Programmatic access to Audrey's "sleep" mode
Programmatic access to Audrey's "sleep" mode

New MessageProgrammatic access to Audrey's "sleep" mode (modified 0 times) johnhamm

This might be the wrong place to post it, but I don't think this is a QNX-related question since it has to do with Audrey hardware functions.

I want to write a slideshow app that puts the Audrey in sleep mode at midnight, then brings her out of sleep mode at 6am. I want to do this because it doesn't make any sense for Audrey to run at night. Is this possible, or is the only way to bring her out of sleep mode is to press a key or the screen?

Who would know the answer to this question? Do we have contact with any of Audrey's developers/designers?

You can use gpio to turn the screen on and off. I don't remeber the exact sytax, but you should be able to find it by doing a searh of this board.

Awesome, thanks guys!
I wonder if there is some kind of task scheduling program in QNX to run gpio at certain times with certain parameters so I don't need to have an external browser turn the screen on/off?

I wonder if you could accomplish this by creating 2 scripts, for example 1 called ScreenOn.sh and another ScreenOff.sh, each w/ the appropriate gpio call. I think you can get an idea of what gpio parameters to use if you look at this line in /kojak/go

#Switch display on!
/kojak/gpio -a 0x40010004 -b5 -m3 -s3

Don't know exactly what the parameters mean, but safe to guess that -a 0x40010004 is an address for some sort of hardware I/O port that controls the screen?

Then you could list ScreenOn.sh and ScreenOff.sh in the /config/kcrontab file to run at the appropriate times.

How's that sound?

Tried that.. doesn't seem to work. I've changed permissions on the .sh files either... I even tried doing a simple turn the LED to blink and that doesn't work.

Here's what I have:

/Kojak/ScreenOn.sh:
/kojak/gpio -a 0x40010004 -b6 -m3 -s3

/Kojak/ScreenOff.sh:
/kojak/gpio -a 0x40010004 -b6 -m3 -s0

/Kojak/LedBlink.sh:
SetLEDState 2

Tried chmod +x on the three files and a chmod 777 on them also.

They work when you run them under root, but not under kcrontab.

You might try execv app it allows you to execute .sh scripts like applications. It's worth a shot.

hey, folks . . . i once posted the results of # use gpio on another message thread about using the CF as storage. get the use command from QNX RTP, and you can find all the gpio options described...

kcrontab doesn't really seem to allow you to enter any arbitary programs, get cron from 6.0 or from my site

I've found that the GPIO option doesn't really put the audrey into sleep mode, it just turns off teh screen. to get out of the GPIO'd 'sleep' mode I need to hit the power button twice (once to power down and again to power up).

is there a better way to request sleep mode? perhaps throwing a 1 into the /config/SYSTEM_ScreenSaveSecs file?

Alex.

Seeing this old thread brought up again got me motivated to figure some stuff out. I can't keep my hands off of my poor Audrey! I went digging around in the kojak libraries and found a way to control sleep mode programmatically. Today I wrote a quick utility for it. Here it is. This really changes sleep mode, not just the screen backlight.

You can control sleep mode from the command line, or with kcron, or remotely from any web browser. You can also test the current status of sleep mode. It seems to work just fine, but I'd be happy to hear of any bugs. Note that turning off the screen via the command line requires a "sleep 1;" before the command, or else the key-up event causes it to instantly wake up again.

The utility and the source code are here. Note that it requires the libkojak.so library, which I think everyone still must have.

Jim this is great! just what I was looking for! I put the code into my picture frame app, and I'll be able to test it once I copy over libkojak.so to my qnx dev environment.

I'm intrigued by you mentioning you could run it from kcron, I never got any commands other than the defaults running from kcron and moved over cron and crontab from my QNX machine and that works fine.

I'll keep you posted on developments with this and ACID talking to palm DB's!

Sketchy can you explain how you got this working in kcron? I can not get it to work in cron or kcron. Thanks.

here is my cron setup.. for testing.. the date one is working fine every minute.
# crontab -l
#cron entries
* * * * * /nto/bin/date >/tmp/date.txt
* * * * * /nto/bin/screen t 2> /tmp/stat
#

I put the "2> /tmp/stat" at the end of the screen line to output errors to the /tmp/stat file. Here is what I see.
# cat /tmp/stat
Could not find library libkojak.so
#

Interesting.. I can run screen fine by its self. Any Idea's?

lalalala... set cron to run set and save output to a file.. here is what I see.

I see no "LD_LIBRARY_PATH"

I created a script that exports the LD_LIBRARY_PATH=/kojak:/proc/boot:/nto/lib:/nto/photon/lib:/nto/photon/dll:/real/plugins:/real/common
and then runs sceen 1 or screen 0 and it works now, but there must be a way to set this path for cron to automatically know the LD_LIBRARY_PATH. Anyone know how? Thanks.

Oops! I'm sorry, I never actually tested in in cron/kcron. I just assumed it would work. The cron commands appear to be running in an environment that is set up before all the kojak env. variables are set up. I haven't looked into it yet, but perhaps you should investigate where kcron gets launched, and export the right variables just before then.

Well I'm glad to see I'm not alone with cron. I'm having the same problems booya's having I've been diggin through to find where this stuff get set, but to no avail. The interesting thing is it happens when I run it from a PTERM where the environment variables are already established.

I think the file that setsup all the initial environment variables is /proc/boot/.script. But I don't think this is where cron is getting it's values. Has anybody found a way to edit the .script

By the way, I just had cron echo the variables to see if they were setup

I found this URL witch mentions the default Enviroment Variables and that if you need different variables you will have to set them from a shell script.

http://sdx1.uky.edu/cgi-bin/man.cgi?section=all&topic=crontab

I think I have screen working now in cron from a shell script that sets the enviroment and then runs screen 1 or 0. I have set cron for shutting off and turning on the screen at certain times. I will let you know if it works ok.. a side note is that the "date" line that bungee has in cron works flawless. Every minute I get a new entry.. I changed it slightly to overwrite date.txt rather than append though.

going on booya's script, I threw this together.

#!/nto/bin/sh
export PATH=/proc/boot:/nto/bin:/nto/photon/bin:/kojak:/nto/voyager/x86/bin:/real/bin:/tmp:/kojak/CGI:/kojak
export LD_LIBRARY_PATH=/kojak:/proc/boot:/nto/lib:/nto/photon/lib:/nto/photon/dll:/real/plugins:/real/common:/kojak
`"$@"`

save this as cronenv and chmod +x then when you want to run something in cron for example screen, just use 'cronenv screen t' This will setup the environment then execute the program

you can also solve the LD_LIBRARY path issue like this

echo $LD_LIBRARY_PATH >/kojak/ldpath.txt

and now in your crontab have something like this

5 * * * * LD_LIBRARY_PATH=`cat /kojak/ldpath.txt` commandToRun

works for me for starting my screensaver, and now I can make it turn the screen on and off

as usual you can get cron for audrey here

Bungee, I noticed on your page that you mention the "-" hyphen doesn't work in QNX cron but it does. A "-" then a "," doesn't work though. "0-5,23" Didn't work. I have noticed that the "/" doesn't work either.. "*/5" Didn't work. My crontab list is below.

0,5,10,15,20,25,30,35,40,45,50,55 0,1,2,3,4,5,23 * * * cronenv screen 0 1>/dev/null 2>>/tmp/err
Run screen 0 every 5 minutes from the hours of 11PM to the hours of 5:55AM

0,5,10,15,20,25,30,35,40,45,50,55 8-16 * * 1-5 cronenv screen 0 1>/dev/null 2>>/tmp/err
Run screen 0 every 5 minutes from the hours of 8AM to 4:55PM, Monday thru Friday

0 17 * * 1-5 cronenv screen 1 1>/dev/null 2>>/tmp/err
Run Screen 1 at 5PM on Monday thru Friday

0 6 * * * cronenv screen 1 1>/dev/null 2>>/tmp/err
Run Screen 1 at 6AM

Not to beat a dead horse since Davinci and Bungee came up with great work arounds, but....

This is probably what we need to do when running cron to start it with the proper enviroment.
