Re: Embedding MicroPython in a text editor
Does that sound right? Yes that's also basically how most ports' main() function works Wrt string memory, the takeaway is: it's not owned by the caller, and it lives as long as needed. Depends on a couple of things (object representation, whether it's an interned string or not) how this works inter...

Re: Trying to understand how memory allocation is working here...
Yes that's it, displaying on REPL allocates strings. Potentially also Thonny adds some. In any case, for measuting memroy-related behavior in an application one cannot rely on what the REPL says.

Re: C++ module New/Delete and math and C libraries
I think what you're doing would work. Only way to make sure is write tests and/or run your application enough times. First question though is whether it is needed: if the object created by new isn't actually going to be used by MicroPython itself, you can just allocate it from the normal C++ heap (w...

Re: track program execution
If you build with MICROPY_PY_SYS_SETTRACE defined (e.g. make CFLAGS_EXTRA="-DMICROPY_PY_SYS_SETTRACE=1") the sys.settrace (https://docs.python.org/3/library/sys.html#sys.settrace) functionality becomes available. Not completely the same as the trace module, but does track all calls. You can use the ...

Re: Valgrind reporting memory leak with dynamic heap
There's a malloc() for mp_heap but code shows no call to free(), hence it's a leak? That, or valgrind is incorrectly reporting the static memory as leaked.

Re: RFC: How to Test MicroPython
# replace some libs with their c-python 'equivalents' sys.modules['uasyncio'] = __import__('asyncio') ... Perhaps you're aware already, but a while ago MicroPython impleneted 'automatic discovery' of any module prefixed with a u, so the idea is all code simply can do 'import asyncio' as usual and i...

Re: Viewing all class variables created within class instance
For completeness the difference is this: class Foo: x = 0 def __init__(self, y): self.y = 0 print(dir(Foo)) print(dir(Foo(1))) output: ['__class__', '__init__', '__module__', '__name__', '__qualname__', '__bases__', '__dict__', 'x'] ['__class__', '__init__', '__module__', '__qualname__', '__dict__',...

Re: Viewing all class variables created within class instance
Without the brackets after ADC, you are not creating an instance of the class i.e. not calling the constructor. Your first attempt was correct, but you have to supply arguments (as the error says), sorry but I left that out in my sample because i don't know them by heart plus they might be different...

Re: Viewing all class variables created within class instance
Call dir() on your instance, not on the class itself. Like
Code: Select all
a = machine.ADC()
dir(a)
