hi to all i do a project with st32f429 which calculate the time and when i press on the button PA0 it stop calculte and print the result on the lcd of stm32f429 , i do this project with EXTI but the problem is that i want to take the 100 first times in a table (tab[100]) in the main() but i cant because i do the project with interruption so is there any solution to take the 100 first time in a table else i want to detect rising edge without an interruption is there a method which did that ?????
Not sure why any of that would preclude the use of interrupts.
Perhaps you can spin in your main() loop reading the state of the GPIO pin, and wait for it to change state. ie was low, now high, do something..
