the transfer buffer.

@ Syntax

Visual C++ (Windows 95)

int W_7200_DblBufferTransfer (U32 *userBuffer)

Visual Basic (Windows 95)

W_7200_DblBufferTransfer (userBuffer As Long) As Long

C/C++ (DOS)

int _7200_DblBufferTransfer (U32 *userBuffer)

@ Argument

userBuffer: the start address of the transfer buffer. The W_7200_DblBufferTransfer function copies half of the circular buffer to userBuffer.

@ Return Code

ERR_NoError, ERR_NotHalfReady
