Your display has a ST7565P controller. Please go to the devices table. You will
finde several constructors for the ST7565 controller. You have to check them
one by one. There is no advice which is the corrent one. Let me know if none of
the available ST7565 devices is working.

- no one from them had worked, so I started to modify them and this works
U8GLIB_DOGM128 u8g(13, 11, 10, 9, 8); // SPI Com: SCK = 13, MOSI = 11, CS = 10,
A0 = 9 , RST = 8
- I had to connect the RST signal (PIN 13 on the display PCB and PIN 8 on
Arduino)
- I tried to work with 3,3 V to test it but working voltage level of the device
is 5V as it is stated on ebay webpage
- I run the graphic example Graphicstest.pde but it is shifted by half of the
display
- it was same with ADAFRUIT driver st7565.cpp and there helped to change this
line
// a handy reference to where the pages are on the screen
const uint8_t pagemap[] = { 3, 2, 1, 0, 7, 6, 5, 4 };
to
const uint8_t pagemap[] = { 7, 6, 5, 4,3, 2, 1, 0 };
and it has worked. How can I correct it in your library?
Thank you.
Pedro

It would be great if you could provide a picture of your screen which shows the
wrong content, including the name of the device (U8GLIB_DOGM128) and example
which was use to generate this screen.
Thanks,
Oliver

So, I had tried u8g.setRot180() and it helped :).
My next issue is how to delete the random dots behind 0,0 position - can be
seen on the attached picture. According to the data sheet the ST7565P is
controller for 65x132 dot matrix LCD.
The code is here:
#include "U8glib.h"
U8GLIB_DOGM128 u8g(13, 11, 10, 9, 8); //SPI Com: SCK = 13, MOSI = 11, CS =
10, A0 = 9, RST = 8
void draw(void) {
// graphic commands to redraw the complete screen should be placed here
u8g.setFont(u8g_font_unifont);
// u8g.setFont(u8g_font_osb21);
u8g.drawStr( 0, 22, "Hello World!");
u8g.drawVLine(0,0,64);
u8g.drawVLine(123,0,64);
}
void setup(void) {
// flip screen, if required
u8g.setRot180();
}
void loop(void) {
// picture loop
u8g.firstPage();
do {
draw();
} while( u8g.nextPage() );
// rebuild the picture after some delay
delay(500);
}

Hi
It is correct, that the controller supports 132x65. This is one of the
problems, because the visible part might be shifted to any location. In fact it
depends on the display. But some of the other devices might work better. So,
please check if
simply replace U8GLIB_DOGM128
with one of the following constructors.
U8GLIB_LM6059
U8GLIB_LM6053
U8GLIB_NHD_C12864
U8GLIB_64128N
Is one of the other four devices better?

U8GLIB_LM6059
U8GLIB_LM6053
- need to modify the contrast in file *.c setting it to
0x001, /* contrast
- you can find the result with preset contrast - picture with black screen
U8GLIB_NHD_C12864
- I would modify the contrast little bit
U8GLIB_64128N
- is the solution !!! ;)

Thanks for the huge amount of pictures :-)
So i assume, that you found a suitable u8g device for your display.
Additionally i would like to mention, that there is a "setContrast" command
also available in those cases, where the content is correct, but the contrast
level wrong.
If there is nothing else to do for me, i would close this issue.
Have fun,
Oliver

Oli, Thank you very much for your help and your excellent project.
To summarize it for ST7565P
constructor: U8GLIB_64128N u8g(13, 11, 10, 9, 8); //SPI Com: SCK = 13, MOSI
= 11, CS = 10, A0 = 9
and some pictures
