Hello,
I'm looking for some help as I can't resolve two issues with my Teensy LC card running Retropie and Raspberry PI 3A +. From time to time I make handheld consoles and bartop for fun (https://www.elektronicaone.fr/) to take on new relevant challenges, but here I am blocking .
Problem nĀ° 1: The analog joystick:
I am unable to center or calibrate my analog joystick. When I let the joystick in the home position (without touching it), it always positions itself to the right, visible in the Windows utility joy.cpl. I tried all the codes I found on the Internet and in the examples (Sketches) from the Arduino IDE, i modified the X & Y position values of the joystick in the code, I replaced the joystick, the Teensy LC card but no change.
Result: In Retropie, in the Emulationstation menu, no problem. But when I enter in a game and to the Retroarch menu, the right direction is automatically maintained as if I were moving the joystick to the right. I also changed the UDEV driver to SLD2, reinstall Retropie, launched Retropie update, Raspberry pi firmware and still no resolution
Problem nĀ°2: Teensy LC controller does not work in Retropie 4.7.1 games
My Teensy LC Joystick and Buttons work fine in Emulationstation but not in games.
it works a few rare times (which allowed me to see that the joystick went to automatically go to the right.)
What I did to try to fix this but still issue.
-force the Teensy lc controller in Player 1 in Retroarch
-Reset the controller in Emulationstation to remove all controllers and remap the keys.
-Change the Gamepad drivers in Retroarch: UDEV, SDL2 ...
-Install the Raspbian OS then Retropie
In reading my topic , I realize that the problem may be definitely between the computer screen and the keyboard (this is a French expression )
Thank you in advance for your help.
Here is one of the Teensly Gamepad code used
