Hi Oliver
Today I have finished the u8g2 support for the 128x128 Grove OLED (<LINK_TEXT text=“https://github.com/olikraus/u8g2/wiki/g … tudio-oled”>https://github.com/olikraus/u8g2/wiki/gallery#22-apr-2019--sh1107-128x128-seeed-studio-oled</LINK_TEXT>). U8g2 support different text orientation (<LINK_TEXT text=“https://github.com/olikraus/u8g2/wiki/u … tdirection”>https://github.com/olikraus/u8g2/wiki/u8g2reference#setfontdirection</LINK_TEXT>).
Only drawback is: You must install the latest u8g2 beta release (2.26.2), which is available for download here: https://github.com/olikraus/U8g2_Arduino
Once you have downloaded the zip file, you can install u8g2 via the Add zip library menu of the Arduino IDE.
