"It doesn't work" is not much to go on. So if offer a method I have used to store, retrive and manage my own 2, 3, 4, 5 ... dimensional tables stored in memory or disk or ... . A more experienced C programmer will maybe make it easier; first: int *myInt then: function int fetchMyInt(int x, int y, in...

If you have an oscilloscope take a look. If not, draw a trace with bounce when first pressed, then stable, then bounce when released. Draw two traces. a long press and a short press. bounce bounce bounce stable0 stable0 stable0 bounce bounce bounce stable1 stable1 ... ............................^ g...

It sounds like you may need to study the preprocessor and how that works. In short: #define does not directly put anything in memory; You can use it to do that and a lot more. I recommend that you study a little.

thanks now i can use the ULP without so much pain.

Pulling it up will make it clearly High as compared to "Floating high" . But, if you have a switch on that pin (andit is pulled high) twhen closed will make it low (pin to switch to ground) when you make that switch the signal will bounce and finally settle at low. You need to debounce in software; ...

Do you have a bounce problem? Have you looked at it on a scope? Are you debouncing?

So you are not using an mqtt broker. If so, install and use an mqtt broker.

It is not clear what the problem is. What did you observe?

Using the esp32/Arduino for a very similar task I found the components to be "fragile" and broke them a lot. I used the STA to connect for MQTT and AP for serving a web page for configuration. One thing that I found helpful was to capture all of the events and print them to serial. You may get more ...

I believe that the internal pull-ups *can* be activated by code but I don't think by default are they activated. In your case it sounded like high was what caused the sound generator because:!===> without a signal from the processor they "float" and to the sound driver they appear high. So, the solu...
