    @world101

    Electrical engineer and logical thinker that loves a challenge to figure things out. I’m a DIY/maker that likes to tinker with IoT devices and 3D design/printing. I’m not good at programming, which is why I heavily use uiFlow!

      That’s awesome! Care to share your project and samples? I would like to play around with it.

    • RE: Core and Fire devices are not correct in the Settings menu

      Just noticed it was also noted by @luis in this thread
      https://forum.m5stack.com/topic/2672/uiflow-1-7-1

      This bug report has screen shots of what the issue is.

    • Core and Fire devices are not correct in the Settings menu

      There are a few bugs in uiFlow beta v1.7.1.

      When you select the Core device in Settings, the Hardware menu shows elements applicable to the Fire device (RGB and IMU), which are not correct.

      When you select the Fire device in Settings, it only shows Power. It should also have Speaker, IMU, and RGB.

      By the way, there's no option for M5Stack Grey, which has the IMU, but not the RGB.

    • RE: Noisy while running

      @sodoku

      I just tested both on the same Fire hardware device. v1.7.0 is more quiet than v1.7.1. Not totally silent, but there is a regression when flashing v1.7.1 (it's more noisy).

    • RE: Noisy while running

      It's common. Just search this forum and internet and you will see. My Fire is more noisy than my Core Grey. The Core2 is much more quiet (the audio circuits were redesigned in the Core2 hardware).

      The way to quiet it some in software is to write a 0 to DAC pin 25, however, it doesn't totally silence it. some people's ears (like mine) can still hear some noise.

      There is a hardware mod if you care to do it on your device...

    • RE: [solved]The download button disappears from the screen (Block Editor)

      Strange... it doesn't disappear for me on Safari or Chrome, but I run a larger resolution.

      Try zooming out on your browser settings... it's usually in the View menu of most browsers.
      Or try to press "Control and -" (Windows PC) or "Command and -" (Mac).

    • RE: M5Paper Speaker

      I guess it depends on what you want to do. I assume you want an external speaker, correct? If so, what are your requirements (just buzzer beeps/tones or full wav/mp3 audio) and how do you want to program it (Arduino, uiFlow, or MicroPython)? There are plenty of options out there if you search for I2C speaker.

    • RE: 8Servos Unit

      yep, same as the BalaC, JoyC hat, etc. those batteries charge up via the M5StickC/C+

    • RE: IP5306 charging current is 6 times greater than C/10

      I saved a copy of the IP5306_I2C data sheet from a long time ago. In this table, I see the charge current can be set by the CHG_DIG_CTL0 register (see the formula). I would assume the M5stack designers took care of setting the max charge current with that register bits 0 through 4, though I could be wrong.

      If you want the entire data sheet, let me know.
