  @Kabron The benefit is that it can be used as an offline programmer. Love this idea in that I don't need to use a computer to program a few various HEX/BIN files to several different chips.

  Once the partition.cvs table is converted for Arduino IDE, it made it simple to change the fat image for updates.

  The project is set to be compiled with Expressif-IDF/IDE.
  Modify the html / display code prior to fit your needs (Like updating to English to avoid confusion if you're trying to use the in program ability to upload files).

  Hello @wrs642

  from this and your previous post I would guess that there is no battery connected or it is not charged (enough).

  Thanks

  Hello @robouden

  hmm, running UIFlow2 on my M5CoreS3 and measuring current on USB-C I get about 140 mA / 5 V.

  Is your M5CoreS3 maybe charging the battery?

  Thanks
  Felix

  Hello @Schnoble

  clever! Maybe you could put your modified version into an Execute mpy code (eg. import)? This block can be found under System.

  Thanks
