Faced with having to buy a crystal to serve as master clock for a protocol that doesn't require a master clock, and then figure out how to get RPi to cooperate with the crystal, I've finally given up on making my own circuit for the TI DAC IC I purchased. Now I see that, while my budget is more limited than I like to admit, some of the premade cards I see people talking about aren't so bad price-wise.
But really, I just saw on this site that the Cirrus Logic Audio Card, one of the few I can find available at a semi-reasonable price for shipping to Romania, has been replaced with "a superior alternative - Pi-DAC+" that doesn't even have ADC? Am I the only Pi owner disappointed by that? I'm looking for high-quality audio, not an entertainment system. I.E., I'm a musician and a long-term Linux audio user.
Regardless, I have a question. Supposing I do choose to order one of these Cirrus Logic cards that are still around. Can I still use any of the Pi's other GPIO pins? As a Windows 95 user 20 years ago, I only needed 25 pins to run my peripherals, and if just an audio card covers up all 40 pins on a brand-new device, it seems like a big step backwards. Looking at the quasi-datasheet provided by Element 14, it appears that, yup, just the audio device uses almost all 40 IO pins.
Anyone have one? Any observations? Any other musicians still trying to make use of a Pi and interested in ADC?
