How do you balance interrupt latency and power consumption in low-power embedded devices?
Low-power embedded devices often need to handle interrupts from various sources, such as sensors, timers, or communication interfaces. Interrupts are events that trigger the device to stop its current task and execute a specific function, called an interrupt service routine (ISR). However, interrupts also have a trade-off between latency and power consumption. Latency is the time it takes for the device to respond to an interrupt, while power consumption is the amount of energy the device uses to process the interrupt. How do you balance these two factors in your embedded software programming? Here are some tips and techniques to help you optimize your interrupt handling.
