toute mes excuses , mon anglais date de tres loin
je voulais dire que mon programme chauf.mpy contient une boucle ' while true ' et que , quand je fais ' import chauf ' rien ne se passait

mais maintenant ça va mieux , il faut que je debug toutes mes erreurs de programmation , car je ne pouvais pas le faire avec chauf.py vu que j'avais un probleme de sram
merci

(response in English for other readers)

It is normal that nothing happens after the first time when using import because the module is cached. In order to run it several times, do

Code: Select all

del sys.modules['chauf']
in between to clear the cache (import sys if needed).

If you have both chauf.py and chauf.mpy in your filesystem, as explained here, .py will be used in preference and may cause a MemoryError if it’s too large to compile. So make sure you only have the .mpy.
