Using Leonardo for Logitech G27 standalone shifter

Projects Programming
1

EDIT: Forget method 2. Focusing on method 1. Replied with full sketch below.

Gonna try to keep it brief.

It went from bad to worse. I tried two different tutorials to get this build to work.

The first method only recognized gears 1 through 6 but not 7. Gear 7 is used as reverse gear. Gear 7 is actually only recognized for 1 to 2 minutes while it's searching for gears 5 and 6. Once gears 5 and 6 are eventually discovered, gear 7 can never be used again. This happened twice.

The second method didn't recognize any input from my shifter and then I ended up with this after retrying multiple times:

C:\Users\Name\AppData\Local\Temp\ccX6YReG.ltrans0.ltrans.o: In function main': C:\Users\Name\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.6\cores\arduino/main.cpp:43: undefined reference to setup'
C:\Users\Name\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.6\cores\arduino/main.cpp:46: undefined reference to `loop'
collect2.exe: error: ld returned 1 exit status

exit status 1

Compilation error: exit status 1

The second method (when compiling still worked) gave me this: "Error: 13 INTERNAL: Library install failed: library not valid" no matter how many times I try.

    This will copy the selected text to the clipboard.
  5. In a forum reply here, click on the reply field.
  6. Click the </> icon on the post composer toolbar.
    This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
    Code block
  7. Press Ctrl+V.
    This will paste the compilation output into the code block.
  8. Move the cursor outside of the code block markup before you add any additional text to your reply.
  9. Repeat the above process if your sketch has multiple tabs.
  10. Click the Reply button to post the output.

Please post a link to where you downloaded the library file you are attempting to install.

If you are following some tutorial, please post a link to it.

Joystick library master zip that I used because the one linked in YouTube video doesn't work:

Here's the tutorial I'm following for this build:

6

Since it doesn't include the error messages you shared in your previous post, I'll assume you already solved that problem:

I'll provide instructions you can follow to install it:

  1. Click the following link to open the library's GitHub repository:
    GitHub - MHeironimus/ArduinoJoystickLibrary: An Arduino library that adds one or more joysticks to the list of HID devices an Arduino Leonardo or Arduino Micro can support.
  2. Click the "<> Code ▾" button.
  3. Select Download ZIP from the menu.
  4. Wait for the download to finish.
  5. Select Sketch > Include library > Add .ZIP Library from the Arduino IDE menus.
  6. Select the downloaded file.
  7. Click the Open button.
  8. Wait for Arduino IDE to show a "Successfully installed library ... notification.

If you follow those instructions, you should not get the error you reported previously:

7

Yea I'm not having trouble with the original error message anymore.

Build Method #1:
The "library not valid" error was actually for another zip, the one from my second method. I don't want to use the second method if I don't have to. The first method is good but I just need to figure out why it's not recognizing button 7.

Build Method #2:
The one that gave me the "library not valid" is this one: SHIFTERS – AMSTUDIO
Scroll all the way down to the " DIY LOGITECH USB SHIFTER ADAPTER" section. The one I downloaded from there is giving me the "library not valid" error message.
I managed to find their sketch on github: LOGITECH_USB_ADAPTER/Logitech_Shifter_USB.ino at master · AM-STUDIO/LOGITECH_USB_ADAPTER · GitHub
How can I load that sketch along with the ArduinoJoystickLibrary together into my Leonardo?

8

Judging by the error messages, the library you chose is not compatible with the code.
Use the one that came with the video

9

Just removed the library that gave me the error message and used the library that came with the video. Got a new error message:

Could you please show the file Joystick.h ?

11

Having trouble locating the sketch to copy and paste here. It's this one: Release Version 1.1.3 · dmadison/Sim-Racing-Arduino · GitHub

12

Sorry, gave the wrong link in previous post. Refresh please.

13

No, wait. You asked for the joystick.h. It's this one: GitHub - MHeironimus/ArduinoJoystickLibrary: An Arduino library that adds one or more joysticks to the list of HID devices an Arduino Leonardo or Arduino Micro can support.

14

Are you installed exact this Joystick library?
The library from the link has type Joystick_, so you hardly faced with errors that you showed above.

You need to install correct library.

15

Yes, installed this exact one. Downloaded it a few times now. I download the zip file. In Aruduino IDE, I went to Sketch>Include Library>Add .ZIP Library and added this specific library. I've removed and added and deleted and downloaded multiple times to make sure. Still getting the same error message.

16

Your code compiled fine for me. I installed Sim-Racing and ArduinoJoystick libraries from your links and all compiled without errors.

So you should check your installation.
I use Arduino IDE v1.8.19 on Fedora Linux

17

I just uninstalled everything and installed it again. I'm back to square one again using method 1. My shifter is partially working. It recognizes gears 1 through 4 and 7 temporarily as it searches for gears 5 and 6. Once it recognizes gears 5 and 6, gear 7 can never be activated again. Is there something in the sketch I'm missing?

18

I don't see gear 7 in your code, it includes gears from 1 to 6 only:

19

I guess I should've said button 7. It's the reverse gear. It requires the shifter to be pushed down before shifting into 6th gear to activate the reverse gear. When the shifter is plugged into the steering wheel it came with, it shows up as Button 7.

Plugging the shifter back into the original steering wheel, all the buttons and gears still work normally. Once I use it as a standalone unit using the Leonardo, button 7/reverse gear doesn't work.

Is there something I can add to the sketch for it to recognize the down press on the shifter before moving into 6th gear for it to recognize as button 7? I have no knowledge of coding but I can copy and paste lines of code.

I've ran out of replies here as a new user and will need to wait 21 hours before I can submit another reply. Here's a video of Button 7/Reverse Gear. Hope you see this. How To Shift Into Reverse (Button 15) On Logitech G27 - YouTube

20

I don't understand what you mean as Button 7, I don't see anything similar in your code. Please point me a line, where this button defined or where it used.
