The Data Gateway Interface (DGI) is an interface for handling the low-level transport of data from a target MCU. The DGI is available on a selection of tools and on-board debuggers.
The DGI provides several interfaces utilizing the same API for configuration and communication. Each interface implements an abstraction to a physical communication interface, such as SPI and UART, or represents a service not directly tied to a physical communication interface, such as the timestamp interface.
The MPLAB Data Visualizer is the application used to control and steam Data Gateway Interfaces. The application may be accessed from within MPLAB X IDE or as a standalone program. For more on this application and DGI, see the MPLAB Data Visualizer webpage.
