6.3.2 Macro Scripting Utility
The Macro Scripting Utility in the High Level Page allows the user to create and upload a text file (.txt
extension) with instructions to write to multiple devices and registers simultaneously. After a macro file is
uploaded and run, SigCon Architect generates a log file showing the device slave address, register
address, data written, and data that is read back after each write.
Figure 19 shows the required syntax for
the macro scripts.
Figure 19. Macro Utility Syntax
NOTE: All parameters on the text file should be separated by a tab in order for the Macro utility to
identify and accept the format.
Figure 10 shows an example of a macro script that programs two LMH1297 devices, one with SMBus
Address 0x5C and another with SMBus Address 0x5A. After this file is saved as a .txt file, the user can
run the macro by entering the appropriate file path in the
Custom Macro Scripting Utility box. When ready,
click Run to execute the script.
Figure 20. Macro Utility Example
After the script completes, the log file can be accessed by clicking View Log File and opening the
appropriate log file .txt file. Figure 21 shows an example of a log file based on the macro utility example in
Figure 20 .
