Hi All ~ I've been following various sites/forums/guides and adding my own input to make my Logitech G29 Shifter display it's gear on a home built 7-segment display. Tested and confirmed the LED segments work on their own. I put the code I made into an Arduino Leonardo and I got it all to work EXCEPT that I can't get gears 1, 3, and 5 to light up their corresponding parts of the 7-segment display. The 2, 4, 6, and Reverse all light up their parts on the 7-segment display. I'm using Windows 11 Home on an Acer laptop so I opened the game controller section of Windows and confirmed that the computer is reading all of the gears (1 to 6 and reverse) so I know it's not an issue with the actual Logitech G29 Shifter. I'm BRAND new to Arduino and I'm trying to teach myself but this is going to be a gift for my son's birthday next week and I'm just stuck. Can ya'll take a look at the code and let me know. Thank you in advance! Best, Alan, RN
