Buffer too small

[guykoy123]

I have created a task that has quite a few variables, it loads ok however as soon as i try to run it i get the following output:

Connecting to board COM3

Micropython version: 1.241
Framework version: 2.0.2

Transferring state machine Experiments - Two pumps\E1_2_pumps_behavioral_experiment to pyboard. OK

Run started at: 2025/04/08 16:33:34

484477:33:34.543	error		

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "pyControl/framework.py", line 175, in run
  File "pyControl/framework.py", line 91, in output_data
OverflowError: buffer too small

Error during framework run.

From what i understand it's trying to print the initial values of all the public variables but i guess the list is to long i my case.
Would love to hear if anyone has encountered something similar? Is there a fix?
I tried reading the framework.py code but didn't see a problem with it.

Hey @guykoy123, I ran into the exact same issue (described here) after upgrading to 1.24.

The fixes (cef428d and 145e97b) have been merged into the latest pyControl code.

If you are tracking pyControl with git, you can git pull the latest changes and that will fix the problem. Otherwise, you can delete your local copy of source/pyControl/hardware.py file and replace it with the latest hardware.py which you can download here. Do the same for source/pyControl/framework.py (download here)

also, you will need to load framework for the changes to transfer onto the microntroller
