you can always check the HW registers... e.g. stm.mem32[stm.VREFBUF]

assigning 5 for example activates the 2.5v reference

thanks for the reply. What if have figured out so far is that nordic has updated their nrfx lib with nfc support. And with some minor mods i was able to compile it with micropython (static assert macros must be defined). Where I‘m stuck at the moment is how to use the different nrfx nfc functions - ...

Do you mean with the bosch sensor? No I cant give recommendations there. The SenseHat though is great value for getting things to work quickly. It may be a bit big though. I‘m not sure if the lsm9ds1 sensor from ST on the SenseHat is a bit outdated now since the board has been around for some time. ...

I used the 9DOF sensor on the SenseHat and managed to use it together with peters fusion library that you have linked.

I wonder if there is some work being done on the NFC support for the nRF52. Other users seems to have asked the same questions so I thought I open a separate topic.

I'm willing to join or help on this issue but need some pointers within the nRF SDK on where / how a possible integration could be done.

@c45713 The the experiements it was basically found that FATFS on internal flash used a bit to much in overhead, at least for nrf51 and in practice also for nrf52. The findings were that 50 pages had to be reserved in order to even make the FATFS structures, then the file storage came on top of this...

there is the mboot bootloader module in the stm32 port, from damien https://github.com/micropython/micropython/tree/master/ports/stm32/mboot basically implements DFU over USB and I2C, with support to write external SPI chips. I think he might use this one in his upcoming new pyboard devices, thats w...

What I‘ve figured is that the nRF port has the micro:bit FS enabled as default which only supports flat file hirarchies (no directories). Also, I see that os.listdir(‚.‘) reports an error about an argument given... both of which might relate to the problems you see. There is a small section in the r...

It doesn't rely upon nor use softdevice.

What I meant to ask was that *if* the softdevice is included (in case you want to use standard Btle functionality too), doesn‘t it interfere with your code (because you are directly manipulating hw registers)?

I‘m wondering how the softdevice coorporate with this... do you include it in your flash output at all?

And just a small thing: please rephrase the title of this thread so it reads correctly („nRF52“) - makes it a lot easier to search.
