The GUI Register Values can be saved to a configuration file for later use. The configuration file saves the GUI and ULC1001 register map state. With this feature, Calibration Mode can be skipped if the GUI configuration is saved just after Calibration Mode has been run, and a configuration file with calibrated files is loaded. Additionally, a configuration header file can be saved for end system integration.
To open and save configuration files, use the File Menu in the Menu Bar or the Save and Open buttons in the Tools Bar of the North Pane shown in Figure 4-9. After a Calibration File is opened, the GUI can take up to a minute to complete the register updates. A complete load of the configuration file is completed when the Read/Write Status Indicator of the Status Bar displays Idle. The Reinit System button in the North Pane must be selected so that the ULC1001 re-initializes the internal variables with the register values written to it's I2C buffer.
The header file can be used to modify the on-board MSP430 software use with the push buttons. This modification is done in the File menu by clicking on File-Save Configuration to Header File. There is an additional EEPROM chip on the EVM that holds part of the ULC1001 header file, specifically the PRAM. The entire header file, including the PRAM, is 46 kb. For new designs, TI recommends to use a microcontroller that can hold the entire header file. In this case, the EEPROM chip is not necessary.
