      Re: Unable to read SNES controller

      Hi there,

      I got my Controlblock in the mail totay and set everything up with the tutorial and it looks really exactly like the linked topic.
      Now i connected my SNES controller and when im trying to test it with

      jestest /dev/input/js0

      it is not working.

      I checked every connection and everything seems fine.
      But then i checked the power and there is the problem. It is allways 0V.

      Am I missing something obvious?

      Thanks for the help

        Did you install the correct driver version? Revision 2.* ControlBlocks need ControlBlockService2, rev. 1.* boards need driver ControlBlockService.

          yes I have Rev 2.1 and I installed controlblockservice2, but maybe I need to reinstall it because i downloaded controlblockservice (1) first but did not install it

            What does your meter say when you connect to the 5V source at the control block? (trying to determine if the controller isn't getting power, or if it's just not responding correctly, or something else with your wiring)

              Measured 5.24V on the Pins right next to the Mini USB Power Port where it is connected to the Power source.

                Because this happened to me: Are you sure the controller is good? With 25 year old hardware things can break. I was pulling my hair out trying to figure out why my setup wasn't working and then I plugged the controller into a known working Super Nintendo, and sure enough, the controller was broken. Tried another controller and all was well.

                  I tried both of my Controllers. They are working on my snes. I measured direktly on the controlblock Pins to avoid any wireing issues. But there are 0V too

                    @Jeddo So you're getting 0V at the control block pins? Can you either take a picture or make a diagram to show where you're measuring?

                      Yes exactly. I'm at work right now so I will take a picture as soon as I'm at home. But I measured between pin plyr1vcc and plyr1gnd SNES
                      To be precise the screws of the cable clamps

                        @Jeddo Diagnosing stuff like this over the Internet is tough, but some pictures will help a lot. We'll get this sorted, I'm sure.

                          @obsidianspider I'm at home now so I could take the requestet pictures. Here you go:

                          generell setup

                          Voltage on Player1Vcc to Ground

                          Voltage from GPIO Pin to ground

                            @Jeddo Based on this image from the website, it looks like you're hooked up to the wrong side. Try testing the pins on the bank directly across from where you're connected.

                              OMG that is embarrassing! Nice brain fart on my side. Switched the Pins and it works fine! Thanks for your help!

                                  @Jeddo no worries. I've done worse, sometimes resulting in fried parts. I'm glad it was something easy. Sometimes you just need another set of eyes to look at the problem.
