You can get up to 11 output pins for PRU0 (most of which can also be used as input pins), and two dedicated input pins while still keeping the HDMI/LCD and eMMC functional. I have a spreadsheet with the PRU pins highlighted (along with a bunch of other pinmux information and details related to various CNC capes) in github: https://github.com/cdsteinkuehler/beaglebone-black-pinmux/blob/hal_pru_generic/pinmux.ods The PRU0 pins are highlighted purple (output) and cyan (input). -- Charles Steinkuehler [email protected] -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
