@jcrfMX There is a lot of info on LVGL Forum that can adress your concerns. @Lazar-Demin is correct in that the errors being reported indicate you have not correctly added the lvgl headers and libs to your include path library paths. There is nothing special about using LVGL in a C++ application compared to any other C/C++ project, the LVGL Forum has numerous discussions related to this but there's nothig unique about LVGL in this. With regard to the Dash and LVGL, the main area you need understand is the lv_conf.h and the driver configuration, other than that the Dash is a like any other LVGL project.
