- Virtual display with user specific dimension
- Up to 4 sub displays
- Two to four physical displays can be combined
- Currently only C API supported
- Physical displays u8g1 and u8g2 are combined:
u8g_t u8g1; // physical display 1
u8g_t u8g2; // physical display 2
u8g_t u8g; // virtual display
int main(void)
{
u8g_uint_t h;
u8g_Init(&u8g1, ...);
u8g_Init(&u8g2, ...);
// setup virtual display, assign virtual dimension
u8g_Init(&u8g, &u8g_dev_vs);
u8g_SetVirtualScreenDimension(&u8g, 128, 127);
// map physical displays on this screen
u8g_AddToVirtualScreen(&u8g, 0, 0, &u8g1);
u8g_AddToVirtualScreen(&u8g, 0, 64, &u8g2);
u8g_FirstPage(&u8g);
do
{
u8g_DrawLine(&u8g, 0,0,127,127);
u8g_SetFont(&u8g, u8g_font_7x13);
h = u8g_GetFontAscent(&u8g);
u8g_DrawStr(&u8g, 10, h, "ABCgdef");
u8g_DrawStr(&u8g, 0, 10+h, "AB");
}while( u8g_NextPage(&u8g) );
return 0;
}
