Hello,
i've got a question.
i have a module with an interrupt line connected to a fifo
what does this mean, please explain more.
It means when receiving an interrupt a fifo is filled with data and it
takes some time until the fifo is full.
when i start reading the fifo right away, i would read the fifo faster
then the fifo is filled so there has to
be a delay of around 400 uS..
is it possible to wait after an interrupt for 400 uS before execution a
function (reading the fifo)?
why you want to wait in interrupt handler, not a good idea atall.
I dont want to wait in an interrupt handler, i just want to delay
reading the fifo because otherwise the fifo won't be filled yet.
I know there are bottom halves to delay execution of a specific
function, but those are always in the range of jiffies, not micro seconds.
