To summarise this uses an Adafruit Trinket running special firmware to interface USB devices to microcontrollers such as the Pyboard. The interface between the Trinket and the target board is via a UART.

Supported USB devices include keyboards and are detailed in the URL above.

It has emerged that the feature is deliberately omitted from the Unix build. In my opinion the Unix build should include all MicroPython language features: this is under discussion by the maintainers.

As far as I can see you're right. I've raised this issue.

I think you have mismatched versions of firmware and uasyncio . If you are running the official firmware, the version of uasyncio on PyPi will not run. You need to replace __init__.py and core.py in the uasyncio directory with those from the official micropython-lib . The code on PyPi is only guaran...

Yes, that's how it works. I think that's the best that can be achieved without changing the firmware. It means that you can write my_coro_ref = my_coro() loop.create_task(my_coro_ref) # Do stuff, then asyncio.cancel(my_coro_ref) await asyncio.sleep(0) # Now it really is cancelled and this will work ...

The current official uasyncio V2.0 has an issue whereby task cancellation and timeouts are deferred until the task is next scheduled. This can introduce substantial latency if the task is waiting on a sleep() , sleep_ms() or on I/O. The uasyncio author, Paul Sokolovsky, solved this in his library fo...

I've never heard of a WiFi skin for the Pyboard. Who makes it? Is it an ESP8266 with AT commands?

See my response to your PM. It should be easy to get this working.

No. It would require significant changes. Worse, it would defeat the object of the design. The aim is to have internet facing applications running on a device with an OS, with an internet connection which is under OS control. Hence the inherent unreliability of a WiFi link affects just one interface...

This project evolved since my first post and became a collaboration between myself and Kevin Köck. Key features: The API is similar for client and server applications. It is cross-platform supporting ESP8266 and Pyboard D clients. It supports guaranteed message delivery: a message will be delivered ...
