      @gachapo Thanks for persevering with this as I got my M5 to day and was getting confused lol. Without this link I would never have got it up and running so thanks for the link as that has kept me from throwing it out of the window.

      Hiya, My name is Matthew, I'm in love with M5Stack products, they're not too publicly discerning, and allows me to move my projects around with ease! I love AI and I have 3x m5 sticks, each one has its own uniqueness and I love trying to make things work with them, like my tello drone. I'm still learning about unitv2 but when they update the firmware for the access point i'll be able to have a lot more fun! - See you all on the stackside!

      For anybody else looking at fixing the issue with multiple simultaneous button presses it seems it can't be done. Having dived into the M5Core2 source the events generated for two button presses, e.g. A & C, are press for A and move for A. This looked like a deeper bug (since the second should have been identified as C), so going further in I found that an else branch wasn't refreshing the currently identified touched button on second press (C) in the method "doEvents" in touch.cpp (it doesn't help the code isn't documented, isn't single responsibility and has an arrow antipattern too). Fixing that bug, so the correct button is refreshed, showed that two events together did not produce presses for A & C but instead (I assume - I'm fed up at this point) the hardware averages the presses' coordinates and declares it's button B(!) that is pressed. If you have old Core 1 code you're porting that uses two simultaneous button presses I'd suggest changing the code to double taps of a single button instead which is the workaround I'm about to use - to remain consistent this behaviour is both on Core 1 and Core 2 More formally, I should have read the file header in touch.h earlier: the M5Stack Core2 touch display is only multi-touch in one dimension. What that means is that it can detect two separate touches only if they occur on different vertical positions. This has to do with the way the touch screen is wired, it's not something that can be changed in software. So you will only ever see two points if they do not occur side-by-side. Touches that do happen side-by-side blend into one touch that is detected somewhere between the actual touches.

      Hello, I realize this topic is very old but I'm trying to compile the MultiApp Advanced firmware. I'm getting several compile issues: src/Apps/WiFiWps/WpsConnect.cpp:30:12: error: 'struct esp_wps_config_t' has no member named 'crypto_funcs' src/Apps/WiFiWps/WpsConnect.cpp:30:28: error: 'g_wifi_default_wps_crypto_funcs' was not declared in this scope src/Apps/WiFiWps/WpsConnect.cpp:90:27: error: no matching function for call to 'onEvent(void (&)(arduino_event_id_t, system_event_info_t))' src/Apps/WiFiWps/WpsConnect.cpp:90:18: error: invalid conversion from 'void ()(arduino_event_id_t, system_event_info_t)' to 'WiFiEventSysCb' {aka 'void ()(arduino_event_t*)'} [-fpermissive] *** [.pio\build\esp-wrover-kit\src\Apps\WiFiWps\WpsConnect.cpp.o] Error 1 lib/ESP32Audio/src/AudioOutputI2S.cpp:190:10: error: 'i2s_write_bytes' was not declared in this scope *** [.pio\build\esp-wrover-kit\lib803\ESP32Audio\AudioOutputI2S.cpp.o] Error 1 I did clone the git repo today, so everything should be up to date. Looks like I'm missing some library? Thanks, Brian

      I'm struggling with edgline but just realized the code which is automatically generated is not compatible with LVGL 8.x, only version 7. Looks like they have not updated the tools since a while, not even sure if they still want to maintain it. I am going back to old school manual coding...I don't mind writing lines of code but I am bad at designing UIs and EdgeLine seemed to be my savior (but not anymore unfortunately)

      @dpharris in the FS root path has already had main.py file you could modify it. when you select the app mode(purple) main.py will be exec. if you are use UIFlow, you need to download the program, not just exec it. then it will auto setting this program for auto-start running. if still not work, pls check the serial log
