Trying too understand correct pins for DAC1/SCK and DAC2/SSN? on P1. @BDub can you help?
I see the following:
Spark.lbr shows the following. These are my guesses as to which one is DAC1 and DAC2.
These 2 pins look reversed in “https://raw.githubusercontent.com/spark/photon/master/pin-mapping/photon-pinmap.png”

Right! That’s just a coincidence that they are 22 and 24. The PØ is a different module than the P1 and just happens to have DAC1 and DAC2 on similar pin numbers 
So your schematic view is flipped, DAC1 would be pin 24 of the P1, and DAC2 is pin 22 of the P1.
Thank you @BDub! I thought the only difference between P0 and P1 was the PCB antenna. If that is not the case, am I missing a more recent update for P1 pin mapping than this? https://github.com/spark/photon/blob/master/pin-mapping/p1-pinmap.xlsx
I’m questioning other pins now such as SPI3 interface, which I copied from the P0 pinmapping.
Just like the Photon, I actually have a whole datasheet written for the PØ and P1. Just need to finish up some of the images before release. In fact, I need to update some as well or I would post the pinout images here tentatively.
Looking forward to it @BDub. Hoping to have PCBs ready to receive P1’s by the time they get here.
It would be awesome to have the P1 datasheet pinned up so its readily accessible. Thanks for this!
