  • Question on Virtual Screen Support

    Hi there,

    I am currently using emWIn on an embedded system and am trying to implement a Virtual Screen. The actual size of the screen is:

    #define LCD_XSIZE 320
    #define LCD_YSIZE 240

    and I am trying to increase it to

    #define LCD_VYSIZE 480
    #define LCD_VXSIZE 832

    however while I can increase LCD_VYSIZE with no problems I cannot increase LCD_VXSIZE without effecting what is displayed on screen (e.g if I set LCD_VXSIZE to 640 I double the size of everything displayed on screen ). Is there a setting I am missing or is it just not possible to incease the virtual X size on my LCD. The LCD driver is a HX8238.
