Re: [nRF52] How do I increase the amount of flash allocated to micropython's micro file system?
Updating some info that may be useful about microbitFS on nRF boards with MicroPython : - by default, ports/nrf uses microbitFS as file system, see : * issue #6194 "nrf: internal flash filesystem/storage not implemented with VFS" : Today, microbitfs (MBFS) is default internal flash filesystem for al...

Re: How to disable wifi on ESP32
It is not currently possible using MicroPython mainline/official, see this GitHub issue #6219 "[ESP32] Read from ADC2 Pins".
But the MicroPython ESP32 Lobo firmware supports ADC2 .

Re: Better way to Trigger A+B Buttons
See this GitHub issue #470 "Docs - Add discussion on how to detect "simultaneous" press on button a and b" . So this example works : from microbit import * while True: # Solves issue 1 sleep(50) # How long sleep is "just enough"? # Solves issue 2 (a, b) = (button_a.was_pressed(), button_b.was_presse...

Re: Run two funktions at the same Time on ESP32
Another hardware, K210 boards with Lobo firmware has the option :
Running two independent Micropython instances on two K210 cores is supported.
Rich set of functions for data exchange between instances is provided.

Re: MicroPython firmwares with "'MICROPY_PY_REVERSE_SPECIAL_METHODS'" enabled ?
Any comments about drawbacks of "MICROPY_PY_REVERSE_SPECIAL_METHODS" ?
Otherwise I'll always use "MICROPY_PY_REVERSE_SPECIAL_METHODS" in my new firmware builds for Pyboard's, ESP8266, ESP32, Pycom, etc.

Re: Iram1_0_seg overflow with native decorator
See line 183 above : frozen modules are kept in IROM. But running @micropython.native decorator needs IRAM if you have not configured "esp.set_native_code_location(start, length)" to use IROM. I don't have any experience with "esp.set_native_code_location(start, length)", so it is better to have opi...

Re: Iram1_0_seg overflow
Sorry, I think my answer is not a solution for your case with @micropython.native decorator (but it is for native C user/external modules).
IRAM size is fixed, AFAIK. So there is maximum size of code using decorators. But try to use "esp.set_native_code_location(start, length)".
