    • screen slide very slow with AppWizard V130_626d

      Hi,

      I used AppWizard V130_626d to design screen slide. The screen slide can't move smoothly and very slow when used PNG picture with Alpha feature. I captured QSPI data and found emwin sent a lot of display XY position data between frame data. Could you please help check if anything wrong? The attached is AppWizard picture. Thanks.

    • Hi,

      please try a different format for you images. High color with alpha isn't really the best in regards of performance.

      Try "True color with alpha, RB swap, alpha inverted". This format requires more ROM but should be way faster

    • Hi Sven,


      Thanks for your reply. I tried with "True color with alpha, RB swap, alpha inverted", but screen slide is still very slow. I used GUIDRV_FLEXCOLOR and GUIDRV_FlexColor_SetFunc(pDevice, &PortAPI, GUIDRV_FLEXCOLOR_F66709, GUIDRV_FLEXCOLOR_M16C1B8); But found emwin sent a lot of xy position data between picture frame data like attached logic analyzer data. That took up a lot of time.


      Best Regards
