GPIO Pins Library Issue

Autonomous Machines Jetson & Embedded Systems Jetson Nano

Hi,

I am trying to use the GPIO pins on Jetson Nano 2GB for this applications;

  • Switching ON and OFF devices. Such as, LED and Buzzer.
  • Controlling a servo motor with a servo motor driver module (PCA9685) connected to the SDA and SCL pins (i2c) on Jetson Nano.

However, before I compiled both of the program it works fine individually. Once I compiled both of it, there is an error as shown below.

This are the codes of the program,

import RPi.GPIO as GPIO 
import time
from adafruit_servokit import ServoKit
kit=ServoKit(channels=16)

led1=7
led2=11
led3=13
buzz=15
sleepTime=1

GPIO.setmode(GPIO.BOARD) 

GPIO.setup(led1,GPIO.OUT) 
GPIO.setup(led2,GPIO.OUT) 
GPIO.setup(led3,GPIO.OUT) 
GPIO.setup(buzz,GPIO.OUT) 

while (True):

GPIO.output(led1,True) 
time.sleep(sleepTime) 
GPIO.output(led1,False) 
time.sleep(sleepTime)

GPIO.output(led2,True)
time.sleep(sleepTime)
GPIO.output(led2,False)
time.sleep(sleepTime)

GPIO.output(led3,True)
time.sleep(sleepTime)
GPIO.output(led3,False)
time.sleep(sleepTime)

GPIO.output(buzz,True)
time.sleep(sleepTime)
GPIO.output(buzz,False)
time.sleep(sleepTime)

for i in range(0,180,2):
    kit.servo[0].angle=i
    time.sleep(.01) #lower = Faster
for i in range(180,0,-2):
    kit.servo[0].angle=i
    time.sleep(.01)


 GPIO.cleanup(led1) 
 GPIO.cleanup(led2) 
 GPIO.cleanup(led3) 
 GPIO.cleanup(led3)

Thank you.

hello faiz26,

here’s Jetson-IO tool to simplify the configuration of the I/Os exposed by the 40‑pin expansion header. please refer to developer guide, Configuring the 40-Pin Expansion Header.
thanks
