3.1.4 Data Gateway Interface (DGI)
Data Gateway Interface (DGI) is a USB interface for transporting raw and timestamped data between on-board debuggers and host computer-based visualization tools. MPLAB Data Visualizer is used on the host computer to display debug GPIO data. It is available as a plug-in for MPLAB® X IDE or a stand-alone application that can be used in parallel with MPLAB® X IDE or Atmel Studio 7.
Although DGI encompasses several physical data interfaces, the AVR128DA48 Curiosity Nano implementation includes logic
analyzer channels:
- Two debug GPIO channels (also known as DGI GPIO)
