    • RE: Cant compile M5ez.h

      @felmue said in Cant compile M5ez.h:

      Hello @EricR

      without downgrading the Arduino ESP32 framework (e.g. using v2.0.3) I was able to compile M5ez with the following three modifications.

      • In M5ez.h disable WPS by replacing#define M5EZ_WPS with #define M5EZ_WPSx.
      • In M5ez.cpp replace info.disconnected.reason with info.wifi_sta_disconnected.reason.
      • In M5ez.cpp replace SYSTEM_EVENT_STA_DISCONNECTED with ARDUINO_EVENT_WIFI_STA_DISCONNECTED.

      Thanks
      Felix

      Thanks a lot! I am starting again to program for M5Stack after a long time and I was having problems compiling M5ez and understanding where the problem was, but you solved this for me!

    • RE: So much noise!

      I can confirm that : I use Arduino IDE and I also hear noise while communicating with WiFi. I also tried the dacwrite instruction without any success. I don't want to do a hardware mod but this is annoying...

    • RE: M5ez, a complete interface builder system for the M5Stack as an Arduino library. Extremely easy to use.

      @rop I thought MyTZ object was already declared in your library, my fault.
      Thank you for your explanation about objects. I misunderstood your previous directions and I thought I must use them to the widget to work. It seems it was a lot easier to do than that! The widgets I need to display are really simple, just a small text or icon reflecting the state of some variable's value, so I think a regular function will work. I'll try one more time. ;)

      @crazyhorse80
      Do you also have problems if you lookup the timezone from code (like with MyTZ.setlocation("Europe/Amsterdam")?

      I tried to put this line MyTZ.setlocation("Europe/Rome") in my setup() function, but I get an error:

      error: 'MyTZ' was not declared in this scope
      

      I also tried to setup TZ in the clock menu at runtime but I can't find the / character on onscreen keyboard...

       
      I'm not sure I could do something that would be more informative than the clock code from M5ez.cpp. Let's walk through:

      [...]

      Hope this helps, otherwise you'll have to tell me what is not working for you, or (better yet) show code that you are trying to make work.

      I think I understood how the clock widget works, but I can't replicate it with my own widget code, here it is:
      this is on a tab of its own named Widgets:

      It should display the string Fx between WiFi and clock widgets (I'll modify that to display a string from a variable if I get it to work).

    • RE: M5ez, a complete interface builder system for the M5Stack as an Arduino library. Extremely easy to use.

      @Rop Hi! Could you consider some changes requests to M5ez?

      • I have some problem with Geo-IP timezone auto-select, it always timeouts and it's only executed once: could you, please, modify this function to retry if timeout occurs?

      • Could you make the actual header to be a "system" header (with title, WiFi and clock widgets) and add a "user" header so the user could put more widgets in it? I ask for this one 'cause I'm planning an app that will require to display few widgets and I have no pixels to show them all. (In case you're not planning to do that, I'll simply add my code to be displayed in the canvas space with a function of my own).

      • And now a more personal request: could you please make a dummy widget complete with all the code to associate a settings menu (with enable / disable widget setting) and the draw code. It'll be perfect if it will simply display a variable value and update every time the minute changes. I've tried to modify the clock widget but I didn't have success with that.

      Thank you in advance!

      It's only a part of what I want to achieve and here I'll try to explain what my project should do when it'll be complete:
      every minute my M5Stack will receive from another Arduino board an HTTP GET request with data and it stores them in global variables and eventually does some operation with them;
      it should have a multi-page view to show data received and stored in variables (one displays data in numeric form, another will display them in graphs, another one will only change screen background color and make some noise based on data received, and maybe some more);
      it also should have access to the menus to change wi-fi and screen preferences and some more options related to my program (sound volume, default page to display on startup and so on).
      I'd also like to have some more widgets:
      one will have to show me if data received is older than one minute (it means I've lost connection with the Arduino board);
      another one will have to show the current energy billing band based on what time and day of week it is.
      The problem with M5ez, and ESP32 in general, is that I've no clue of where to put my code: do I have to do all in loop() function? Or should I register various functions with ez.addEvent()? Or should I do it some other way? I'm a bit confused... Can you show me a proof of concept application using M5ez (even if not related to my needs, so I could understand how it works)?

    • RE: I need help with a webserver project...

      I need the clock... :( I have that same error every 5 / 7 minutes, it restarts and works for a few minutes again and so on...
      Maybe I can do some test without the clock to see if it is the cause of the problem...

      It should be good to explain how to use other tags, too (if any).
      Thank you in advance!
