      It seems I had an error in one of the commands, it should be working now, the repository was updated for both 166 and 200KHz versions.

        I can confirm: the new version of your gamecon driver delivers force feedback using both motors. Great! But the 200 kHz version produces ghost input after a few minutes. I'm going to test the 166 kHz version now.

          Tested the 166 kHz version for about four hours - no ghost input so far. Wonder why force feedback makes the 200 kHz version more susceptible for ghost input.

            The problem is that I've made more changes in the driver between those two releases, so I might have done something that damaged the timing. I will investigate... in the meantime, do You still have the original .deb that didn't have the random input issue, but had small motor rumble missing? I might need it...

              A few minutes of actual gaming and I had ghost input even with the 166 kHz version - mostly "Start" and "Select". Also rumble is very weak on my controller, but I already identified the lines in the source where I might be able to change that (thanks to your code commentary).

              I still have the driver version with only the big motor working. I'll be happy to provide it to you.

                That would be nice, upload it for me please, cos I don't do any subversion, which is probably a mistake :D I will try to diff it with the current version and see whats the problem...

                  You find the old version of the gamecon driver here: MegaNZ

                    The link does nothing... you need to right-click the file and choose "Get link"

                        Thanks.

                        So that 2.0 200KHz in the archive was working well for you, in terms of random input?

                          Yes it was. Tested for about 12 hours in Emulationstation (with the game menu open, were a random button press would bring up the menu or start a game) an for various, although short game sessions (were the current driver resets the game or exits RetroArch after just a few minutes because "Start" or "Select" are erroneously detected).

                            When I get home from work I will look into it... in the meantime, try the older working version if You happen to encounter any random inputs

                              Well, the changes are only marginal to be honest...

                              But I might be up to something. I've managed to find this web on the WebArchive

                              http://web.archive.org/web/20090228013235/http://www.geocities.com/digitan000/Hardware/22/e22_page.html

                              This guy puts quite significant delays between bytes - 60us! Thats less than what he used when transmitting/receiving bits - 100us (thats just 10KHz clock). Current driver has only 25us as gap between bytes, not speaking of clock (5-6us). I will try to experiment with it, I've set the clock to 7us (142KHz) and delay between bytes to 12 clocks (12*7).

                              I have updated the repository (2.0 142KHz) and I've also included new "SDK" for 2.0, the scripts have changed a bit. Simply edit/overwrite the .c file that is in the directory and run sudo ./do.sh - it will unpack the package, update the .c file, calculate new MD5 hashes, pack it together and install.

                                Still random input...

                                What I am testing now is to read the data not straight when the clock edge goes up, but after a half-clock interval. I hope this will finally work, I am leaving it running as I am off to work

                                  I've uploaded an 8us version of driver that so far has not caused much trouble. Try it

                                    I've implemented a safety feature from Katemonster's code

                                    https://www.dropbox.com/s/ejdwtkjovr8ue9m/gamecon_gpio_rpi.c?dl=0

                                    detecting random SELECT pushes. Adds a bit of delay to Select press, but should eliminate random input once for all. I've also increased frequency back to 5us, testing now...

                                      Back after a long time!

                                      I have the final version of the driver, updated also for running on the new 4.9 kernel, no random input.

                                      Enjoy!

                                        this thread answers a few questions from my side about the usage of force-feedback/vibration at the psone/ps2 controllers.
                                        @Jofo: a BIG thank you for your work here !

                                        but I'm sorry for such a dull question now (I'm a NewPie in linux-stuff, but an old-timer in hw-stuff):
                                        how do I install the gamecon-gpio-rpi-dkms_2.0_all.deb driver now?
                                        guess I can't use the RetroPie-Setup Script (because this will only look at the drivers found @ www.niksula.hut.fi/~mhiienka/Rpi).

                                        is there a way to copy the debian file to the raspberry and install it from there via command line ?

                                        Dem Inscheniör is' nix zu schwör...

                                          Hello Jeff,
                                          in order to install the driver, run (once copied on your RsPi):

                                          sudo dpkg -i gamecon-gpio-rpi-dkms_2.0_all.deb

                                          Configuration is the same as for the original gamecon driver, so check the documentation. I plan to make a page about the driver, the wiring and so on, if any questions - write here for now ;)

                                          Hope it will work on Your setup :)

                                            guess I'm a good guinea pig to bring up all the NewPie questions for your page ;-), at least from the software point of view.

                                            first question: to which folder do I need to copy the *.deb file ?
                                            and I guess I need to set the rights for the file to a specific value...
