8- and 16-bit MCUs may limit the size of the fonts. Use 32-bit MCUs for optimal performance.
#define USE_FONT_TERMINAL   1
 Use default Terminal fonts.
 
#define FONT_MODE   USE_FONT_TERMINAL
 Selected option.
 
5- Set SRAM memory

6- Use virtual object

From hV_Screen_Virtual.h for extended compability

Note
Declare additional variables if USE_hV_SCREEN_SELF
Virtual object requires ~1 kB bytes.
  • Basic edition: self option
  • Evaluation edition: virtual option
  • Commercial edition: self and virtual options
  • Viewer edition: virtual option
Recommended: USE_hV_SCREEN_VIRTUAL
