This example is supposed to control micro servo motor.
If you want make it work with your ESC + Motor pairs, you should change the code as following:
import sys
import time
import navio.pwm
import navio.util
navio.util.check_apm()
PWM_OUTPUT = 0
SERVO_MIN = 1.250 #ms
ESC_INIT = 1.100 #ms
with navio.pwm.PWM(PWM_OUTPUT) as pwm:
pwm.set_period(50)
pwm.enable()
# initialize ESC: set initial duty_cicle for 3 sec
for i in range(30):
pwm.set_duty_cycle(ESC_INIT)
time.sleep(0.1)
while (True):
pwm.set_duty_cycle(SERVO_MIN)
time.sleep(0.1)
