slow to write?

[ustajan]

Hello all,

I am new to attiny85, and surely very new to tiny4koled. I am using this library to write text to a 128x64 OLED display.

What I notice is that the times it takes to write anything on the screen is quite long. I very, very roughly estimate that
oled.clear() takes ~300ms (miliseconds) to execute, while every line written to the screen take additional ~60ms per line.

Is this normal? Is this a reflection of attiny85s intrinsic slowness, the library's limitations, or something that perhaps I am doing very wrong?

I am copy-pasting the relevant part of my code:

void updateDisplay() { //gets called every time millis()%5000==0.
  oled.clear();

  oled.setCursor(0, 1);
  oled.print("blah blah blah blah");
  oled.setCursor(0,2); 
  oled.print(F("ms: "));
  oled.print(millis());
}
