Figure 3-24. RTDX Data Flow between Host and Target
3.7.3.1 Target to Host Data Flow
To record data on the target, you must declare an output channel and write
data to it using routines defined in the user interface. This data is immediately
recorded into an RTDX target buffer defined in the RTDX target library. The
data in the buffer is then sent to the host via the JTAG interface.
The RTDX host library receives this data from the JTAG interface and records
it. The host records the data into either a memory buffer or to an RTDX log
file (depending on the RTDX host recording mode specified).
The data can be retrieved by any host application that is an OLE automation
client. Some typical examples of OLE-capable host applications are:
Visual Basic applications
Visual C++ applications
Lab View
Microsoft Excel
Typically, an RTDX OLE automation client is a display that allows you to
visualize the data in a meaningful way.
3.7.3.2 Host to Target Data Flow
For the target to receive data from the host, you must first declare an input
channel and request data from it using routines defined in the user interface.
The request for data is recorded into the RTDX target buffer and sent to the
host via the JTAG interface.
