3.3 Configuration file generation

Using the STSW-WPSTUDIO makes generating the Configuration file quite simple – the user can do so by

clicking the “Save TX” button in the TX Registers tab or the Common Registers tab, entering a configuration ID

number (used for version control) and pressing OK. The GUI then asks for a save destination. After choosing a

location, the Configuration is saved as a .memh file in the selected folder.
