The chart in LVGL does not display the line data on SF32LB56, and the dropdown list component’s scrollbar is also not showing. I replaced all the lvgl_v8 src source code in the SDK with the one I used in the simulator, but the result remains the same as the original SDK (possibly due to incorrect porting, although it works correctly on Jianguoxin and the simulator). So, how should I properly port LVGL in the SDK by myself, or could there be another issue?
Is the external\lvgl_v8\src\extra\widgets\chart\lv_chart.h component being used?
Yes, there’s also a slight issue with the display of the dropdown control.
Try running lv_example_chart_6 from lvgl_v8_examples. This example displays data when you click on the line. Or do you want to show the data directly on the line itself?
The project migration using examples is indeed correct. Previously, when using lvgl_v8_demos, the chart and dropdown widgets were not fully displayed.
