lv_demo_stress

This is a stress test that executes for a number of iterations and is used to detect memory leaks in the LVGL subsystem.

lv_demo_widgets

This is the standard LVGL interactive widgets test that shows some of the standard LVGL functionality across a series of scrollable tabs.

lv_demo_benchmark

When CYGFUN_LVGL_SYSMON is configured this demo is provided to report some basic performance information for the LVGL configuration. The application includes a slideshow configuration of the widgets as well as performing various LVGL operations prior to that final test.

For example, the following is the tail of the diagnostic output from a run of the test on a stm32f746g_disco platform configured for double-buffering with the system monitor logging directed to the diagnostic LOG output:
