Performance issue in put/get #69

Open kif opened 5 years ago

Hi,

I am facing many problems to upload/download (large) files with mpfshell, while it looks better with the ampy tool from adafruit. I have the feeling mpfshell transfers all data in ascii while ampy does this binary but I am not completely sure about that. Can you confirm ? how difficult would it be to offer another transfer mode ?

Cheers, Jerome

Hello,
you are correct: https://github.com/wendlers/mpfshell/blob/master/mp/mpfexp.py#L268

I wonder what it would take to switch to binary mode, transfer and switch back. I'll have to look into how ampy does it.

As always, PRs welcome!

After some investigation, it seems that mpfshell already includes functions like read_until, enter_raw_repl, etc, but they aren't used. They should be.

For reference, this is how ampy does it: https://github.com/adafruit/ampy/blob/master/ampy/files.py#L204
