Screen Switch-off / switch-on command executed 60*60 times #61

current software executes the command to switch-off or -on the backlight every second for a full hour which depending on the style how the switch is done might lead to strange effects. It fills the log file as well.

btw, the executed tvservice command does not seem to work with the raspberry pi foundation touch screen (not a hdmi device). As i'm not familiar with python (yet) I worked around by using a crontab for this. Maybe this could be integrated into the code also:

pi@teleframe:~/TeleFrame $ cat /etc/cron.d/display-onoff
# 0700 - on, 2300 - off
00  7 * * * root echo 0 >/sys/devices/platform/rpi_backlight/backlight/rpi_backlight/bl_power
00 23 * * * root echo 1 >/sys/devices/platform/rpi_backlight/backlight/rpi_backlight/bl_power

Might not be possible easily because the file is writeable by root only by default. Maybe there is some other way I do not know about.

EDIT: Just found this ;-) Thank you.
