    • RE: Core2 PortC not working

      @felmue said in Core2 PortC not working:

      GPSRaw.begin(9600, SERIAL_8N1, 13, 14);// GPS init

      Hi @felmue

      Thanks a lot. It works. I small hint in the documentation would be nice.

    • Core2 PortC not working

      I tried GPSRaw.ino on Core2 but get no response from GPS Unit.
      Is there a special initialization required?

    • RE: CoreInk deepsleep

      @felmue It seems to me that I measure not the battery voltage. The voltage is always around 4.8 V and this could be the voltage after the SY7088. So I can use that voltage as an indicator for enough battery voltage only. If I have schematics then I have the chance to a little bit deeper. Until now I did not find the schematics, yet.

    • RE: CoreInk deepsleep

      After looking into Github I must see that the installed library differed from the library at Github now.
      After updating the compilation worked and I can test the internal battery voltage over time.

    • CoreInk deepsleep

      How to deepsleep a CoreInk. The shutdown() gives a compiler error. Any idea?

    • PowerC

      I want to use the PowerC as a backup battery for the small internal.
      I use your program example and it works.
      After switching on the PowerC I can see the external Vbat and seconds later PowerC switches off and I can see the internal Vbat. This is not the expected behavior. Additionally, the switch loses its membrane already (after 20 presses).

    • RE: M5StickC &18650C Hat

      @hugo I do not have this problem.
      Two quick&dirty proposals: 1. double sided tape between M5StickC and the hat or 2. drill two holes into the back of the hat and you can fix the M5StickC by two screws.

    • M5StickC &18650C Hat

      I build a handheld thermometer based on M5StickC, 18650 hat and ENV hat.
      Now I am looking for the possibility to check the status of the 18650 LiPo and show it on TFT (see my blog).
