Hello. The code I wrote with external interrupt does not work.
If I press the button with intervals shorter than 500ms, it should not detect these button bounces..
If I press the watch button for more than 500ms, I want it to detect it.
Even if I press the watch button for more than 500ms, the value of the button variable does not increase.
If I just write the code below, the button variable increases, but because of the button bounces, even though I want it to increase by +1, it increases like +5 to +10.
void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)
{
if (GPIO_Pin == GPIO_PIN_1)
{
Button++;
}
}
Why aren't my codes at the beginning of the message working?
