I already create a topic in RPI forums but because I’m planning to use Volumio for this project also will as here
I’m planning my next diy project for compact active speaker/soundbar with Rpi, dac and Touchscreen.
The speaker will be powered from the mains so there will have at least two power supply units (for an amplifier and for the Rpi).
Until now I have built two audio systems with built in Rpi A and Rpi zero both using I2s dacs.
This time I wish to add some touchscreen for possibility to use Volumio even without wifi access.
I don’t know if is doable but from the information I found on internet I think there is some hope
Rpi Zero W would the the best choice because of its small size.
The problem is that I’m not sure what will be the proper approach to connect the screen and the dac to the Rpi.
I found some topics in which people ask how to connect both touchscreen and I2s dac using GPIO and seems that is not possible.
Not necessarily to use I2s dac but I don’t have an experience with other solutions.
I would be very happy if someone shared experience with such configuration (Pi zero + dac +touchscreen) or similar solution.
