Measurement / Control via MscDll
Steps for "starting Bit I/O data exchange"
o
The function
MSC_SetupStaticChannel
together with the opcode
opcBIO
(0x42) starts the continuous exchange of Bit I/O data
through the MscDll.
Two buffers must be provided:
-
A receive buffer, which contains the current output data,
followed by the input data received.
-
A send buffer, which contains the output data, that shall be send
to the Irinos-System.
o
After calling the function
MSC_SetNotificationMessage
(alternativ
MSC_SetNotificationEvent
or
MSC_SetNotificationCallback
)
together with the opcode
opcBIO
(0x42), the application is
informed every time new Bit-I/O data is available. It is up to the
application whether it uses or ignores this data.
Using notifications is recommended, but not required.
o
The received Bit-I/O data is first stored in an internal buffer of the
MscDll. In order to copy them into the buffer of the application, the
function
MSC_ReadStatic
together with the opcode opcBIO (0x42)
must be called (see following figure). This function must be called
