we successfully connected the SPI port using CS0 on the roborio to the SPI connection on the navx board. no connections via the mxp ports. we used the +5V pin on the roborio SPI port to power the navx. everything seems to work according to the DataMonitor java test.
one thing to note, in a previous post you had indicated that we needed to connect MOSI to MISO, that is NOT the case. when i tried that, no data. connecting MOSI to MOSI and MISO to MISO worked.
i know you had indicated using the USB for power, but both of our USB ports on the roborio are being used. it seems to do fine with the +5 pin from the SPI port. when does a roborio stage 2 brownout occur?

thanks for your help.
