Connecting Atmel-ICE To Data Gateway Interface

The Atmel-ICE supports a limited Data Gateway Interface (DGI) when debugging and programming is not in use. Functionality it is identical to the interface found on the Xplained Pro development boards powered by the Embedded Debugger (EDBG) device.

The DGI is an interface for streaming data from the target device to a computer. This is meant as an aid in application debugging as well as for the demonstration of features in the application running on the target device.

DGI consists of multiple channels for data streaming. The Atmel-ICE supports the following modes:

  • USART
  • SPI

1) SPI and USART interfaces cannot be used simultaneously.
2) DGI and programming or debugging cannot be used simultaneously.
