Aug 24 10:37:04 <cityoflights2> av500: hi
Aug 24 10:37:15 <cityoflights2> is anyone here on a sunday?
Aug 24 10:38:15 <cityoflights2> well , after trying to google a solution fro the water flow sensor online, I wrote my own
Aug 24 10:38:20 <cityoflights2> http://pastebin.com/v9FyXRNY
Aug 24 10:38:41 <cityoflights2> I am hoping someone here may take a look, and comment on it
Aug 24 10:39:36 <hitlin37> ah...cool, your doing in python....so , is it working or not working?
Aug 24 10:40:23 <cityoflights2> it is, problem is to tell apart false pulses from real once
Aug 24 10:40:39 <cityoflights2> I think of it as a button debouce
Aug 24 10:40:55 <cityoflights2> when I press a button I expect to get bounces
Aug 24 10:41:07 <cityoflights2> If I only get a single pulse - its false
Aug 24 10:42:02 <cityoflights2> yet I may get many bounces when I open the tap and water start flowing
Aug 24 10:43:01 <hitlin37> real ones alwsy have two press?
Aug 24 10:43:25 <cityoflights2> real onces have at least two press
Aug 24 10:43:55 <cityoflights2> I was trying it with three, but noticed in some rare cases - it is not enougth
Aug 24 10:44:21 <cityoflights2> I also need to post this as, I didn;t see anyone do it
Aug 24 10:44:26 <hitlin37> you should add a comment at if rawState == ON  and OFF, its not obvious to me what it means
Aug 24 10:44:34 <cityoflights2> and it makes sense ...
Aug 24 10:44:43 <cityoflights2> thanks
Aug 24 10:45:53 <hitlin37> actually your innrer if code, its too nested with some many if, elif, if...
Aug 24 10:46:30 <hitlin37> i would say, if you can keep things within that whole while block to a bit simpler, it would be easier for you to debug
Aug 24 10:47:45 <hitlin37> in general, one level deep nesting is usually fine but too deep makes it difficult to debug
Aug 24 10:47:47 <cityoflights2> right, I need to look in to this,
Aug 24 10:49:56 <hitlin37> cityoflights2: for example, this one shows one way of doing debounce in python
Aug 24 10:49:57 <hitlin37> https://stackoverflow.com/questions/6578431/debouncing-joystick-button-input
Aug 24 10:50:50 <hitlin37> you can see it maintains one level deep loop, so its easy to follow the logic.
Aug 24 10:51:04 <cityoflights2> yep, but I am looking to use interrupts and therefor epool
Aug 24 10:52:25 <hitlin37> hmmm....try to see if you are doing everything ok within that while loop...make sure that logic is correct ....
Aug 24 10:53:36 <hitlin37> i usually draw such nesting on paper, its easier to follow....
Aug 24 10:57:41 <cityoflights2> hitlin37, as I am at work now, I will post a nicer version tomorrow.
Aug 24 10:57:58 <cityoflights2> I guess I don't need the  elif rawState == OFF and ( ( now - first_bounce_timestamp ) >= PRESS_MSEC ) :
Aug 24 10:58:37 <cityoflights2> I mean , as long as I output the debounce valuve, I don't need to reset the counter.
Aug 24 12:59:25 <suger> OK Noob question but ridiculously hard to find the answer online... How to display a .jpg file on the bone (original version), connected to the LCD7 cape?
Aug 24 13:11:02 <suger> I know the Beagle is intended for a more advanced user group but it is strange that this is so difficult for such a simple task. I just installed Raspian on the pi, with zero linux experience, and had images and video files playing within seconds. A task a have spent hours trying to accomplish on the bone. A shame cuz seems like a really interesting platform but support for entry level is nill.

Aug 24 13:34:06 <cityoflights2> cleaner
Aug 24 14:01:59 <cityoflights2> well , I am guessing most users here are napping, as it is a sunday
Aug 24 14:02:49 <cityoflights2> In case anyone is here, please see this python code, to debounce a water flow sensor
Aug 24 16:02:41 <Guest61079> does anybody have any experience in speeding up OpenCV using NEON in BeagleBone Black?
Aug 25 01:01:04 <router> hi
Aug 25 01:04:17 <router> is there a router operating system for the bbv
Aug 25 01:05:07 <veremit> roll ya own .. iptables is in debian repo :P~
Aug 25 01:08:36 <router> I want to use the bbb as WiFi repeater
Aug 25 01:08:51 <router> why isn't opewrt or ddwrt supported
Aug 25 01:09:08 <veremit> I'm not aware openwrt is still bein developed actively
Aug 25 01:09:12 <honestly> ask openwrt or ddwrt about that
Aug 25 01:10:11 <router> the pi is supported
Aug 25 01:10:31 <veremit> the pi doesn't have wifi does it?!
Aug 25 01:11:09 <router> neither does the bbb. you use a dongle
Aug 25 01:11:31 <veremit> good point
Aug 25 02:50:51 <AquaZ> It seems impossible to uninstall ANYTHING from the BeagleBone Black. Has anybody managed to do this? For instance, Apache2 is installed but it can't be removed.
Aug 25 02:52:03 <wmat> AquaZ: what distro?
Aug 25 02:52:14 <AquaZ> Debian.
Aug 25 02:53:03 <wmat> http://xmodulo.com/2013/02/how-to-uninstall-and-remove-apache2-on-ubuntu-debian.html
Aug 25 02:53:22 <wmat> there's a few ways, but htat's one
Aug 25 02:53:53 <AquaZ> Ok thanks. I'll read and give it a shot.
Aug 25 02:54:13 <AquaZ> Oh.. I've been there and done that.
Aug 25 02:55:14 <AquaZ> It appears to uninstall and then when I reboot, it's back.
Aug 25 02:55:47 <wmat> try purging it
Aug 25 02:56:28 <wmat> sudo apt-get purge apache2 apache2-utils apache2.2-bin apache2-common
Aug 25 02:56:38 <AquaZ> root@debian-home:/opt# apt-get purge apache2 Reading package lists... Done Building dependency tree        Reading state information... Done Package 'apache2' is not installed, so not removed 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Aug 25 02:56:53 <AquaZ> Says it's not installed but it's running.
Aug 25 02:57:19 <wmat> you're on the BBB right, and not your host?
Aug 25 02:57:27 <AquaZ> Of course.
Aug 25 02:57:57 <wmat> hmmmm
Aug 25 02:58:35 <wmat> sdcard?
Aug 25 02:59:03 <AquaZ> No SD Card installed.
Aug 25 02:59:28 <AquaZ> This is like twilight zone stuff.
Aug 25 02:59:36 <wmat> sudo rm -rf /etc/apache2
