The following example shows how to connect the SPI interface to a terminal.
However, the procedure is the same for any of the other available data sources. The
target code used in this example can be found in Terminal Example Code.
Todo: Select correct tool in the
DGI Control Panel.
Todo: Click
Connect to make a connection to the DGI on the selected
tool.
Todo:
- Click the
SPI checkbox
- Open the
SPI Configuration dialog by
clicking the Gear button next to the
SPI checkbox

Todo:
- Set Transfer Mode to SCK normally low, Read
data on rising edge
- Enable the Force start-up synchronization on CS
option
Todo:
- Open the configuration
panel
- Add a Terminal view to the
Visualizer
- Drag the
source connector from the interface in the
DGI Control Panel into the
sink for the Terminal to make a connection

Todo: - Start the session
- Press the button (SW0) on the
Xplained Pro board
On each button press, LED0 on the board should toggle and a message appear on
the terminal.
Sometimes more than one message appears for each button press. This is an
indication that some debouncing algorithm is needed in the button sample routine. It is
a lot easier to spot this problem by looking at the terminal output than to watch the
LED toggling.
