Python code for Raspberry Pi to generate square wave at 20% duty cycle at GPIO7 pin 26 of P1 with 1kHz frequency

sqr_1ch_1k_20p.py

#!/usr/bin/python
#####
# This program would generate PWM on GPIO7 Pin 26 of P1
# with 20% Duty Cycle at 1kHz
######
import RPi.GPIO as GPIO
from time import sleep

GPIO.setmode(GPIO.BCM)
GPIO.setup(7,GPIO.OUT)
p=GPIO.PWM(7,1190)
p.start(13.8)
raw_input("Press Enter key to Stop 1kHz PWM @ 20% duty cycle")
GPIO.cleanup()

Hey, just wanted to thank you for providing this program. I wasn't sure how to generate square waves, but between this and the docs it all makes sense now.

regards,
