@kuriko Turns out there is an extra comma in there ("int32_t, x"). So a typo on the website (which I copied). But Although it compiles now I still could not figure out the last parameter. The doc says "uint8_t font" but thats something else then "IFont* font". What is 2 in your example?

@Kabron It was a friendly 'btw'. There is not a bug or a problem. It works fine for me on 2.3.4. Relax and use the version you prefer.

Hello @LordInchcape not that I know of. That said, have you tried to see what Micropython code UIFlow2 produces? Thanks Felix

Hey @felmue, thanks, this did solve all the issues! Didn't know that I can solely rely on the Unified library without any further changes. Do you know if this is intended, and if so, why does the Board-specific library exist? Thank you so much for your help!

@SirMichael I found what I was looking for, a simple sketch to create a button. I did some minor massages, taking from the events_buttons_gestures_rotation.ino and figured it out. #include <M5Core2.h> ButtonColors on_clrs = { RED, WHITE, WHITE }; ButtonColors off_clrs = { BLACK, WHITE, WHITE }; Button myButton(10, 10, 80, 60, false, "Button", off_clrs, on_clrs, TL_DATUM ); void setup() { M5.begin(); M5.Buttons.draw(); } void loop() { M5.update(); if (myButton.wasReleased()) Serial.print("* "); } Sir Michael

Hi @scobb, did you solve the problem? I'm currently working on a "macro board" with the M5Dial. I can't seem to find a way that the dial communicates with my computer, but I already saw an OBS controller on YouTube which really bothers me because their is a way but I can't find it. Also the OBS controller is not public so I cannot use the code from it.

@wzemann I have the same problem, restore the original firmware, are You solved? Thanks Alberto

@avmg2502 How is it crashing? What is the error message?

@kuriko i wanted the code to read in Fahrenheit . But also the issue is that it’s the reading the i2c connection but in UIFlow it does.

Hello @ScheduleDisplay I am glad to hear it works for you now. Yes, the battery will drain much faster when using ESP32 deep sleep or light sleep compared to a full shutdown. You can find the currents for all three modes here. Thanks Felix

@Paulskpt which library are you using for ui? m5gfx or lvgl?

@guarthur see below sample from example and sample from uiflow [image: 1732522355498-snip_m5c3.jpg] [image: 1732522368550-snip_m5c2.jpg] check that correct gpio is declared

I see that 50 people saw my post. Nobody out there that had similar experience or knows / saw about a solution?

@robski I am not sure about your question - are you asking about the main code or the sound making code? I have tried a lot of different approaches to get an alarm sound but nothing worked. Last try was with https://github.com/Hagtronics/M5Stack-Core2/tree/main/Sound but with no success. I just need any working piece of code that makes a beep sound and I will add it to my main code.

@ioamas No you do not need a SD card. Just install drivers, plug in and press upload button. https://docs.m5stack.com/en/core/core2

@Krmiller Maybe you should look at the source code of the library to see what it does directly when connecting to the first/second client...I think it's still related to the blockage

@alecdvor Maybe this function blocks the code that follows it?

@gdbongle said in Writing serial output from sensor to USB stick connected by M5Stick's onboard USB-C port: I'm trying to get data from a sensor connected to my M5Stick and put it in CSV format to be written to a USB stick for later processing (including timestamps) but I'm not sure where to begin, nor have I found anything of relevance on the forums/docs. Is there somewhere I can begin? writing in to SD card would be one to start from I think
