ram usage

I have been using mem_info() to look at memory usage, but that prints to the USB connection. Is there a way to access the same info from within my code?

You can try this:

Code: Select all

import io
import os

class DUP(io.IOBase):

    def __init__(self, s):
        self.s = s

    def write(self, data):
        self.s += data
        return len(data)

    def readinto(self, data):
        return 0

s = bytearray()
os.dupterm(DUP(s))
machine.info(1)
os.dupterm(None)

The main useful stats from micropython.mem_info() is the "GC: total: 2072832, used: 3264, free: 2069568" line.
You can get these three numbers using "gc.mem_alloc()" and "gc.mem_free()"

But if you want the other stats, then yeah the dupterm idea works nicely

Those 3 numbers are all I'm looking for. Thanks
