Automate command lines that use rshell

[Alqx]

Hi the micropython community,
I encountered a problem using rshell . In fact, I am on windows 10 and I am using a batch file to automate command lines (4 lines in all). The 3 rd line involves the rshell. Only here, once I am correctly connected to the rshell, the last line is not carried out.
Do you know why ? If yes, how to fix it?
I leave you a screenshot attached.
Here are the command line:

d: #in order to connect to the correct disk
python CAMERA.py #run a python script using the webcam
rshell #in order to connect to the pyboard
repl ~ exec(open('motor.py').read()) ~ #run a script on the pyboard allowing to run motors

Thank you in advance for your help!

You should be putting the repl command on the same line as the rshell commnad. So:

Code: Select all

d: #in order to connect to the correct disk
python CAMERA.py #run a python script using the webcam
rshell repl "~ exec(open('motor.py').read()) ~"

Normally, I would use import rather than exec. i.e. use:

Code: Select all

rshell repl "~ import motor ~"

I'm not exactly sure about the quotes when using windows, but they're definitely need on Mac/Linux.

The way you've show things, rshell will be launched and once you press Control-D to exit, it will then resume running the script and probably produce an error because it doesn't know what the repl command is. For example, I created hello.py with the following contents:

Code: Select all

import time

print('Hello World')
print('Sleeping for 10 seconds')

time.sleep(10)

print('After sleep')

and running this shows:

Code: Select all

$ rshell 'repl ~ import hello ~'
