@ -203,6 +203,9 @@ A5: For SW I2C and AVR architectures: Uncomment
in U8x8lib.h. This will increase speed a lot for I2C on all AVR uC. However the I2C
bus is always driven by this implementation. Other I2C devices will not work on
the same pins.
A6: For HW I2C the default speed for some controllers is set 100KHz. However these
controller often work with higher speed (200KHz or 400KHz). Suggestion is
to test whether "u8g2.setBusClock(400000);" still works.
Q: Umlaut chars or other chars with a unicode value greater than 127 do not
appear on the displays. What is wrong?
