Web27 sep. 2024 · Interrupt driven I/O is an alternative scheme dealing with I/O. Interrupt I/O is a way of controlling input/output activity whereby a peripheral or terminal that needs to make or receive a data transfer sends a signal. This will cause a program interrupt to be set. Web4 okt. 2024 · So the only thing that your interrupt could possibly ever interrupt is the next line after the readString command which is the section that you want to put in the interrupt. If you think about the overhead of an interrupt vs just letting the code hit that next line, the interrupt would actually make your code slower and add more lag. – A software interrupt is requested by the processor itself upon executing particular instructions or when certain conditions are met.
