Interrupt Delay Question Mbed If i recall correctly and they haven't changed it back, the lpc1768 interruptin code can handle something like up to 400khz, so 2.5us delay. less than what you see, but it quite a bit. In general an incoming interrupt which is masked will leave its flag set, so a response can be made once the interrupt is enabled again. of course a delay in response has been introduced, and the latency much compromised.
Issue With Rising Edge Interrupt Delay In Nucleo F103rb Question Mbed This document provides an overview of using timers and interrupts in embedded systems using the mbed microcontroller. it discusses using timers to trigger scheduled tasks, using multiple timers to run tasks at different rates, using hardware interrupts to trigger tasks in response to external events, and techniques for debouncing switches to. Optimize interrupt handling in arm mbed os to reduce latency issues. a concise guide for firmware developers seeking efficient performance solutions. Simple example 2 • use pin d4 interrupt to increment a counter w debounce wait time • in the isr no interrupts possible. The main disadvantage of using interrupt is scalability – as more interrupts are added, so it becomes more challenging to follow the code, optimise the priorities and to guarantee that all device response times are always honoured.

Use the timeout interface to set up an interrupt to call a function after a specified delay. you can create any number of timeout objects, allowing multiple outstanding interrupts at the same time. This library enables you to use interrupt from hardware timers on an nrf52 based board using mbed rtos such as nano 33 ble. these nrf52 hardware timers, using interrupt, still work even if other functions are blocking. The mbed makes use of these in three distinct applications, the timer, used for simple timing applications, timeout, which calls a function after a pre determined delay, and ticker, which repeatedly calls a function, at a pre determined rate. As it is calculated based on the expected execution time of a software loop, it may well run slower than requested based on activity from other threads and interrupts.
