Cannot put all GPIO pins to high 4 channel motor controller
0
I'm trying to run 4 motors with my raspberry pi using a cytron 4 channel motor driver.
My code works for reverse and for left/right turns but I cannot put all GPIO pins to high at the same time.
parts of the code:
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BOARD)
MOTOR1Direction = 11
MOTOR1Enable = 13
etc for other 3 motors
GPIO.setup(MOTOR1Direction,GPIO.OUT)
GPIO.setup(MOTOR1Enable,GPIO.OUT)
etc for the other 3 motors
p1 = GPIO.PWM(MOTOR1Enable, 100)
etc for the other 3 motors
def forward(pwmVal):
GPIO.output(MOTOR1Direction, GPIO.HIGH)
GPIO.output(MOTOR2Direction, GPIO.HIGH)
GPIO.output(MOTOR3Direction, GPIO.HIGH)
GPIO.output(MOTOR4Direction, GPIO.HIGH)
p1.start(pwmVal)
p2.start(pwmVal)
p3.start(pwmVal)
p4.start(pwmVal)
def reverse(pwmVal):
GPIO.output(MOTOR1Direction, GPIO.LOW)
GPIO.output(MOTOR2Direction, GPIO.LOW)
GPIO.output(MOTOR3Direction, GPIO.LOW)
GPIO.output(MOTOR4Direction, GPIO.LOW)
p1.start(pwmVal)
p2.start(pwmVal)
p3.start(pwmVal)
p4.start(pwmVal)
def left(pwmVal):
GPIO.output(MOTOR1Direction, GPIO.HIGH)
GPIO.output(MOTOR2Direction, GPIO.HIGH)
GPIO.output(MOTOR3Direction, GPIO.LOW)
GPIO.output(MOTOR4Direction, GPIO.LOW)
p1.start(pwmVal)
p2.start(pwmVal)
p3.start(pwmVal)
p4.start(pwmVal)
So when I run reverse(100) it works, same for left/right, but when I run forward(100) nothing happens. If I change any one of the HIGH's in the forward code to LOW it works?

Which pins did you use for the motors?
– FMarazzi
Nov 20 '18 at 17:36
the Pi's GPIO pins for all of them, like 11 & 13 for motor 1

Not a duplicate? Very different problem as I do have connection but only have issues when ALL 4 pins are high
– Christel

I mean which pins specifically. Maybe the problem might be related to the specific pins you used, or it's a power issue. It was just to have all the information.
