ULINKplus is an innovative debug and trace adapter that connects to any Arm Cortex-based device. It equips developers with following features:

  • Power Measurement via isolated Power interface. It is synchronized to event tracing making it easier to optimize the energy efficiency of a system.
  • Digital and analog I/O pins accessible from debug views or from debug scripts. This enables you to interact with the target under test or to control automated test stands.
See Kit Contents section for details on the content of the ULINKplus package.
Section Hardware Description gives an overview of the ULINKplus HW interfaces and provides technical characteristics.

The table below summarizes features available via particular ULINKplus interfaces.
