Description

I tried to use Micropython to do real-time tasks on the ESP32C3, but it doesn't support hard interrupts, I can't get the timestamp and Pin state of the IRQ event (why don't MPY give such important informations rather then a useless Pin object), and if I use timer for resampling, the time jitter of the timer event is too bad (also a soft interrupt), so I had to try to use native code mpy, but the RISCV architecture of ESP32C3 is not supported, and there is no way to do it without customizing the firmware. How can I get millisecond-level time processing accuracy?

Code Size

I'm not sure about the code size requirement for this feature, maybe it's less than several kilo-bytes.
