    • RE: UART communication problem

      OK, I will try Grove A and B. By the way, what's the signal level of UART on Fire? I suspect it's not compatible with RS232 signal. (I see some microcontrollers need a converter to convert between TTL and RS232).

      Thank you!

    • UART communication problem

      Hello,

      I'm trying to use the UART port (grove C) on the Fire to talk to my computer. My computer use a FTDI USB-RS232 converter to generate the serial signal.
      I found I can detect some signal from the fire on my computer, but Fire cannot read the signal from computer. (I used pyserial to send the signal from my computer)

      I guess it's because UART is not compatible with RS232 signal but I'm not sure. Please help if you have related experience.

      Thanks,

    • RE: UIFlow 1.7.1

      I found the "Advanced" function group is missing in the Web version of UIFlow 1.7.1. Is it relocated to somewhere??

    • RE: Is there a deep sleep mode for Fire?

      Hi Felix,

      Thank you for you quick answer. Looks like you're referring to the Arduino library of M5Stack.
      I wonder if there is an equivalent function in UI-FLOW? I'm currently using UI-Flow to program my Fire.
      I can also try to burn the Arduino firmware, but I'm worried if I can control the UI as easily as in UI-Flow.

      Thx,

    • Is there a deep sleep mode for Fire?

      Hello all,

      I'm designing a Fire application which is supposed to be work on battery, and it will be beneficial if I can deep sleep Fire when it's not being used. Is there a way to "Sleep" the unit? Or what's the most common way to reduce power consumption?

      Thank you!
