Hi Charles, P8_03 is used as gpmc_ad6 by the board. Free pins start at P8_07 ff.
You can find examples in the source code of libpruio <http://beagleboard.org/project/libpruio/> on how to use a PRUSS to do pinmuxing and how to change the state of an output pin (or read the state of input pins). You'll find code to change any pin there. (You don't need any sysfs operations nor device tree overlays - just an overlay that starts the PRUSS.) In your case it may be easier to start with the pins directly connected to the PRU registers R30 / R31 (which is faster and easier, since you don't need to access the GPIO devices). -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
