In the pru, R31 is for input, so in that table you're looking for pin "pr1_pru1_pru_r31_8". That's on P8.27, which is used by the HDMI framer. If you *need* to use this pin, instructions on disabling the hdmi framer can be found by searching this group.
Of course you'll have to enable the receiver, otherwise the state of the pin couldn't be measured! Also, here's a easier to digest table for the pru header pins: https://docs.google.com/spreadsheet/ccc?key=0As0aJokrBccAdGkxeHkyYW1qRHNQdm5yZDhPQlRNR2c#gid=0 On Tue, Jan 21, 2014 at 6:08 PM, Christopher Hopwood < rockybulwin...@gmail.com> wrote: > I need to make sure I'm understanding correctly.
