我做了一个项目,我需要移动两台电机,它们有不同的动作。有代码:
import RPi.GPIO as GPIO ## Import GPIO library
import time ## Import 'time' library. Allows us to use 'sleep'
import sys
GPIO.setmode(GPIO.BOARD) ## Use board pin numbering
GPIO.setup(19, GPIO.OUT) ## Setup GPIO Pin 11(motor b enable) to OUT
GPIO.setup(16, GPIO.OUT) ## Setup GPIO Pin 11(motor a enable) to OUT
GPIO.setup(22, GPIO.OUT) ## Setup GPIO Pin 11(motor a control) to OUT
GPIO.setup(18, GPIO.OUT) ## Setup GPIO Pin 11(motor a control) to OUT
GPIO.setup(23, GPIO.OUT) ## Setup GPIO Pin 11(motor b control) to OUT
GPIO.setup(21, GPIO.OUT) ## Setup GPIO Pin 11(motor b control) to OUT
GPIO.output(16, False) ## disable motor a
GPIO.output(19, True) ## enable motor b
p=GPIO.PWM(19,50) ## frequency 50
p.start(1)
try:
while True:
GPIO.output(22, False) ## dont run motor a
GPIO.output(18, False) ## dont run motor a
GPIO.output(23, True) ## run motor b
GPIO.output(21, False) ## run motor b
p.ChangeDutyCycle(35) ## duty cycle 10%
except KeyboardInterrupt:
pass
p.stop()
GPIO.cleanup()
sys.exit()
代码#2
import RPi.GPIO as GPIO
from time import sleep
import sys
GPIO.setmode(GPIO.BOARD)
Motor1A = 22
Motor1B = 18
Motor1E = 16
Motor2A = 23
Motor2B = 21
Motor2E = 19
GPIO.setup(Motor1A,GPIO.OUT)
GPIO.setup(Motor1B,GPIO.OUT)
GPIO.setup(Motor1E,GPIO.OUT)
GPIO.setup(Motor2A,GPIO.OUT)
GPIO.setup(Motor2B,GPIO.OUT)
GPIO.setup(Motor2E,GPIO.OUT)
print "Going forwards"
GPIO.output(Motor1A,GPIO.HIGH)
GPIO.output(Motor1B,GPIO.LOW)
GPIO.output(Motor1E,GPIO.HIGH)
GPIO.output(Motor2A,GPIO.HIGH)
GPIO.output(Motor2B,GPIO.LOW)
GPIO.output(Motor2E,GPIO.HIGH)
sleep(2)
print "Now stop"
GPIO.output(Motor1E,GPIO.LOW)
GPIO.output(Motor2E,GPIO.LOW)
GPIO.cleanup()
sys.exit()
我想将两个代码混合在一起。我的意思是,将这两个代码转换为具有两个不同速度的代码。
或者如果有人知道另一个代码,我会非常感激
我该怎么做?
答案 0 :(得分:1)
说真的,使用gpiozero,它会更有趣并将您的代码转换为:
from gpiozero import Motor
from time import sleep
motorA = Motor(22, 18) # your gpio pins go here
motorB = Motor(23, 21)
motorA.forward(0.5) # half speed
motorB.forward(0.5)
sleep(2) # wait 2 seconds before stopping the motors
motorA.stop()
motorB.stop()
然后,您可以更进一步,使用Robot
课程(文档here),让一切变得更加轻松:
from gpiozero import Robot
from time import sleep
robot = Robot(left=(22, 18), right=(23, 21))
robot.forward(1) # full speed
sleep(2)
robot.stop()
机器人类还有一些功能,例如:
robot.left()
robot.right()
最有可能的是,如果您尚未使用该库,则必须先安装该库。在终端上键入以下内容以进行此操作。
pip install gpiozero
