OPi.GPIO error

yusufSAİTc

i am using a orange pi 3 lts and i want to use my gpio pins and i do a nano ledBlink.py and then i do small program useing the OPi.GPİO library and i write a program that just turns HIGH AND LOW 4 time but i keep geting this error it i been trying to fix this error for over a 4 months but i can fix it i would be very happy if one help me and know there is PYa20 library i can also use but i realy want to use OPi.GPIO  
import OPi.GPIO as GPIO here is the ledBlink program import time                                                                                                                GPIO.setmode(GPIO.BOARD)LED_PIN = 7GPIO.setwarnings(False)GPIO.setup(LED_PIN, GPIO.OUT)try:    while True:        GPIO.output(LED_PIN, GPIO.TRUE)        time.sleep(1)        GPIO.output(LED_PIN, GPIO.FALSE)        time.sleep(1)except KeyboardInterrupt:                                                                                                         GPIO.cleanup()

I am a newer on Orange Pi 5 and do not own an Orange Pi 3.
Please reference to: https://github.com/orangepi-xunlong/wiringOP
But code in above web page dose not support Orange Pi 5 at this moment.
Therefor, I modified your code as below and have no test.
Hope these information can help you.


import OPi.GPIO as GPIO  # here is the led Blink program
import time

GPIO.setboard(GPIO.OPi3)
GPIO.setmode(GPIO.BOARD)
LED_PIN = 7
#GPIO.setwarnings(False)

GPIO.setup(LED_PIN, GPIO.OUT)
try:
    while True:
        GPIO.output(LED_PIN, 1)
        time.sleep(1)
        GPIO.output(LED_PIN, 0)
        time.sleep(1)
        
except KeyboardInterrupt:
    GPIO.output(LED_PIN, 0)
    GPIO.cleanup()

An intriguing discussion may be worth comment. I do think that you should write regarding this topic, may possibly not often be a taboo subject but usually people are there are not enough to dicuss on such topics. To a higher. Cheers        bokep indonesia

How can i extend the range of a Wireless N router? I have an Xtreme N handheld router (Dlink). I have to extend the reach in the wireless signal. I know how to do it for the G signal. I want to know how to do the idea for an N sign. Is it possible make use of regular N routers as repeaters. If so, how to configure them. Thanks for that information.        789bet

Eh oui et aussi pas vraiment. Certes en effet on détermine de nouvelles sources qui se référent les memes significations. Non étant donné que il n’est pas suffisant de répéter ce que tout le monde est en mesure de voir chez certains sites tiers puis le traduire tant simplement?        hb88
