Tony - I am storing and retrieving persistent d...
I am storing and retrieving persistent data in the non-volatile storage using the Preferences class, but I cann't figure out a mechanism to clear storage. There is a simple method
preferences.clear(); but to trigger it in the UI is a bit tricky. There is a UIButton class but it does not seem to be available for the configuration page. Ideally I would be able to use the setup function to declare a button in the configuration or Signalk page and use the button pressed action to run some contextual code, like clearing preferences. Unfortunately I do not see any way to attach the button to the configuration page or otherwise. Is there a prescribed way of doing this?4 Replies
I want to reset these counts using the UI
@Matti Airas Is there a way to use the UI classes for this or do I need to fork and modify the code to extend the pages in the SensEsp repo? If so, can you point me to which files are rendering the UI?
I found the commit that implements the restart button. I'll just use the same pattern and fork the repo to add my code https://github.com/SignalK/SensESP/pull/718/files#diff-8f68b0c6a3f4288dc058439640fe4b6fa49cef545a087447c028d98a0ffd09ea
Tony, do you need a reset button or can you just expose the value and make it editable from the web interface?
the chain counter example uses an accumulator value, that I believe can be edited on the web interface

I was thinking of a reset button with a confirmation dialog in the UI. This may be beneficial for anyone using NVS
