Worth noting that perhaps more interesting for integration, from a hardware perspective, is the Raspberry Pi Compute Module which is designed exactly for that.

yes the compute module was my intention. however, itā€™s annoying that the compute module is $40 whereas the zero is $5.

sadly those pwm outputs sound like absolute garbage.

Yeah. On an old Pi Iā€™m using as a streaming server, Iā€™m using a Wolfson audio card, but I doubt thereā€™s anything like that for the RPi Zero yet.

#26

hifiberry should work given the zero is pin-compatible with the pi2. not sure about the wolfson.

Iā€™m trying to find an eagle file (or something) for the terminal tedium pcb and having no luck. Iā€™m missing somethingā€¦

Perfect! Thank you very much.

@infovore thanks for the headsup on sonic pi! This looks amazing. So much so that Iā€™ll be using it with my afterschool club in the new year.

Also:

https://shop.pimoroni.com/products/phat-dac has been released in the same small format as the PiZero.

Iā€™ve really been enjoying watching livecoding videos. Itā€™s a self-documenting process. I learn so much every time.

I gather thereā€™s some lineage between Sonic Pi and Tidal, but Iā€™m very fuzzy on the evolution/history of these toolsā€¦

#33

oh, iiinteresting. I need an affordable DAC for a Pi, and that looks excellent.

#34

yeah, i got one of these the other day. not even had time to solder the header to it yet, but i have a couple of weeks off over christmas, so iā€™ll have a play and report back how it sounds.

pi zero is still out of stock everywhere though, so iā€™ll be using it on a pi2. my intention is to try hook up some midi controllers and run pd headless and configure pd patches to start on boot. hopefully. or iā€™ll just use it with a tv maybe.

ā€œ[ā€¦] the i2s is great (hifiberry sounds good, i have one) but thereā€™s lot of hacking to be done to get it working well (ie, supercollider without jack??)ā€

Before I get into this ā€“ Anyone can confirm jack is working now with I2S? (The Internet seems to suggest as much?)

ie

dtoverlay=i2s-mmap

#36

As of revision 2 of the Raspberry Pi, the i2s interface is exposed via gpio pins.

Looks like the kernel driver was merged into the source tree, too:

Also be aware that the driver needs to work with ALSA (will yield better results for you than ā€œJACKā€ in a google search).

#37

Sure. I was looking at the eurorack module linked above, which uses the i2s interface (it uses a codec). Itā€™s just that I didnā€™t find a lot of information on jack in the connection. Only mention of it being supported ā€œnowā€. But nothing on whether it actually works, or works well. Hence the question. (I missed out on the ā€œZeroā€ when it became available, so I have to wonder in the abstract ā€¦ )
