  • screen slide very slow with AppWizard V130_626d

    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 LeoYan

    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.
