Re: Comparison of the three Pyboard D models?
The 723 and 767 both have USB HS. The 722 doesnt. The max observable transfer speed over usb fs is around 6-8Mbit/sec. With USB HS you could peak at 400Mbit/sec but I‘m not sure how fast the pyboard can deliver data with that pace - but it will likely be much faster than FS. On the REPL you probably...

Re: Where can I see the internal reference buffer settings for STM32 in micropython?
you can always check the HW registers... e.g. stm.mem32[stm.VREFBUF]
assigning 5 for example activates the 2.5v reference

Re: NRF52: NFC support?
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 - ...

Re: BMI160 9DOF IMU with pyboardV11
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 I‘m not sure if the lsm9ds1 sensor from ST on the SenseHat is a bit outdated now since the board has been around for some time. ...

Re: BMI160 9DOF IMU with pyboardV11
I used the 9DOF sensor on the SenseHat and managed to use it together with peters fusion library that you have linked.

NRF52: NFC support?
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.

Re: [nRF52] How do I increase the amount of flash allocated to micropython's micro file system?
@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...

Re: BrainPad running MicroPython
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...
