Some time ago i wrote ftDuinoBlue http://ftduino.de/blue , a simple library for the Arduino+HM10-Bluetooth with an accompaning Android app. The idea was to store a simple description of a GUI with the Arduino sketch so that the Android app can read that from the arduino and draw a GUI accordingly. T...

Finally I found the culprit of the low performance under Windows: Pyserials inWaiting() function is extremely slow on Windows 10 and the pyboard.py makes excessive use of that. So I implemented a little buffer between pyboard.py and pyserial which buffers and caches serial data. It will thus reduce ...

A caching wrapper around pyserial gives a ~5% improvement ... under Linux as well as under Windows 10. Unfortunately pyboard.py's fs_get is still ~5 times slower under Win10 than under Linux. And it's purely pyboard.py related. My own old code runs the same speed as Linux on that same Win10 PC.

FYI, are you aware of https://github.com/micropython/micropython/blob/master/tools/pyboard.py -- rather than maintain your own board remote control library. A lot of work has gone into making pyboard.py reliable and efficient. I have now switched to pyboard.py. This actually made up- and download o...

So how do i catch a Keyboard interrupt (or any other exception) without interrupting the loop?

I was hoping that something like this would do the trick: loop = asyncio.get_event_loop() server_task = loop.create_task(asyncio.start_server(serve, "0.0.0.0", 80)) try: loop.run_forever() except KeyboardInterrupt: print("closing") finally: server_task.cancel() But it doesn't. Maybe because the enti...

Thanks for the link. That code indeed tries to solve the same problem by allowing to re-use ports: https://github.com/micropython/micropython/blob/e8bc4a3a5be12ad639b811852337c63e8f1d6277/extmod/uasyncio/stream.py#L138 But that doesn't seem to work. I do have a completely different async server deri...

import uasyncio as asyncio import utime async def serve(reader, writer): t = utime.ticks_ms() resp = b"HTTP/1.0 200 OK\r\n\r\n" + "Ticks = {TICKS}\r\n".format(TICKS=t) l = await reader.read(256) # yield from may not work print(l) for _ in range(100): # More RAM friendly than sending one huge string...

If I understand your need accordingly, I think Damien is cooking something up: Thanks for the response. But ... no, I don't think this is what I am searching for. I don't have a problem including my code into the firmware. This already works. I can add port/esp32/modules/mymachine/Encoder.py This w...

There are discussions about machine.Encoder and machine.Counter classes in github. These are implemented in C. I would like to give a python variant a trial and would like to add it as a frozen class to the machine module so my versions are compatible with the ones from the existing PR's. Is that po...
