Memory Allocation Issue with Code for OV2640

[cole-morrel]

Hello, I'm trying to get an OV2640 Arducam I bought working with my ESP32 and I found this code that I thought would work. However, whenever I try to run the code I get this error:

Traceback (most recent call last):
File "main.py", line 28, in
File "main.py", line 15, in main
File "ov2640.py", line 79, in capture_to_file
File "ov2640.py", line 105, in appendbuf
MemoryError: memory allocation failed, allocating 252 byte

The ov2640.py file in question is this.

My installation of Micropython is completely clean, and other than the rest of the necessary files for the camera code I have nothing on the ESP32's memory. I'm a little confused by what exactly is causing this issue and how I might go about fixing it.

Thank you for the help.

Could be similar to an error I was getting with another camera distro. Have you tried a power on reset, ie the EN button?

Yes, unfortunately when I press it it still gives me the error

I got a buffer protocol required error just thought it might be similar.

Good luck.
