I am learning how to build a basic robot using a raspberry pi and an L298N h-bridge.
I have followed this tutorial successfully i:e the single DC motor I have connected does work in response to the code. My problem is when I use the code, below, the motor does not work:
import sys import time import RPi.GPIO as GPIO GPIO.setwarnings(False) Forward = 23 Backward = 24 Enable = 25 GPIO.setmode(GPIO.BCM) GPIO.setup(Forward, GPIO.OUT) GPIO.setup(Backward, GPIO.OUT) GPIO.setup(Enable, GPIO.OUT) p=GPIO.PWM(Enable, 1000) p.start(25) def forward(t): GPIO.output(Forward, GPIO.HIGH) GPIO.output(Backward, GPIO.LOW) print("Moving Forward") def reverse(t): GPIO.output(Forward, GPIO.LOW) GPIO.output(Backward, GPIO.HIGH) print("Moving Backward") while(1): forward(3) # reverse(3) GPIO.cleanup()
When I run the script, I get the following error:
Traceback (most recent call last): File "move2.py", line 43, in forward(3) File "move2.py", line 27, in forward GPIO.output(Forward, GPIO.HIGH)
RuntimeError: Please set pin numbering mode using GPIO.setmode(GPIO.BOARD) or GPIO.setmode(GPIO.BCM)
I had set the pin mode to BCM earlier in the code so I'm not sure why the error is occurring.
I'm not sure what I'm doing wrong.
A little help, please?
