Embedded Debuggerʼs Data Gateway Interface

The Xplained Pro family of boards contain an Embedded Debugger chip. It has a Data Gateway Interface (DGI) that lets the MCU easily communicate with the Data Visualizer through either its SPI or TWI interface, or by GPIO pins.

Figure 1. The Data Gateway Interface

In the Data Visualizer, the DGI Control Panel is the module that communicates with the Embedded Debuggerʼs Data Gateway Interface. When the board is connected to the computer with the USB cable, it can be selected in the control panel. A list of available interfaces will appear. Enable one or more of them by checking the boxes. In the figure above, the SPI interface is enabled. The MCU can now communicate with the Data Visualizer on its SPI port.
