guys, i want to know how to create interrupt using timer in stm32f407 board
Have you considered looking in the stm32f407 documentation ?
It has nothing to do with Keil.
i didnot mentioned keil dude
But you are posting on the Keil forum, dude:
"The Keil Discussion Forum is an open forum where you may post questions and comments about Keil products."
