Web app spinner

[RGV250]

Hi,
I have a counter for development just to show that the ESP32 is running and I am getting comms to the web app. It also it shows the web page is responding.
I was going to delete it later but then I thought it would look good if I could put a small icon in the corner just going round and round so I know all is good. I could just have the counter but that is boring.
There is nothing like this so I wondered if I could use a gauge to show 360 degrees and have the count running 0-359 so the needle would just rotate. but that is fixed so will not work.
I think it would be a good addition to show timers etc.

I did think of using a 7 segment display with the segments doing a figure of eight but that would be a lot of code for just a visual effect.

Thanks for the suggestion. I'll look into it.

The 7-segment display is fairly easy to implement too - if you can write the data to the display register.

Just need to calculate a 'character set' (for example for a rotating star) and then output at intervals.

For real fireworks - there is the 16 segment display (Though the one I did didn't work in simulation)

there is the 16 segment display

I could not find that, probably reserved for the elite
Also there was no example in the web app help but there is for the app developer. Can I assume they are controlled the same and just an oversight.

Hi,
Not quite a spinner but better than a counter, scrolls round in a figure of 8.

Hi,
A bit of disappointment there, I migrated the macro to my project, added a 7 segment indicator and got loads of errors.
Unfortunately there is no "Show Segments" macro in the web app 7 segment indicator

There is a SetRawValue macro which should allow you to set segments individually.

Hi Steve,
I must have miss read the reply, I thought it said set segment which is not available in the web app 7 segment component.
There is no help for the SetRawValue option but no idea how to use it.

That macro takes a byte value (0 to 255) and each bit in that value corresponds to a specific segment. So 0xFF (i.e. 255) would set all on.

Here's a small example that shows the values and which segments are showing:

Use the switches to control each individual segment. The hex value is the value that you can pass to SetRawValue.
