What datasheets have been made available for the roboRIO? I don't really see anything of actual use here:
https://decibel.ni.com/content/docs/DOC-30419, mostly just marketing garbage. I'm guessing it's fairly similar to the myRIO, but I really don't want to bank on it. I'm interested in making custom circuits for the MXP expansion, but I don't know how fast stuff like the SPI bus can rx/tx data. Also, specifics about the ADCs and DACs would be of interest.
