  • Looks like they just announced it: https://microbit.org/new-microbit/

    It uses the nRF52833 and can use S140

    I wonder if current builds for nRF52840 would work (with some pin adjustments) ?

  • Already ahead of you. I'm just about to push it live with the 2v08 release. I'd done a port but was under NDA until the announcement.

    The nRF52833 looks like a great chip, but is also a pain. Nordic only support it in SDK17, which has another whole set of pointless file/function renamings which seem designed to make everyone's life difficult.

    So for now, to get something out quick, I'm just using the old SDK12 with a one-liner to allow the second GPIO port to be used. It means only 64k is used right now but that's more than enough for most stuff.

  • Amazing! :D Can't wait until November when a local distributor rolls it out :)

  • Oh, nice, the first one was old tech even at release day but this one is actually quite usable :-)

    Interesting, so it runs including bluetooth? With S132 3.0? maybe the extra ram is only about linker script? or possibly enabling it in bootloader if it needs changing some registers

  • so it runs including bluetooth? With S132 3.0?

    Yes, it's all fine. I haven't found anything that's broken at all.

    Yes, just a new linker script would do it I reckon - but long term it would be good to move to a new SDK I guess. I was almost there but there were just a few too many unknowns to get it working ok.
