hola chicos, tengo un codigo que copie de internet, cuando yo le digo que me de un paso el motor me da un paso y medio como hago, no se si el codigo esta mal, o asi no se programa......
nota: apenas estoy comenzando en este mundo y no se muy bn de la programacion.. aqui les dejo el codigo
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
enable_pin = 18
coil_A_1_pin = 4
coil_A_2_pin = 17
coil_B_1_pin = 23
coil_B_2_pin = 24
GPIO.setup(enable_pin, GPIO.OUT)
GPIO.setup(coil_A_1_pin, GPIO.OUT)
GPIO.setup(coil_A_2_pin, GPIO.OUT)
GPIO.setup(coil_B_1_pin, GPIO.OUT)
GPIO.setup(coil_B_2_pin, GPIO.OUT)
GPIO.output(enable_pin, 1)
def forward(delay, steps):
for i in range(0, steps):
setStep(1, 0, 1, 0)
time.sleep(delay)
setStep(0, 1, 1, 0)
time.sleep(delay)
setStep(0, 1, 0, 1)
time.sleep(delay)
setStep(1, 0, 0, 1)
time.sleep(delay)
def backwards(delay, steps):
for i in range(0, steps):
setStep(1, 0, 0, 1)
time.sleep(delay)
setStep(0, 1, 0, 1)
time.sleep(delay)
setStep(0, 1, 1, 0)
time.sleep(delay)
setStep(1, 0, 1, 0)
time.sleep(delay)
def setStep(w1, w2, w3, w4):
GPIO.output(coil_A_1_pin, w1)
GPIO.output(coil_A_2_pin, w2)
GPIO.output(coil_B_1_pin, w3)
GPIO.output(coil_B_2_pin, w4)
while True:
delay = raw_input("Delay between steps (milliseconds)?")
steps = raw_input("How many steps forward? ")
forward(int(delay) / 1000.0, int(steps))
steps = raw_input("How many steps backwards? ")
backwards(int(delay) / 1000.0, int(steps))
