I'm running an SSD1306 OLED with an ATtiny85 on 1 MHz, using the TinyWire I2C library for ATtiny, and the SSD1306_minimal library for OLED control.
I ran into a lot of problem with the vertical offset first off, but corrected that in the library code through trial and error. However, I can't seem to get rid off the strange dots appearing onscreen.
Anybody have any idea why they appear?
