033 DON'T LET MICROPYTHON'S GARBAGE COLLECTOR RUIN YOUR PROGRAM

Рет қаралды 429

Like most high-level languages, there needs to be a feature to clean up the mess programmers leave. In low level languages the program is required to clear up unused variables, pointers etc. Micropython's device to automatically do this is called the Garbage Collector. It works great, BUT, it takes time to execute and it can cause intermittent pauses in your program. In this video, we cover this problem in detail with a very real and practical problem and solution.

Is 033 source code posted? Didn't see it on the bottom of the list.

Micropython's garbage collector loses track of stuff and leaves tiny bits of garbage distributed throughout RAM. You can call gc.collect() all you want. Soon you can't allocate a one kilobyte array even if you've got 90% free memory.

Thanks for the additional information! I have not run into anything like that - YET, but I suspect that problem is "just around the corner"! Cheers! Chris

Have you got any evidence of that? We've run simulated *years* of testing (actually performed over a couple of months) on some medical devices and have not seen this occur. Of course, we watched what the allocations looked like to ensure we weren't fragmenting memory...MicroPython never lost track of anything but it can - like any GC - fragment.
