3.2.1 Latte User Interface

The Latte UI is split into eight windows (labeled 1 to 8) with the following functions:

  • Window 1:

    This window (also called Scripts) shows the list of python scripts available that generate the register commands to configure the AFE7952EVM. The script files shown are located in the ..\Documents\TexasInstruments\AFE79xxLatte\projects\AFE79xx\bringup folder. Modify and create new scripts as necessary, which appear in the Window 1 sub-window when Latte restarts.

  • Window 2:

    This window (also called Editor) shows the code in the script currently selected and can be used to modify and save the code as necessary.

  • Window 3 to 6:

    These windows update as the scripts run to configure the AFE7952EVM and mostly are informational.

  • Window 7:

    This window (also called Command Line) is used to enter and run individual commands. Examples of such commands include changing the TX, RX, and FBRX DSA, NCOs, and so forth.

  • Window 8:

    This window (also called Log) displays messages during execution of scripts to display the current status. This window is also used for troubleshooting.
