Yeah, there are a lot of things that the runtime can't do in order to stay "micro". Functions do actually know a little bit about their number of arguments (positional and keyword) but it's handled differently depending on the type of the function (Python bytecode, Python native, builtin, etc), and...

I was wondering if any work has been done to allow further inspection of objects like the python Inspect module. I have been trying to get the arguments for functions to correctly render on the frontend dynamically, normally you would use inspect.getargspec(func) to achieve this, but I see that ther...

Thanks Peter, I sailed right over that when I was looking through your docs, nice. I have it loaded in because I was going to use your scheduling module, started writing my own then came across yours and its far superior. I just need to write a small driver to interact with my main system, enabling ...

The only thing I can think of seems a bit of a hack:

Code: Select all

def iscoroutine(func):
    async def gen():
        print('generator')
    return type(gen) == type(func)

This works but it would be cool if the was a native uasyncio function like asyncio.iscoroutine() that was implemented.

I see

Code: Select all

asyncio.iscoroutine()

and

Code: Select all

asyncio.iscoroutinefunction()

are not used in uasyncio, is there another way to query a generator object?

Hi everyone, I am stumped on this project that uses a task to call driver functions based on commands sent via mqtt. The part that is a pain is the drivers contain some asynchronous functions and some standard functions. I need the task that calls these functions to be able to identify the Async fun...

Well, it was the usb-uart bridge, desoldered it and I am able to get a REPL fine in all applications using my own bridge on UART0.

Bit of pain and detective work, sucks when its the hardware

Ok some more detecting over the weekend, I have noticed I can't get a serial connection through the Arduino serial monitor if I use directly onboard power to either 3.3v or using the onboard regulator with 5v to the vcc pin. It only works with Arduino serial monitor if the board is powered via the U...

Also just tried to serial in via Python with the serial module,

This connected to the port but nothing was received back when I sent a couple of bytes, this worked fine with my other flashed micropython nodemcu.

Just to clarify -- what you're saying is that the Arduino serial monitor works (both with the onboard uart/usb adaptor, and with an external one wired directly to the TX/RX pins on the ESP32), and PuTTY / uPyCraft don't work in either configuration? Yes, that is exactly correct. My guess is that it...
