System Workbench for STM32


false condition if statement getting executed inside ISR

France

The simplest way to go, as you measure time between the last interrupt, is to just ignore any interrupt occuring less than x µs after a previous interrupt. Thus the first switch will be taken into account, then all bounce IRQs will be ignored waiting for at least x µs without any interrupt.

If you have ONLY one GPIO generating interrupts on the port where you connect the EXTI interrupt, then you may disable this IRQ in the NVIC, arm a timer for x µs, then re-enable teh EXIT interrupt in the NVIC when the timer expires; that is a bit more complex, but will cost less CPU cycles...
