3.5.2.7.1 Hidden IDE Window

The Latte program runs a number of python scripts in the background to capture and display data from the EVM. These scripts allow for initialization of the device including loading calibration data from the EVM flash memory, launching a live view window with measurement plot and readings, and additional functionality such as reading from the flash and selecting a specific LED current for the device to use. For advance users or users looking for more flexibility when using the OPT3101EVM these python scripts are available in an integrated development environment (IDE) window that is minimized when TI-Latte is launched. The IDE window allows advanced users to customize the existing scripts or write new scripts.

After launching Latte, expand the OPT3004DTS directory on the left hand side of the window under Files by clicking the triangle to the left of the directory name. This displays the OPT3004DTSEVM folder. Further expanding the OPT3004DTSEVM folder will display all the example scripts as shown in the figure.
