1.1 LVGL Project Setup

LVGL has been integrated into the M33 SDK, however, the library must be linked into the project. The following steps can be followed to perform this linking:

  • Right click on the project and select "Add Files/Folders..."
  • In the "Add Files/Folders" window, select the "+" sign to add the LVGL library
  • From the "Select files/folders" window, change the dropdown from "Select files to add" to "Select folders to link"
  • Then select the base path of the SDK LVGL library by clicking on the "..." icon near "Path".
    • The SDK LVGL library is located at "C:\ti\mspm33_sdk_XX\source\third_party\lvgl" where "XX" is the latest SDK version.
  • Click "Ok" on the "Select files/folders" window
  • Finally, click "Ok" on the "Add Files/Folders" window
  • The SDK LVGL library should now be included in the project
The library has the most basic configuration and no low level drivers. To configure the library for a specific application and add low level drivers for a specific display, five files must be added to the project and adjusted:
  • lv_conf.h: The main configuration file for LVGL
  • lv_port_disp.h: The header file for the LVGL display driver
  • lv_port_disp.c: The source file for the LVGL display driver
  • lv_port_indev.h: The header file for the LVGL input device driver
  • lv_port_indev.c: The source file for the LVGL input device driver
