      @Dakota If DCS cannot put that line into event mode, that's usually an indicator that the given pin is either not accessible or it is still allocated by SysFS. You may need to unexport it before DSF can use it (see /sys/class/gpio, maybe you can achieve that by sending echo 2 | sudo tee /sys/class/gpio/unexport according to https://f1atb.fr/index.php/2022/01/20/orange-pi-gpio/).

        @chrishamm thank you for the reply!

        so my specific ability to edit and control the gpio pins is different as orangepi uses a fork of "wiringPi" called "wiringOP". From there I am able to unexport using:

        gpio unexport 13 out

        I am also able to change the mode and value using:

        gpio mode 13 in/out/pwn/clock/up/down/tri
gpio write 13 0/1

        where I get lost now is I have no idea what mode or value to change it to for DSF to be able to use it...

          @Dakota There are two sets of utilities for controlling GPIO pins, one is SysFS (which WiringPi and probably WiringOP use AFAIR) and the other one is gpiod (which DSF uses for performance reasons). The pin numbering is different depending on the subsystem used. You should use the gpioinfo utility from the gpiod utils instead of gpio readall which probably uses the wrong GPIO interface. Please make sure to follow https://github.com/Duet3D/DuetSoftwareFramework/wiki/SBC-Setup-Guide#link-between-the-duet-and-sbc as some extra steps are also required to get DSF to operate nicely on different SBCs.

            @Dakota 117 seems ok from the formula used by the sunxi driver : (position of letter in alphabet - 1) * 32 + pin number
            So in your case, the pin 22 is mapped to PD21 (See the image below but that is also wrote in your gpio readall output)
            as D is the 4th letter : (4-1) * 32 + 21 = 117.

            However, I believe the GPIO chip device /dev/gpiochip1 you are using is incorrect.
            gpioinfo which is provided by gpiod package may give you more clue about that.

              @Falcounet I tried using both chip0 and chip1 which didn't change the outcome...

              here is my list from running gpioinfo:

                  @chrishamm I was able to edit through the directories, however now I get an error saying access denied to /unexport. But after rebooting it returned to error code 19 and unable to connect.

                    @Falcounet well wait now I'm confused... when I look at the directory it lists chip0 and chip352... gpio info still lists chip0 and chip1.

                      @Dakota Look at chrisamm comment above about sysfs / gpiod
                      You can't use sysfs with DSF.

                        @Dakota What I did a while ago when I was faced the same issue is :

                        1. To feed 3.3V (or whatever voltage is safe for your GPIO pin to set it to TRUE state) on the pin number 22 on the connector
                        2. Run gpioget in a loop to all the pins and store the ones that reports 1
                        3. Connect the pin number 22 to GND
                        4. Run gpioget in a loop to all the pins again and store the ones that reports 0
                        5. Make an intersection on the results from #2 and 3#

                        If you are lucky, you get only one result but if not, it should reduce the number of potential candidates pins.

                        However, be careful because there is some pins driven by the system so they can get a random state when you poll them.
