3.5.6 Customize
The Customize sub-panel sends commands to upload custom FIR and IIR filter coefficients, upload cus-
tom test bit stream data, start the digital filter, stop the digital filter, and write/read custom EEPROM con-
figuration files to the on-board boot EEPROM. Example data files are included in a sub-directory of the
software installation.
3.5.7 External Macros
Macros are generated within the Macros sub-panel on the Control panel. Once a macro has been built
it can either be saved with a unique macro name to be run within the Macros sub-panel, or saved as an
external macro and be associated with one of the External Macro buttons.
A macro is saved as an External Macro by saving it in the . /macros/ subdirectory using the name
‘m1.mac’, ‘m2.mac’, etc. Depending on the selected name the macro will be associated with the corre-
sponding External Macro button M1, M2, etc.
• M1 = . /macros/m1.mac
• M2 = . /macros/m2.mac
• etc.
External Macro buttons can be re-named on the panel by right clicking on them. The button name will
change, but the macro associated with that button is always saved as ‘m1.mac’, ‘m2.mac’, etc., in the
. /macros/ subdirectory. The External Macro button names are stored in the file ‘Mnames.txt’, also in the
. /macros/ subdirectory.
External Macros allow up to eight macros to be accessed quickly without having to load them into the Mac-
ros sub-panel on the Control panel. These External Macros operate independently of the Macros sub-
panel and are not affected by operations within it, except when a macro is saved to the . /macros/ subdi-
rectory to replace a currently existing External Macro.
Control Description
Load FIR Coef Write a set of FIR coefficients into the digital filter from a file.
Load IIR Coef Write a set of IIR coefficients into the digital filter from a file.
Load TBS Data Write a set of test bit stream data into the digital filter from a file.
Start Filter Enables the digital filter by sending the Start Filter command.
Stop Filter Disables the digital filter by sending the Stop Filter command.
Control Description
M1 - M8 Runs the External Macro associated with that button.
