Web6 de abr. de 2013 · As it happens, I believe you're right on both counts, @AlexeyFrunze. I fiddled with the GPIO interrupt settings on my chip (documentation is horrible, and it appears that the clock on the debounce register actually serves as the master interrupt clock) and I can reliably hang the kernel when I hook up a high frequency signal :P In … WebThose can be delivered to the process as part of the timer interrupt. A sequence like this can occur: Process queues asynchronous I/O request . . . passage of time. Process is executing again. An interrupt occurs when the I/O request completes. The OS responds by queuing to the process. 4.Process is executing again. WebYou'd have to find a factorization that satisfies these constraints. Let's see an example, you'd want a 2.3 seconds delay. Note that 2.3s is the period, not the frequency, so you'd need to put its inverse into the formula. (PSC+1) * (ARR+1) = 84000000 / (1 / 2.3) = 84000000 * 2.3 = 193200000 chinese food riverview fl delivery

Web29 de nov. de 2013 · How long 100 ticks actually is depends on the frequency of the tick interrupt. You can convert ms into tick by dividing by the tick rate in ms, so 100ms is ( 100 / portTICKRATEMS ). If you set the frequency high then you can have a higher resolution time, at the expense of having to process more tick interrupt. WebSecond, you have to realize that there is additional overhead associated with a call to an interrupt vector.
