That is odd: I use rshell/rsync daily. On Pyboard 1.x I generally use an SD card, but on Pyboard D and ESPx I use flash. The only time I've had problems have been with large numbers of files on an SD card when operations like ls can fail. I assume you've checked the contents of /flash to be sure tha...

Event.set() no longer accepts an optional data argument The official Event class is CPython compatible. The version in my asyn.py library had three differences from the current official one: It is an awaitable class. The .set() method can be called from an ISR. It has an optional data arg. I have r...

You might like to try this. I have tested it under new uasyncio. It isn't particularly efficient, but it does work. I should point out that it is based on the work of Paul Sokolovsky namely his implementation in uasyncio V2. from ucollections import deque import uasyncio as asyncio # Exception raise...

and has no reference to MicroPython (although I haven't watched the videos).

Please could you explain the relevance?

See the ujson library http://docs.micropython.org/en/latest/l ... ujson.html

Code: Select all

import ujson
d = {1:'one', 2:'two'}
with open('my_file', 'w') as f:
    ujson.dump(d, f)

Loading is similar.

This is rarely necessary on a Pyboard. If your filesystem looks OK just go ahead.

You can test for the new version with

Code: Select all

import uasyncio as asyncio
asyncio.__version__

The old version will throw an exception, the new one will issue (3, 0, 0).

@doceave As Kevin says you are using uasyncio in a strange way. I suggest you look at the tutorial in this repo.

The same problem arises with sending. A nonblocking send prioritises immediate return over complete transmission. You can achieve reliable communication with nonblocking sockets, using uasyncio to take advantage of the nonblocking characteristics. Examples are resilient MQTT and MicroPython IOT . In...

It's well worth setting your editor to convert tabs to spaces.

I never use threading - maybe the limit is less. You could run my above script on the threaded build to check this value.
