Interrupt based serial read using IRQ

  • I am working on building a system which gets data from serial port UART/USB. Implementation is python based.
    The issue I am facing is I don't want to use infinite while loop. I have seen implementation with select, multi thread and pyserial but i know pyserial internally using select and I am bit confused about the overall implementation.

    Another aspect I have looked into is using IRQs and I probed the file /proc/interrupts and found some IRQs for UART - 11 and USB - 3.

    My question is how to use them to make proper interrupt based serial communication.
