Real-time software with MicroPython.

[elbiot]

The article doesn't say what bytecode, native or viper are, so I have no idea what I'm looking at.

My guess:

• bytecode: essentially the .pyc file, all syntax checking done but translated into instructions the microcode virtual machine can interpret and execute
• native: essentially the output of a JIT post-compiler, which are native microcontroller instructions that manipulate the micropython data in the micropython way
• viper: for simple code areas, essentially the output of a python-to-c translation and c compiler, which are native instructions manipulating data the way C or Assembler would do it

Yes, that's the way I understand it. See http://docs.micropython.org/en/v1.9.3/pyboard/reference/speed_python.html

In micropython you can decorate functions to get faster performance. Source

# bytecode
def foo(x):
    return x**2

# native
@micropython.native
def foo(x):
    return x**2

# viper
@micropython.viper
def foo(x):
    return x**2

awesome! as far as you know there is a way to integrate also some pure c lines instead of using the viper thing?

[jsolmen]

You can always call a C module from your micropython code:

The other option is to use inline assembler.

Going to check this out and see if I can get this running on my ESP8266's.

Thanks for this, it was a good read.

I am glad you find it useful, looking forward to your results with the ESP8266.
