5 years ago Try to use i2c driver from greiman instead of slow buggy Wire. I mean run this example https://github.com/greiman/SSD1306Ascii/blob/master/examples/AvrI2c128x64/AvrI2c128x64.ino. Also, call the method to increase i2c frequency to 400 000 instead of default slow one.

5 years ago My guess is that you have a clear display call in your main loop. This will cause flickering.

..You're clearing the display each time through your loop. Remember that there is no buffer with this library.
-Edit-
You're not even using this library in your code? You're using an Adafruit one.

5 years ago Looks like you clear the screen each time you enter loop so it will flicker.
Clearing the screen requires writing 1024 bytes of zero to the display memory.
oled,clear() takes about 46 ms.
Run this code in loop. It flickers.
void loop() {
uint32_t m = micros();
oled.clear();
oled.print("\nmicros: ");
oled.print(micros() - m);
}

2 weeks ago I am facing the same issue as the OP here.
With the Adafruit lib I do clear the display in a loop and it does not flicker.
Using the same code ported to SSD1306Ascii it does flicker.
What is the reason for this? Is it because one is using buffer and the other not?
What are the options to avoid this? Should I use clearField() to just clear the area of interest. The problem with that is that I need to know the length of what I am displaying.

This is likely the reason. SSD1306Ascii does not use a buffer image of the screen.
It will be much faster if you only clear areas that you are not rewriting.
You can use this function to find the length:
size_t strWidth(const char* str) const;

2 weeks ago Thank you. This explains that then.
I found to avoid the flicker is not to clear anything at all and replace the text I want to update. The issue here is that I need to control every length of text I am sending. Hence filling with blank space if the string gets shorter For example if I send "12.58V" then update with "8.23V" it would come as "8.23VV" if I don't fill with space. I found the dtostrf command to be the rescue here (yes because on top of that arduino does no process sprintf with floats arf!).
Well the no buffer story is a good news for me. I am actually switching to this lib because I was facing low RAM with the adafruit lib. So I guess now I don't need to keep about 1k of free ram to be able to run my code with the oled now?
The display is really flickering. If you want my code, let me know. Thanks for response
