I'm having an issue with simultaneous channel changes on a homebrew ir
blaster. I've got two Dish network satellite boxes, programmed to
different IR codesets, being blasted with a set of parallel IR leds
running off a single serial port and LIRC instance. I have two separate
channel.pl scripts that change one box or another depending on which one
you need to change. Everything works great if the boxes are asked to
change at different times, but if myth has scheduled two programs at the
same start time, the main box changes fine, and the second box doesn't
change, or only gets one digit or so. Is there any setting in myth I
can set to delay calling the script or sleep command or something I can
add to the second channel.pl script to make it hold off for 3-4 seconds
so the first box can stop it's transmitting and the second one can then
transmit?
The channel.pl script I'm using follows:
#!/usr/bin/perl
# make sure to set this string to
# the corresponding remote in /etc/lircd.conf
$remote_name = "JVC_RAW_1";
sub change_channel {
my($channel_digit) = @_;
system ("irsend SEND_ONCE $remote_name $channel_digit");
sleep 1;
}
$channel=$ARGV[0];
sleep 1;
if (length($channel) > 3) {
change_channel(substr($channel,0,1));
change_channel(substr($channel,1,1));
change_channel(substr($channel,2,1));
change_channel(substr($channel,3,1));
} elsif (length($channel) > 2) {
change_channel(substr($channel,0,1));
change_channel(substr($channel,1,1));
change_channel(substr($channel,2,1));
} elsif (length($channel) > 1) {
change_channel(substr($channel,0,1));
change_channel(substr($channel,1,1));
} else {
change_channel(substr($channel,0,1));
}
system ("irsend SEND_ONCE $remote_name cancel");
