hi ppl

im trying to set up a game controller from my old logitech controller. I want to use the pedals as they are ok and transform the brake padel with a load cell.
so i hooked everything up and copy and pasted some code from everywhere i could get it.

so this is my code

// How many samples to take at initialization of the library to zero
// out the offset of the load cell.
#define BRAKE_PEDAL_LOAD_BEAM_CELL_TARE_REPS  10

// Sanity check for the load cell readings. This will typically be to
// prevent from loading negative values if/when the load cell is pulled
// in the wrong direction
#define BRAKE_PEDAL_LOAD_BEAM_CELL_MAX_VAL  2000000

// This setting links the maximum effort applied to the pedal to the
// maximum value sent to the joystick interface.
// The joystick interface expects a value ranging from 0 t0 1023. Adjust
// this number to your liking, so the joystick will read 1023 at the maximum
// force you feel comfortable applying to the brake pedal (without braking it).
// The hardware I am using is 3D printed and I do not recommend this value
// Be set any lower than 1100. Any lower value will require more force to
// be applied to the pedal, and may damage the 3D printed parts.
#define BRAKE_PEDAL_LOAD_BEAM_CELL_SCALING  1100

  // While this is happening
  brake_pedal.begin(1 /* DAT */, 0 /* CLK */, 128 /* GAIN */); 
  brake_pedal.tare(BRAKE_PEDAL_LOAD_BEAM_CELL_TARE_REPS);
  
 // Joystick.useManualSend(true);
} // setup

{
  int32_t brake_value ;
  
  brake_value = brake_pedal.get_value(1);

  if((brake_value > BRAKE_PEDAL_LOAD_BEAM_CELL_MAX_VAL) || 
     (brake_value < 0))
  {
    brake_value = 0;
  }
  
  brake_value /= BRAKE_PEDAL_LOAD_BEAM_CELL_SCALING;
  
  Joystick.X(brake_value);
  Joystick.Y(analogRead(2));
  Joystick.Z(analogRead(3));
  
  Joystick.send_now();
} // loop

so i got the loadcell to work and i thought adding the other 2 pedals shouldnt be that big a deal. but i was wrong, i cant get it to work after reading and wathcing lots of tutorials. what i see is the brakepedal moving but the z is doing some random thing and the y isnt doing anything

i must have done something wrong here. could you guys help me in the right direction?

How are pedal electronics wired to pins 2 and 3?
