[Question] limitations of Python script

Question

Hi, I’m interested in getting an EuroPi but I have some questions about it. In particular:

  1. is there a size limit for a Python script to be suitable for EuroPi?
  2. must the whole Python script be written as a single file or can it use local modules and packages?
  3. can the script make use of locally saved files, e.g. a .csv file?
  4. does it support scripts that use Python's Standard Library?

Many thanks in advance!

  1. is there a size limit for a Python script to be suitable for EuroPi?

The Pico has 264kB of SRAM, and 2MB of on-board flash memory, however Micropython leaves you with about 1MB flash memory. The EuroPi + ssd1306 libraries takes about 30k, so those are your memory constraints.

  1. must the whole Python script be written as a single file or can it use local modules and packages?

The firmware uses MicroPython which behaves just like Python and allows importing of packages.

  1. can the script make use of locally saved files, e.g. a .csv file?

Yep! We use this functionality in our Save/Load State functionality [docs | code]

does it support scripts that use Python's Standard Library?

Yes, anything that MicroPython supports can be used in your script.

MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimised to run on microcontrollers and in constrained environments.

I would suggest taking a look at the user contributed scripts to get a sense of what can be done with the EuroPi: https://github.com/Allen-Synthesis/EuroPi/tree/main/software/contrib
