Where can I get the display buffer array?

It'd be nice to be able to access the screen as an array (like an XBMP), to allow to take screenshots and even recording through serial port... But is it possible to access the buffer variable? Thank you

u8glib does not store the full buffer in the memory. So there is no such buffer variable.

Oh, I see, everything is stored directly in the display... And I bet there's no way to retrieve the buffer array back from SSD1306... Thank you anyway.

With SPI data can not read back at all. With I2C it would be possible, but is not supported by u8glib
