Getting data from the driver buffer
A single call is necessary copy data from the driver buffer to the user buffer. This board does
not
support the function
ADGetDataRaw().
API-CALL
Long EDRE_ADGetData (ulng Sn, plong Buf, pulng BufSize)
Parameter
Type
Description
Sn Unsigned
long
Board’s serial number
Buf
Pointer to a long buffer.
Buffer to copy micro voltages too.
BufSize
Pointer to an unsigned
long
Size of buffer must be passed or number of samples
requested. The returned value will indicate the number of
actual samples copied to the buffer.
