Hi
I need a little amp and speaker attached to a PI for an alarm clock project. The Pirate Audio Speaker looks ideal, but I don’t want the display.
Anyone know if it’s possible to run it with the built-in display disabled (or indeed never enabled)?
thanks!
Yes, the backlight will be on when it has power but it only displays info if you tell it too.
All you need to do to get the speaker / amp running is a config.txt edit
sudo nano /boot/config.txt
and add
dtoverlay=hifiberry-dac
gpio=25=op,dh
dtparam=audio=off
I have one on my itty bitty beat box, and all im’m using is the amp / speaker and the buttons. I did install the display driver, but its not currently in use, all I see is the backlight lite up.
Hi
thanks for the info. Do you know if there is any way to turn off the backlight? This project is an alarm clock in a bedroom so I don’t really want any light at all when the sound is not playing.
If you pull GPIO 13 low the backlight should turn off.
