int16 SpcGetData (int16 nr, int16 ch, int32 start, int32 len, dataptr data)
nr
16 bit integer
number of the board as defined by SpcInit...
ch
16 bit integer
channel to be read
start
32 bit integer
startvalue to be read
len
32 bit integer
number of values to be read
data
huge ptr to data
data space for read values
return
16 bit integer
error code of function like listed below
Reads data from the board from a specific channel. The board must be initialised before. When using ISA boards, all installation
parameters must be set before (address, installed memory, ...). The Start and Len parameter are implemented on all PCI boards. On
ISA boards the whole data will be read in one turn. The read out data is in the twos complement format and could be directly used for
data processing as standard integer values.

The board is not initialised yet. Use the function
SpcInitBoard
or
SpcInitPCIBoards
first.-
