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, Best Regards, --- On Thu, 2/12/10, Dave Hylands <dhyla...@gmail.com> wrote: From: Dave Hylands <dhyla...@gmail.com> Subject: Re: gpio rising edge To: "Hemanth Kumar" <hemw...@yahoo.co.in> Cc: kernelnewbies@nl.linux.org Date: Thursday, 2 December, 2010, 12:23 PM Hi guys, On Wed, Dec 1, 2010 at 9:30 PM, Hemanth Kumar <hemw...@yahoo.co.in> wrote: > > Hi All, > I tried with gpio-event > from http://svn.hylands.org/linux/gpio-event/module/gpio-event-drv.c which is > provide by Dave Hylands , it gives me the put > ./daveuser 156:b:2000 > # cat /proc/gpio-event/pins > GPIO: 156 Edge: Both Debounce: 208 msec There is some documentation on how to use the code, and how the code works, over here: <http://www.gumstix.net/wiki/index.php?title=GPIO_Event_Driver> And if you have any questions, feel free to ask. -- Dave Hylands Shuswap, BC, Canada http://www.DaveHylands.com/ -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecar...@nl.linux.org Please read the FAQ at http://kernelnewbies.org/FAQ
