MemoryError: memory allocation failed, allocating %u bytes

[MorseIot]

When you try to run file (test.py) with size of 18447 bytes, the error is generated:

Code: Select all

MemoryError: memory allocation failed, allocating %u bytes

When I split the same, it runs correctly. Is there any limitation of file size (py), or command that can bypass this situation

I suggest you read this part of the docs.

Thanks Peter Hinch, iam read the doc.

I need help using mpy-cross or use frozen bytecode

[pythoncoder]

To use frozen bytecode you need to be able to build the firmware. Instructions are here. Once you can successfully build and flash a firmware build, freezing bytecode is done by putting your Python source in ports/esp8266/modules/, building and flashing.
Issuing

Code: Select all

>>> help('modules')

will list modules successfully frozen.

Ok

Just in case you use Windows, I keep a version of mpy-cross.exe here: https://github.com/robert-hh/Shared-Stuff
