Hi Guys,
I'm using LMS since a certain while. While I got some devices, one is a PiCoreplayer connected to the AUX input of my bathroom radio. (GIRA in-wall radio). Now I'd like to put everything under the wall and remove the GIRA radio. I got a Pi Zero W with a Hifiberry mini-amp, which will connect to the small ceiling-speakers. I also added a 1.3" OLED I2C display, which works great. The next thing I'd like to add are TTP223 touch-buttons for play, pause, vol+, vol-... etc. The PiCore uses SBPD (SqueezeButtonPi) for controlling. After I soldered one of the buttons and made a little breadboard-connection to test it, it is working worse than "so-so". What happens is, when the TP223 is connected to power, the music will not come out of the speaker (even when it is playing, what I can see on the display!). I've figured out that the TP223 button is bridging GND & the I/O-port when connected to power. When "touching" the button between GND & I/O, there is 2-4V. (depending on the VCC). So in fact, the music "mutes" (not like a mute via any command, but as if you'd cut of the power of the amp) when for e.g. BCM16 or BCM26 are connected to GND. After it is disconnected, the music immediately is hearable. Also when the button is pressed - then there is no connection between I/O & GND. The BCM16/26 (the ones I tried) are not used for the hifiberry, so this can not be the source of my problem. Any suggestions?
