hello everyone

today I have a problem but I don't have any solution for that

my problem: with USB per 1(ms) send 1 interrupt to system and if not solve this interrupt, the data will be broken

with freeRTOS if the Systick is 1(ms) the overhead will be high and it not good, I want to increase Systick be 10(ms), but if I do like that, that's not compatible with USB.

How can I solve this problem? (I really want to keep the Systick is 10(ms))

(My skill English is not good, if you want more clearly or information, I will provide)

Thank and regard!

hi Jack Peacock

I will make it more clearly

My teacher is sure with usb, 1(ms) it send 1 interrupt (I want to know it right or wrong?)

with usb, 1(ms) it send 1 interrupt for do somethings, and current task is being performing have to stop, but the time for switch context is 10(ms). how can I solve it?

thank!
