void | ezLCD_set_display_frame (uint8_t frame) |
void | ezLCD_set_draw_frame (uint8_t frame) |
This header contains functions which are used to set the drawing and display frames. The ezLCD+103 contains 20 individual frames which may be drawn to or displayed. So the user can draw different images to different frames and then choose which frame to render on the screen. This allows for seamless image rendering with virtually zero lag. This is advantageous when telling the ezLCD to render vector images (such as true type fonts) which may take some time due to the computations involved in rendering these images. The ezLCD+103 defaults to frame 0 upon power-up.
The diagram below illustrates how this works (simplified down to just 3 frames for simplicity).
void ezLCD_set_display_frame | ( | uint8_t | frame | ) |
This function is used to select the display frame.
void ezLCD_set_draw_frame | ( | uint8_t | frame | ) |
This function is used to select the drawing frame.
