Animations - Number "Flip"

[Fishbone69]

Hi. I am wanted to add a cool number flip animation to a clock like the one here: https://youtu.be/KrUJlZK1ct0

I was wondering how to do this in U8g2. I could use a clip windows and scroll the numbers for the seconds and even the minutes since they are all lined up...but when you get to the hours, it wont work because the ":" symbol would flip. I don't think multiple clip windows is supported. Any other ideas? (I love learning from all of the smart people on these discussions!)

Thanks!!

You can change the clip window multiple times, like this: set clip window for hours, draw hours, set clip window for seconds and minutes, draw seconds and minutes.

So you go back and forth scrolling a little each time? (please confirm if that is the idea) That will work if it is fast enough...maybe need an SPI rather than I2C. By the way, I am new to this, but LOVE the work you did on the library...you should be proud!

U8g2 is double buffered. You will draw into uC memory, then later the bitmap is transferred to the display. All scrolling will be in sync and parallel.
