# mbed-memtrace-logger
Analyzes and logs the memtrace output from mbed-os in a readable form.
This code is left over for the use with micro:bit and Calliope mini.
If you look for the original memtrace, check out the mbed-cli.
> You need to enable heap debug output!
Run with: `python3 memtrace.py /dev/cu.XXXXX 115200`
The script auto-resets the counts and output looks like:
```
