Invalid Channels

[kaloomte]

Hi, sorry for if i miss something.
This is my code for taking input from GPIO 10.

import Jetson.GPIO as GPIO 

class CheckGPIO():

    def __init__(self): 
        GPIO.setmode(GPIO.BOARD) 
        GPIO.setwarnings(False) 
        self.CONVEYOR_BACKWARD_PIN = 10 
        GPIO.setup(self.CONVEYOR_BACKWARD_PIN, GPIO.IN) 

    def _check_conveyor(self): 
        if GPIO.input(self.CONVEYOR_BACKWARD_PIN): 
            print("LOW") 
        else: 
            print("HIGH") 

checkclass = CheckGPIO() 
checkclass._check_conveyor()

But i got an error. Here is error log;

Traceback (most recent call last):

    check = CheckGPIO()

We dont support PIN 10. You can read this phthon file to see what pins are supported. https://github.com/NVIDIA/jetson-gpio/blob/master/lib/python/Jetson/GPIO/gpio_pin_data.py

It should be in the column where the list is “7,11,12,13,…”
