Argparse with 'mpremote run <xxx>.py arg1 arg2' : OK on unix port , no succcess with ESP32 port ; one trick ?

[picpic020960]

Bonjour ,
I write tool for dump I2C memory. First I test with unix port without I2C , with parameters and mpremote run vidage.py 400 ; 400 = bytes to dump . Works fine.
Then with ESP32 port and the same command , no effect.
I made wrong think but where ?
Some examples help me , thank's

PS: tryed 'input' : not better
Exaples found but for python , not micropython mpremote

Suppose you have a script "test.py" in the "/tmp" directory, as shown below:

import sys
print(sys.platform)
print(arg1, arg2, arg1+arg2)

Doing this in a terminal in the "/tmp" directory:

$ cd /tmp
$ mpremote u0 mount . exec "arg1=1; arg2=3" run test.py
Local directory . is mounted at /remote
esp32
1 3 4

will mount the current working directory ("/tmp"), set the arg1 and arg2 values using exec, load and run the "test.py" script from RAM on your esp32 board.

Another alternative, which I prefer is to create two scripts in e.g. "/tmp" directory:

# args.py
arg1=1
arg2=3

and

#test1.py
from args import *
import sys
print(sys.platform)
print(arg1, arg2, arg1+arg2)

Then, from a terminal in any directory on your PC, run the following:

$ mpremote u0 mount "/tmp" exec "import test1"
Local directory /tmp is mounted at /remote
esp32
1 3 4

Hope this helps.

Exec 'arg1=1...' is OK with no mount
Thank's

mpremote run doesn't pass command line arguments to the microcontroller board

So why argparse in micropython lib?

[shariltumin]

I do not know why, I never use it. Maybe it is just for the Unix port. I haven't seen "argparse" in the esp32 port. Maybe it makes no sense on any MCU since we go straight to REPL or run main.py if it exists.

argparse is regularly used on the Unix port, for instance it's a dependency of the command line interface to unittest used there.

The embedded ports don't have the sys.argv and related parts of command line arguments though.
