I do not have your display. I built the paged example from #18 for a Uno with \_1 constructor: ```cpp Using library U8g2 at version 2.26.14 in folder: C:\Users\David Prentice\Documents\Arduino\libraries\U8g2 Using library SPI at version 1.0 in folder: C:\Program Files (x86)\Arduino-1.8.9\hardware\arduino\avr\libraries\SPI Using library Wire at version 1.0 in folder: C:\Program Files (x86)\Arduino-1.8.9\hardware\arduino\avr\libraries\Wire "C:\\Program Files (x86)\\Arduino-1.8.9\\hardware\\tools\\avr/bin/avr-size" -A "C:\\Users\\DAVIDP~1\\AppData\\Local\\Temp\\arduino_build_680476/jxid_ks0108.ino.elf" Sketch uses 9510 bytes (29%) of program storage space. Maximum is 32256 bytes. Global variables use 588 bytes (28%) of dynamic memory, leaving 1460 bytes for local variables. Maximum is 2048 bytes. ``` Paged example with \_F constructor: ```cpp U8G2_KS0108_ERM19264_F u8g2(U8G2_R0, 5, 6, 7, 8, 9, 10, 11, 12, 4, 2, 13, A1, A2, A0); ``` ```cpp Sketch uses 9514 bytes (29%) of program storage space. Maximum is 32256 bytes. Global variables use 1932 bytes (94%) of dynamic memory, leaving 116 bytes for local variables. Maximum is 2048 bytes. ``` Your full buffer example from #15 with \_1 ```cpp Sketch uses 9078 bytes (28%) of program storage space. Maximum is 32256 bytes. Global variables use 588 bytes (28%) of dynamic memory, leaving 1460 bytes for local variables. Maximum is 2048 bytes. ``` Or your code with \_2 ```cpp Sketch uses 9082 bytes (28%) of program storage space. Maximum is 32256 bytes. Global variables use 780 bytes (38%) of dynamic memory, leaving 1268 bytes for local variables. Maximum is 2048 bytes. ``` Or your code with \_F ```cpp Sketch uses 9082 bytes (28%) of program storage space. Maximum is 32256 bytes. Global variables use 1932 bytes (94%) of dynamic memory, leaving 116 bytes for local variables. Maximum is 2048 bytes. ``` You can see that the Full Buffer only leaves 116 bytes of SRAM. The program will _probably_ crash. Yes, life is easier with a Full buffer. Fine for a 128x64 on a Uno. Your 192x64 needs too much SRAM on a Uno. With a Paged constructor means you have to use the firstPage() .. nextPage() construction. But at least it will run on a Uno. David. ---

Here is a demo project that i made with the help of David. It prints greek words in the display. ```cpp #include #include #include #include #define U8X8_HAVE_HW_SPI U8G2_KS0108_ERM19264_1 u8g2(U8G2_R0, 5, 6, 7, 8, 9, 10, 11, 12, 4, 2, 13, A1, A2, A0); void setup(void) {   pinMode(3, OUTPUT);   digitalWrite(3, 0);   u8g2.begin();  } void loop(void) {   u8g2.firstPage();   do     {     u8g2.setFont(u8g2_font_cu12_t_greek);     u8g2.drawUTF8(0,12,"Καλησπέρα - ΚΑΛΗΣΠΕΡΑ");     u8g2.setFont(u8g2_font_unifont_t_greek);     u8g2.drawUTF8(0,30,"Καλησπέρα - ΚΑΛΗΣΠΕΡΑ");     u8g2.setFont(u8g2_font_10x20_t_greek);     u8g2.drawUTF8(0,50,"Καλησπέρα-ΚΑΛΗΣΠΕΡΑ");                }   while ( u8g2.nextPage() ); } ``` ```cpp Sketch uses 19252 bytes (59%) of program storage space. Maximum is 32256 bytes. Global variables use 624 bytes (30%) of dynamic memory, leaving 1424 bytes for local variables. Maximum is 2048 bytes. ``` Thaks for the help. ---
