Hey there! Just wondering if it’s possible to combine something like the HiFiBerry DAC with the Hyperpixel 4.0 touch? It looks like the HFB can be connected to an additional set of header pins, would this work? I’d like to build something like the RPi Hi End Audio DAC seen here
Thanks!
That additional header pin on the Hyperpixel is for i2c. I think you’ll find that your DAC uses i2s. If it does the two are not going to work together.
Thanks @alphanumeric
I’m kind of a noob and don’t really know what the i2c is, however, this article says that you can use i2C devices with the HP4.0 if you symlink it.

Does that mean I could potentially use a DAC if I rig up one of those connectors?
If it used i2c yes. Most DAC’s use i2s though. You need a pinout of what pins that Hat uses and what functions they do.
I²C (Inter-Integrated Circuit), pronounced I-squared-C, is a synchronous, multi-master, multi-slave, packet switched, single-ended, serial computer bus invented in 1982 by Philips Semiconductor (now NXP Semiconductors). It is widely used for attaching lower-speed peripheral ICs to processors and microcontrollers in short-distance, intra-board communication. Alternatively I²C is spelled I2C (pronounced I-two-C) or IIC (pronounced I-I-C).

I²S (Inter-IC Sound), pronounced eye-squared-ess, is an electrical serial bus interface standard used for connecting digital audio devices together. It is used to communicate PCM audio data between integrated circuits in an electronic device. The I²S bus separates clock and serial data signals, resulting in simpler receivers than those required for asynchronous communications systems that need to recover the clock from the data stream. Alternatively I²S is spelled I2S (pronounced eye-two-ess) or ...
Normally I go here to see what uses what pins. Your HiFi Berry DAC isn’t in the list though
