I was looking at the program UnoJoy for it as it seems it will communicate and show up on Windows as a Joystick but I don't know how to configure it with the sketches. It can be done but it is a pain ... Get a teensy Share this post Link to post Share on other sites

Is there a tutorial? Anyways, I'm looking to get a Teensy in a week, (Gotta love birthdays), but if I don't get one, it'd be nice to have something to fall back to.

Anyways, I'm looking to get a Teensy in a week, (Gotta love birthdays), but if I don't get one, it'd be nice to have something to fall back to. I've done it with UnoJoy. But as soon as you flash UnoJoy you can't debug nor upload a sketch anymore: you have to go through the whole sequence for the slightest change: flash the normal firmware, upload your sketch, flash UnoJoy, check if it works without being able to debug, start over again ... It is a real pain: I switched to Teensy after few hours. Edited June 22, 2016 by pascalh Share this post Link to post Share on other sites

On a side note, have you ever modded a MOMO wheel so that it could go 900 degrees? It doesn't have to be a MOMO, I just want to know how to make stops for it. I'm thinking some sort of screw hooked up to a gear or something. Share this post Link to post Share on other sites

If the pinout is not published yet, the only way is to reverse engineer it: Disassemble the shifter Find to which IC pin each connector pin is connected using an ohmmeter Download the IC datasheet (most likely a shift register) and determine which connector pin is connected to data, clock and analog inputs Find GND and +5V pins Change or write the code accordingly This is how I did for the G25 shifter Edited July 17, 2016 by pascalh 1 Mistawes reacted to this Share this post Link to post Share on other sites

If somebody could test this, it would not only save some time, --it would save me from trying to figure out how to find the IC Datasheet for the Shifter .-- (I realize now that IC means integrated circuit and it'd be easier to find the data sheet once I get the Driving Force Shifter and open it so I could find a model number or something *facepalm*) Edited June 23, 2016 by Stealthblackbird A realization Share this post Link to post Share on other sites

For instance if +5V on one side is connected to an output on the other side, the output will most likely be burned. Share this post Link to post Share on other sites

They do say that the G27 shifter is compatible with the G920/G290 wheel so the Logitech G Driving Force shifter may possibly be the same pinout. I've realized that if I open up the Logitech G Driving Force Shifter it would void my warranty...and I want to replace it if it breaks under warranty so, I would really like it if somebody else could test this for me. My shifter has arrived and so has my teensy so I have all the stuff I need (don't you love birthdays?). PS: sorry for the late reply, been busy with vacation and other things.

Leo Bodnar is advertising their interface to be compatible with G25, G27 and G29 shifters (http://www.leobodnar.com/shop/index.php?main_page=product_info&products_id=188) So they could be pin to pin compatible. At least they can't be incompatible (inverted power lines etc...) Edited July 15, 2016 by pascalh Share this post Link to post Share on other sites

Stealthblackbird 1 Report post Posted July 16, 2016 (edited) Woah I just had a great idea! To find +5V and ground I could just take my multimeter, switch it to the mode where it beeps when there is a closed circuit or there is a connection between two pins and voila! I would find the +5V and Ground. Edited July 16, 2016 by Stealthblackbird Words Share this post Link to post Share on other sites

If you do that on power lines you could burn something. Use voltmeter mode set on 5V DC. 1 Stealthblackbird reacted to this Share this post Link to post Share on other sites

Stealthblackbird 1 Report post Posted July 16, 2016 I know this is the third post in a row by me but this is kind of important. I just noticed this label on my Shifter that states the rating is 3.3V. I've included a picture of it as an attachment. If I'm thinking right, if I put +5V into this thing, it will fry it. What do I do? Share this post Link to post Share on other sites
