[casper] I2C and SPI on roach {I,II}

HI all. We have a need for an I2C *or* an SPI port on ROACH 1 and 2. There are actual headers on R1 that say "SPI" and "IIC". Are these attached to the PPC? Is there any driver support for them? On R2, these ports are not obviously present. I suppose the GPIO pins connected to the PPC could b

Thanks, David. What voltage levels are on the IIC bus on R and R2? John > Hi John. > >> We have a need for an I2C *or* an SPI port on ROACH 1 and 2. There are >> actual headers on R1 that say "SPI" and "IIC". Are these attached to >> the >> PPC? Is there any driver support for them? > > Thes
