Hi. Could you post some sample code showing a scrolling using the new logBuffer? I’ve tried but all I get are characters that overwrite each other on the screen & never scroll.
display.init();
display.setColor(WHITE);
display.setLogBuffer(5,20);
for (int i=0; i<10; i++) {
display.println(i);
display.display();
display.drawLogBuffer(0,0);
}

In reply to John MacLeod. Hi John. Based on your idea Fabrice Weinberg has implemented this in the new 3.0.0 release of the library!

Love your work on this library – and it’s fast! How hard would a scrolling display capability be? ie a print/println capability with smooth scrolling on reaching the bottom of the display. John

In reply to BroHogan. Care to share your simple "Hello World"-example?

To follow up on previous, I did figure out how to do a basic Hello World display (missed display.display :).

It may interest you that your lib seems to work with ATmega chips with a small change. I have it working with the Pro Mini. Basically it's an "#ifdef ESP8266" around the 2 calls to Wire.begin() to not pass the SDA & SCL. Of course there is not much memory left - ~12k with 2 fonts used.

Again, thanks for a great library.

I'd like to second the previous post. I'm trying to pair down your example, but frankly it's a bit over my head. If you can point me to a basic Hello World, it would be greatly appreciated.

I've been searching for a nice ESP/OLED lib and your's looks like it. Not to mention the font converter.

In any case, wonderful work! I bought you a well deserved beer.
Thanks, John

First of all: thank you for making this nice library. It is the only one that lets me use my I2C-based OLED screens on my WeMos D1 Minis. But I have one question: could you add an extra example? A super-simple example with no frames or overlays. To use when you simply want to access and write to the screen from the loop with simple commands?

All the examples I can find includes several frames. And some times I only want a display to show a distance, the time or something else. I am fairly new to arduino coding and all my attempts to simplify the code ends in a black screen...

Я пытаюсь повторить ваш проект уже 3 недели, но ничего не получается! Мой OLED Display – Sh1106, А Ваши библиотеки с ним не работают! Могли бы Вы Исправить библиотеки так, чтобы они работали с дисплеями Sh1106 и SSD1306? Спасибо. Николай из России.

In reply to Juho.

Hi Juho. Looks I missed your question for almost a month. Well in the meantime I have a good answer: I removed it since now you can add font sizes and styles as you want. You can create fonts by using this tool here: http://oleddisplay.squix.ch/
For me the 2×2 font scaling was a bad workaround to have big characters. Now you can use nicely rendered characters in any font that is available. I might extend the tool in the future to use any font you like…
