[Addon] RuneUI GPIO: power on / off audio equipments
Tested on RPi3
for RuneAudio 0.3 and 0.4b

View code - GitHub
Try it - Demo

GPIO-connected relay module control for power on / off audio equipments.
(can be installed without relay module to play with interface)



Power on off audio equipments in sequence

up to 4 equipments(relays)
delay setting for each equipment(relay)
notification broadcast for on off

Idle timer power off

polling 'play' status every minute
idle time setting
notification last minute warning with countdown
reset on play or during warning

Integrated into existing RuneUI

GPIO (speaker icon) button on the left of top bar
change button icon and color on on / off
show button only when enable
setting in Menu > GPIO (local browser: right click > Fullscreen (exit) > click GPIO tab)
RPi pin numbering diagram included, show / hide on click
Can be used with USB PC Remote

Warning !

A relay module can be connected to GPIO, to see how it works, by anyone with basic skill.
Wrong connection may just damage your RPi. (only 5V)
Requires electrical skill and knowledge to connect these relays as power switches. (110V / 220V)
Electric shock can kill.

Install:
from Addons

When you try to install will receive this error.: "./install.sh: line 211: syntax error: unexpected end of file"
I can see the missing one "fi"

if ! grep -qs 'RuneUIe' /srv/http/app/templates/header.php; then
echo
echo '========================================================='
echo '"RuneUI Enhancement" not found.'
echo '========================================================='
echo
echo 'It must be installed first.'
echo
(( $disk == 1 )) && echo 'And disk space less than 300MB. Expand partition before install.'
echo
echo '---------------------------------------------------------'
echo
rm install.sh
exit
HERE is mising "fi"
if (( $disk == 1 )); then

Hello rern,

The GPIO's are HI when off and LO when on, is it possible to revers it?
I want HI is on and LO is off.

I have tried editing the python file but no succes

Thank for you help.

Sorry for responding way too late. Board notification somehow had never reached me.
That errors was fixed. Actually, there's no need to expand the partition any more. The latest install script should iron out most of the glitches.
Let me know if there's still any errors or questions.
Some feedback would be nice.

if you just want to substitute the 0 / 1, you may assign variables for them.

Code: Select all

HI = 0
LO = 1
# or
on = 0
off = 1


Hi,

just found out, that the installation of the enhanced interface breaks the setup menu on my 7" waveshare tft.
Any suggestions?

A screen image or more detail of the broken setup menu would be helpful.

"Broken setup menu" might not be the right expression.
What happens:
1. using a browser on my PC -> the setup menu icon reacts like a charm and all setup menu items are shown and are responsive
2. using my waveshare 7" tft all "active" touch and slide areas work as expected, but the menu icon shows no reaction when clicking on it. The display comes with a very high resolution. I reduced the resolution down to 800x600 or so and added some overscan pixels at the top and bottom screen to have a safe hit zone.
With the non-enhanced GUI everything works with that screen setup and, as said, your enhanced GUI works besides of the menu icon.

So I think my description gives you more information than a screenshot with a non-responsive menu icon

@rern:
Just re-installed GPIO enhancement.
The menu-item is still responding on my TFT display and GPIO is shown as submenu item.
But: when trying to use the GPIO setup submenu by clicking on the GPIO item -> no reaction on my TFT screen.

I repeated the action on my iPad: works flawlessly and I can switch GPIO on/off, modify values etc.
What I saw on the iPad: it opens a new tab, independend from the main screen.

This might be the problem with the waveshare 7" TFT -> it stays on the same screen. I think that the built in browser either has no tabs or it has to be activated in your script?

Hi Raimund,

The GPIO settings page now opens in the same window.

Now I will install the GPIO add-on and built it up with one or two relays (I have only one amp "behind" the DAC); will feed back when it works.

One or two relays seriously?
Unless you have to fit it in a limited space, it's just less than $3 for a 4 relays module.

rern

Yeah, I know the price and I own already a dozen of those relays (singles, doubles and quadros) -> mainly for some Arduino based projects.
But in my given case for RuneAudio I only need to switch the amp and the TFT screen which I want to power separately from the Raspi (this will stay powered all time to wake it up). Will see if I find some time today to get it done and feedback what happens.
