    • RE: Error: "BalaC maybe not connect"

      I think the unit is defective. Interesting, because other things work: display, program w/ UI Flow, etc.

      I tried several M5Stick, M5StickPlus, M5StickPlus 1.1. They all work. Only the initial M5StickPlus 1.1 has this issue. And BTW, it behaves similarly when connected to a servo HAT.

    • Error: "BalaC maybe not connect"

      Hello,

      I just receivedd a BalaC Plus Kit. I'm trying to program the StickC Plus from the package it in UIFlow, and I'm getting the error message: "BalaC maybe not connect".

      I already have another StickC and StickC Plus. But they seem to work correctly.

      Any hints on how to debug the issue? Is it possible that the new StickC Plus is somehow borken? Or maybe it's a newer hardware revision, and somehow not compatible w/ the BalaC lib from UIFlow?

      Thanks in advance.

    • Using the RFID reader => speaker noise

      Hi guys!

      I have tried the RFID sample, which works OK. However, the speaker emits a noise when the RFID is functioning. I guess that's related somehow to i2c. RFID uses i2c, and the speaker also (I guess?). 2 questions here:

      • can the 2 work in parallel? I.e. have RFID AND speaker? This is something that I'd probably need soon. They seem to share the same channel (i2c); so multiplexing is involved. So if the RFID is used non-stop, I fear that the speaker won't be able to work.
      • if this is not possible, I'd guess that I need to somehow disable the speaker. But I didn't actually enable. So where does the noise come from?

      Thanks a lot!

      PS: this is my second message; the first one got lost maybe in "moderation" because I had just signed up and the account not yet verified? Who knows.

    • RFID and speaker whine

      Hi there,

      I have ran the RFID sample on a M5Core. It works. However there is a speaker whine happening. I'm not sure exactly what is causing it. Have you got any hints?

      Thanks!
