That's another thing into my e-bay shopping cart...
Thanks Yvan.




Seriously, thanks. This looks like a cool thing to experiment with.

Nice work. Thanks for sharing.
I haven't been able to find this project on your website, so is it possible to get the skecth code from somewhere?

Hello! Do you know if it is possible to connect two displays, but SH1106 and with another library (I use Adafruit's)? The solution I have at the moment is to use 2 arduinos, but the expense would be higher.

could you just use simple simple shift register instead?

Hello Can you possible please share the code with us? I been trying to figure out the ug8lib setup and I'm having aa little hard time following a lot.

Whats the benefit of u8glib over adafruit_ssd1306 libraries?

It's easier to use software I2C which allows you to use any pin for communication. And such lib written in assembler is even faster than hw implementation from AVR
