    • RE: [Core2] How to disable speaker tone during booting / power-up?

      Hi guys

      good news. UIFlow M5Core2 firmware v1.10.0.1 finally allows to enable / disable the boot beep via the Configuration menu in the brand new M5Burner v3.0.

      Thanks

    • M5Burner Linux x64 v3.0 - fails to detect ttyACM0

      Hello M5Stack team

      I've been trying out M5Burner Linux x64 v3.0 and while it detects ttyUSB0 devices just fine it fails to detect ttyACM0 devices like the latest M5Stack base v2.61.

      Adding a temporarily sym link like below fixes the issue for me. This leads me to think that M5Burner v3.0 most likely only looks for ttyU* devices.

      sudo ln -s /dev/ttyACM0 /dev/ttyUSB0
      

      Thanks

    • RE: I am looking for internet time M5Stack for Arduino ide

      Hi guys

      @macsbug : thank you for presenting the World Time API as alternative solution.

      @Stoni99 : never mind - I am glad to read you have working code now.

      Thanks

    • RE: I am looking for internet time M5Stack for Arduino ide

      Hello @Stoni99

      your code runs fine on my M5Stack.

      • what happens if you comment out waitForSync()?
      • what is the log output of the crash?

      Thanks

      Hello @Stoni99

      are you sure? From the description Rob developed ezTime together with M5ez for M5Stack.

      What exactly doesn't work for you? Care to share your code?

      Thanks

    • RE: M5 tough remove touch buttons

      Hello @HansDia95

      using UIFlow firmware 1.9.8 on my M5Tough I can simply hide a button and after that it no longer is touchable until I make it show again.

      Have you tried Set touch_button_X hide block?

      Care to share your UIFlow code?

      Thanks

    • RE: Stamp ext IO2 How to program for both Input and Output and RGB on same unit

      Hello @teastain

      yes, it looks like M5Stack engineers only provided a function to set the mode of all pins at together. Shouldn't be too hard to make a function which allows to set the mode of each pin individually though.

      RGB mode: yes, that is what I found as well. Only one LED per pin.

      Thanks

    • RE: RS485 Voltage Levels on COMMU Module

      Hello @RoToR

      one difference between the RS485/TTL unit and the COMMU is that the RS485 circuit in the former is powered by 5 V whereas the latter is powered by 3.3 V. (Not sure why M5Stack engineers decided to use 3.3 V in the COMMU module.)

      I've done my measurements with the RS485 board that was included with the LAN module. When I power it with 3.3 V, with 120 Ohm resistor and not sending anything I get about 1.5 V between A and B. When I power it with 5 V, same conditions, I get about 2.5 V between A and B.

      Thanks

    • RE: AXP192 library SetChargeCurrent in M5StickC but not in M5StickCPlus

      Hello @kazokutchi

      From below comment I assume M5Stack engineers decided to not include the SetChargerCurrent() function for M5StickCPlus.

      // Not recommend to set charge current > 100mA, since Battery is only 80mAh.
      // more then 1C charge-rate may shorten battery life-span.

      That said, have you tired to only copy the function by itself into the corresponding AXP192.cpp file of the M5StickCPlus library?

      Thanks

    • RE: RS485 Voltage Levels on COMMU Module

      Hello @RoToR

      when I send something from the M5Stack and measure between A and B (w/o anything else connected) I get an amplitude of about 1.5 V.

      Have you tried with a 120 Ohm resistor at each end?

      Have you tried w/o the ground wire?

      Thanks
