Output the time in an -rt message
Is there any way to have a live time output on the radiotext? (-rt) For example: -rt "This is Example FM, the time is --:--"
I think it works with
-rt "The time is $(date +%H:%M)"
on bash (default shell on raspbian), mksh and zsh, but if you use another shell it may not work correctly. For live time output use -ctl controlfile and write it with a command in this file.
See also "Changing PS, RT and TA at run-time" in README.md
It should look like this:
mkfifo pifm_pipe
sudo ./pi_fm_rds -ctl pifm_pipe sound.wav
in another terminal:
cat > pifm_pipe << EOF
RT The time is $(date +%H:%M)
EOF
(repeat the last step ever when you want an update of the time or use a while-loop (while sleep 60;do
cat > ... << EOF
...
EOF
done))
It works well but it doesn't change by itself.... I have a -ctl already but wish for the time to update itself without human intervention so basically, -rt "Station1 - The time is $time" and the time be changing automatically on the radiotext.... is that possible without making another -ctl? I have an sh scrip running it, it's contents is: `#!/bin/sh
FX='equalizer 100 50 -10 equalizer 5k 2k 0.5 compand 0.3,1 6:-70,-60,-20 -5 -65$ FREQ='107.0' CLOCK=$(date +%H:%M)
while [ 1 ] do sox -V3 -t mp3 http://playout-pc:8000/feed1 -t wav - $FX | ./pi_fm_rds -freq $FREQ -pi FFFF -ps "Station1" -ctl rds_ctl -rt "It's $CLOCK - You are listening to Station1" -audio - done `
It doesn't work in one script, you must run in another terminal this script:
#!/bin/sh
while sleep 60;do
cat > rds_ctl << EOF
RT $(date +%H:%M)
EOF
done
It updates your clock forever all 60 seconds.
