Following my statement in issue #284 that importing is not working and @pfalcon's reply that it is (apropos #282), I decided to write a simple test case to show my findings.

I am basing my test case on the assumption that an import call will look inside the following two folders on the micropython chip:

• /
• /SRC

Case 1

• Firstly, I have just downloaded and compiled the latest version of the code.
• I then created the following simple main.py file which I saved in the /SRC folder.

MAIN.PY v1

counter = 0

def addition(a,b):
    return a+b

if __name__ == "__main__":
    while True:
        print(counter)
        counter = addition(counter,1)
        pyb.delay(1000)

Using:
minicom -D /dev/ttyACM0

I see a nice, steady counter printout to the console 👍

Case 2

• I then created a second .py file which I also saved in the /SRC folder

test_module.py

def addition(a,b):
    return a+b

and modified main.py to look like this:
MAIN.PY v2

import test_module
#from test_module import addition

counter = 0

if __name__ == "__main__":
    while True:
        print(counter)
        counter = test_module.addition(counter,1)
        #counter = addition(counter,1)
        pyb.delay(1000)

which resulted in no compilation error and no counter printout to the minicom console 👎 .

From the commented out code you will see that I also tried the format
from <module_name> import <function>
and it also didn't work.

Am I not understanding something or is it just not working?
