Hi Dave,
Thanks for the info and example Dave .I am new to gpio,Sorry for asking basics questions,I am trying to write interrupt handler for 1 sec, Below is gpio-events,Right now I am going through your code gpio-event-drv.c,My Question's are
1. How do I implement irq handler should be raised 1 sec
2. Does I need to consider the raising edge and falling edge
3. From the o/p Can I implement the 1 sec irq handler,Please Correct if I am wrong
./daveuser 156:b:2000
# cat /proc/gpio-event/pins
GPIO: 156 Edge: Both Debounce: 208 msec
./daveuser 156:f:2000
# cat /proc/gpio-event/pins
GPIO: 156 Edge: Falling Debounce: 208 msec
# ./daveuser 156:r:2000
# cat /proc/gpio-event/pins
GPIO: 156 Edge: Rising Debounce:
208 msec
Thanks once again,
