LPC4357 driver 7inch lcd,and running emWin-V5.30.HCLK=204MHz, EMC-SDRAM-MT48LC2M32B2TG-6 and EMC-clock is 102M. Then ,i create a emWin page,and loop call WM_InvalidateWindow() to repaint the page,code such as:
h_menu = page_system_menu();
Now ,the problem is that the page is blinking,and i can see the BUTTON on page is cleared and then the BUTTON redraw.
but when i use the emWin Lib-V5.12 to replace the V5.30,the problem is no appear。
