There is 1.3 schematic,But I didn't find the PCB of 1.3.

There has never been a released PCB design for the "production" micro:bit. Only for the reference design.

Hi, Apologies in advance for the simplistic nature of the question. Not at all, this is a good question and I wish there was a good reference I could point you to, but nobody has really gotten around to it yet. It's ... uhh... on my list. When I use ' pyb.LED(1).on() ', what python library am I acce...

See this thread for more information https://forum.micropython.org/viewtopic.php?f=2&t=8116 In summary, uasyncio is going to be in the 1.13 release, but the current "daily" builds include it. It's likely that you've probably installed the 1.12 release build. Note that the version described in the "l...

I need to write a byte to a GPIO port in a single operation. You can do this without Viper On the STM32 port there's a 'stm' module which gives you constants for most registers. Combined with machine.mem32 you can pretty much do anything. import machine import stm machine.mem32[stm.GPIOA] = ...

Is that as easy as downloading the github zip and run make from the ports/unix folder ? Is there any dependencies on not so standard libraries I should install ? Yes. I'd recommend cloning the repo rather than downloading the zip. But yes cd mpy-cross make cd ../ports/unix make submodules make Othe...

TvE is correct -- a Ctrl-D (soft reset) will reset the entire micropython heap (which includes all imports and Python structures). Kevin is also correct, but I think saying "it still has libraries loaded" is a bit misleading (sorry). There's no dynamic loader or concept of loading libraries, BUT the...

What do you need to know that isn't on the 1.3 schematic? https://github.com/bbcmicrobit/hardware (As far as I know all htey changed was the accel/mag sensors, which is described in enough detail at https://tech.microbit.org/hardware/) I'm not aware that they ever released anything other than a PDF ...

It's not currently possible to disable the UART from the REPL on ESP32. Yes, you're right, the ESP32 only has three hardware UARTs (0, 1, 2). Software UARTs are generally a terrible idea, it's very difficult to make them reliable (due to the timing), especially (counterintuitively) on more sophistic...

What is meant with scratch?

Like writing it from the very basics (i.e. starting with sockets etc).

Much easier just to use a library where someone else has done all the work.

Uh oh.

I spoke to another person who was previously seeing this issue frequently and they claim that it's solid now.

If you have any additional information about how to repro this (or if you have a really minimal test case that I can try) then that would be useful.
