CAN BUS - is the CAN.rxcallback() delayed by the GC?

Post by beyonlo » Thu Jun 09, 2022 8:06 pm

Hi all.

I would like to use the Pyboard D-Series (SF2W model) for realtime communication using CANBUS, and I would like to know what is the behaviour of the pyb.CAN.rxcallback() (https://docs.micropython.org/en/latest/ ... rxcallback) when Garbage Collector (GC) is running. Will the CAN.rxcallback() delayed by the GC, or the CAN.rxcallback() will interrupt the GC?

Thank you very much
