The application program has access to the the following variables via the k8d.dll:
INITIAL
VARIABLE
TYPE
VALUE DESCRIPTION
DA
Array[1..4] of Integer
0
Contains the data (value between 0
and 255) of the four 8-bit Digital to
Analogue converters
and 255) of the four 8-bit Digital to
Analogue converters
DAC
Array[1..32] of Integer
0
Contains the data (value between 0
and 63) of the thirty two 6-bit
Digital to Analogue Converter
channels
and 63) of the thirty two 6-bit
Digital to Analogue Converter
channels
IOconfig
Array[0..7] of Integer
$0FF
Each bit contains the configuration
of the corresponding channels of
the eight IO-ports. Bit high (1) =
input; bit low (0) = output
of the corresponding channels of
the eight IO-ports. Bit high (1) =
input; bit low (0) = output
IOdata
Array[0..7] of Integer
Each bit contains the status of the
respective channel of the eight IO-
ports. Bit high (1) = channel on; bit
low (0) = channel off
respective channel of the eight IO-
ports. Bit high (1) = channel on; bit
low (0) = channel off
