          @gazredtyke try this command instead

          sudo modprobe fbtft_device name=adafruit22

            @moosepr would it be adafruit28 as my tft is 2.8"?

              @gazredtyke I think it will be the 22. i cant see a 2.8 device listed on the driver wiki, in theory the 2.2, 2.4, and 2.8 inch screens are all identically internally, they just have different sized pixels

                  @gazredtyke I will have to get mine hooked up to a keyboard and see what I typed to get it going, it's been a while...

                          @moosepr can you show a diagram of which gpio pin layout you followed? Maybe that's the issue?

                            @gazredtyke the error seems to suggest that it doest like the options being passed into the fbtft device call. my command scroll back doesnt go far enough back to see my initial testing bits. I need to go back to a fresh install of retropie and follow it all from the beginning.

                            If my new 2.2" screens ever come from china, i will be setting up another pi and will detail the lot

                                  @moosepr I've got the same with the exception I don't have anything on miso as that one is for the sd card isn't it?

                                    @gazredtyke that is what it said in the original link I sent you, but I'm pretty sure I linked the pin on my screen. I squashed the wires so it's hard to follow which is which, but I do seem to remember filling most of that block of pins on the pi

                                      @moosepr so maybe if I wire the miso to the pi?

                                        @gazredtyke give it a go. I'm pretty sure the only pins that are shared between the screen and the SD card are the power ones (but I could be wrong)
