  • I've hit some problems with the micro:bit - it'll work when running from USB power, but not from battery.

    Right now I think it could be to do with the UART RX pin getting pulled low (and spamming the chip with 0 characters) but I'm really not sure. Is it possible that could be the problem you're having too?

    Espruino runs fine in 16kB RAM - but you might have to adjust the amount of variables it uses (copy from microbit, which I know works). It's just a bit limited by the amount of code you can write - at least until it gets optimised a bit :)

    PS. when you're posting up areas of code, please can you surround them with 3 backticks and a blank line before and after - like this - it makes it a whole lot easier to read :)

    When you get it working you might also be interested in this
    :)
