Re: nrf52480 build and flash

... will find the firmware.hex and firmware.bin files. Either of these should be converted to a uf2 file, so that it can be dragged and dropped to the Adafruit board. To convert the firmware to a uf2 file, we need to use the uf2conv.py script. (see link previous post for uf2conv.py) Perform the conversion, ...

nrf52480 build and flash

Has anyone succeeded in building and flashing Micropython for the Adafruit Feather nrf52480? So far there is no board in the ports. I successfully built micropython for the pca10056 (since the Adafruit Feather nrf52480 is based on this one) make BOARD=pca10056 ...

Re: How to invoke own method from C?

... to the instance rather than just the native struct. (Our PixelBuf class calls `_transmit` on the subclass.) Here is the PR: https://github.com/adafruit/circuitpython/pull/2550 There was definitely work to make the existing native functions correctly get the native struct as they needed it.

Using a ili9341 MicroPython driver ( e.g ili9341 from Adafruit or similar) I can draw shapes, text etc. As an exercise I would like to "Read display identification information (04h)" without using the ili9341 ...

Re: power supply options with output 5V

Yeah that 5V pin is likely just connected to the USB voltage. The board very likely won't have an internal way to generate 5V from 3.3V.

A tiny boost converter is pretty easy to get. Adafruit have them as modules for powering USB devices from lipo batteries.

Or maybe design a new name badge board is better.
