    To fix issues with M5Burner on Mac, ensure you’ve installed the correct USB-to-serial drivers (like CP210x or CH340). Run M5Burner using Rosetta if needed. Allow app permissions via System Settings > Privacy & Security. Always download the latest M5Burner version compatible with your mac.

    Hi, the LEDS are self addressable so only need one I/O pin to control all of them

    @babygirl1248 i know you can write special code for the rtc, but have never try. Each time the esp32 is running, you can update the clock and after doing its job, calculate the time it should sleep to wake up at your selectede time and then make it sleep for that amount of sec.

    ATOMDTU UIFlow Error

    Hello @MTal upon closer look I don't see how waiting while Check network registration < 6 would make any sense. The command, I guess that it issues, is: AT+CREG which would yield something like: +CREG: 0, 1 if connected to the home network or +CREG: 0, 5 in case of roaming. You could add a print of the result code of check network registration to see the value you get. If it's 1 or 5 then the modem is registered to the network and you could change the code accordingly. BTW: Interestingly on the product page there is a Chinese version of the UIFlow code which omits the registration check. (I wonder why.) Thanks Felix

    @babygirl1248 said in Audio library or function?: Hello, I am trying to find a way to play wav files off of my SD card. I have a project I'm trying to integrate audio into. I tried one I don't remember the name of but it was a i2s library. This worked when and if it wanted too... I'm in the core 2 using arduino ide. Any recommendations would be greatly appreciated! Thank you for your time. I have tried the esp8266audio library. and its not working.

    Hello @Leo05 hmm, not sure why GPIO27 didn't work - it's marked as GPIO on the M5 Bus - should be free to use. I assume you've set it to output first? If you're not stacking a module which requires a serial connection GPIO13 and GPIO14 should be usable too. If you are not using I2C on the Groove port then GPIO32 and GPIO33 should be free too. Also GPIO35 and GPIO36 are free, afaik, but those two can only be inputs. Thanks Felix

    Hello @babygirl1248 it's included in the M5Core2 begin() function: M5.begin(true, true, true, false, kMBusModeInput); two values; the first is the default: kMBusModeOutput (=0): powered by USB or Battery kMBusModeInput: (=1): powered by outside input Thanks Felix

    @oscillator said in MP3 from internal memory? Core2: https://forum.m5stack.com/topic/143/lesson-6-1-speaker-mp3-player That was written for the original M5Stack in Arduino and so due to so many changes in Arduino does not work any more. @dimi are you still around?

    Work around found: Fresh/clean install of Arduino Install M5Core2 in Library Manager & opt to include all 15 dependencies (will fail with "no protocol:" error) Install manually the 5 remaining dependencies that failed (MFRC522_I2C,M5_BM8563,M5_ADS1100,M5_ADS1115,HX711 Arduino Library,PCA9554) Install M5Core2 v0.0.1 in Library Manager (downgrade) Update M5Core2 in Library Manager to latest version (0.0.6), will list 0 dependencies and ask if you would like to install them, but select "Install 'M5Core2' only". Can now compile and run helloworld example (and others too). Confirmed same install problems encountered on a second PC, and same work around solved it. Arrgh~! Shouldn't be this messy/difficult.

    Hi...I’ve begun using a W5500 on a WIZ850io board. I am employing a microcontroller to conversation to the W5500 over the SPI. I can compose and arrange the gadget, but when I perused back I get mistakes on two out of each four bytes (when bit 1 is set to 1). https://www.7pcb.com/
