MicroPython supports interrupts. But on some platform, like ESP32, the callback is scheduled. Preemption is still used, but it adds some microseconds and the delay is a bit variable. So it will work for some things, like reacting to a interrupt from an I2C sensor etc, or button push. But probably not good enough for a high speed protocol (so better use peripherals for that, like RMT in ESP32). |
