Usually, a sequence like this is used:
|
|
u8g2.clearBuffer(); // clear the internal memory
|
|
u8g2.setFont(u8g2_font_ncenB08_tr); // choose a suitable font
|
|
u8g2.setCursor(0,20) // set write position
|
|
u8g2.print("Hello World!"); // write something to the internal memory
|
|
u8g2.sendBuffer(); // transfer internal memory to the display
|
|
|
|
In order to speed up the display content rendering for any modified text,
|
|
we could drop the clearBuffer command and just overwrite the previous string:
|
|
|
|
u8g2.setFont(u8g2_font_ncenB08_tr); // choose a suitable font
|
|
u8g2.setCursor(0,20) // set write position
|
|
u8g2.print("hello there"); // write something to the internal memory
|
|
u8g2.sendBuffer(); // transfer internal memory to the display
|
|
|
|
This will only work if:
|
|
- Background is drawn
|
|
- All gylphs have the same height
|
|
Additionally some extra spaces are required of the new text is shorter than the
|
|
previous one.
|
|
|
|
To draw the background: use font mode 0
|
|
To ensure that all glyphs have the same height, use h or m fonts.
|
|
|
|
u8g2.setFontMode(0); // write solid glyphs
|
|
u8g2.setFont(u8g2_font_ncenB08_hr); // choose a suitable h font
|
|
u8g2.setCursor(0,20) // set write position
|
|
u8g2.print("hello there "); // use extra spaces here
|
|
u8g2.sendBuffer(); // transfer internal memory to the display
|
|

U8g2lib Example Overview:
|
|
Frame Buffer Examples: clearBuffer/sendBuffer. Fast, but may not work with all Arduino boards because of RAM consumption
|
|
Page Buffer Examples: firstPage/nextPage. Less RAM usage, should work with all Arduino boards.
|
|
U8x8 Text Only Example: No RAM usage, direct communication with display controller. No graphics, 8x8 Text only.
