"Out of Range" Issue on JetRacer pro IA Kit for Road Following

[Eliott-0]

Hello everyone !

I am curently stuck by a simple error when I try to run the road following notebook on my JetRacer.
I created my dataset and trained my road following model. Then, I optimized the model and got my "road_following_model_trt.pth" file.

I first faced an I2C issue, because the program was on default and used 0x60 bus. But when i checked, I saw that my motors were on 0x40 and 0x42.
So i tried like this :
car = NvidiaRacecar(i2c_address1=0x42, i2c_address2=0x40)
but I got an I/O error on 0x42 address, so i used only the 0x40 like this :
car = NvidiaRacecar(i2c_address1=0x40, i2c_address2=0x40)

It solved temporally my problem, but now i'm stuck with and "Out of range" issue on my car.steering.
I tried to Clamp my value between [-1;1] but it doesnt worked.
Then, I tried to modify directly the library by modifying "adafruit_pca9685.py" file.
I changed this :
def duty_cycle(self, value):
if not 0 <= value <= 0xFFFF:
raise ValueError("Out of range")

    if value == 0xFFFF:
        self._pca.pwm_regs[self._index] = (0x1000, 0)
    else:
        # Shift our value by four because the PCA9685 is only 12 bits but our value is 16
        value = (value + 1) >> 4
        self._pca.pwm_regs[self._index] = (0, value)

for this :
def duty_cycle(self, value):
if not 0 <= value <= 0xFFFF:
print(f"DEBUG: duty_cycle value out of range: {value}, clamping")
value = max(0, min(value, 0xFFFF))

if value == 0xFFFF:
    self._pca.pwm_regs[self._index] = (0x1000, 0)
else:
    # Shift our value by four because the PCA9685 is only 12 bits but our value is 16
    value = (value + 1) >> 4
    self._pca.pwm_regs[self._index] = (0, value)

(chat gpt advice)
That didn't solved my problem either...

That's why I am asking you if someone is willing to help me ?
Maybe it happens because i used same I2C address for both of my servo and motor, but I couldn't find any other solutions.

Thant you very much for your help and for your time !
Have a nice day !
Eliott.
