@ajb2k3 I wasn't aware of ultrasonic I2C!
Here I've only been able to find GPIO ones
Thank you veyr much for clarification
It's very nice to design UIs with UIFlow
The problem comes if I want to use different "pages", say a main menu and several sub menus.
I think UIFlow needs to handle the "page" concept and be able to select which page is shown from the code
Perhaps each page should run it's own blocks and have a "background" page for all the other code.
What do you think?
