RPi.GPIO-OdroidC1

This is a RPi.GPIO module for Odroid C1 board.

• GPIO input and output
• GPIO interrupts (callbacks when events occur on input gpios)
• Hardware/Software PWM
• Hardware ADC

Install this package by executing:

sudo python setup.py install

Examples

Hardware PWM

Odroid-C1 board has two PWM pins, #33 and #19.
To use hardware PWM, you have to load kernel PWM module.

sudo modprobe pwm-meson npwm=1 # or npwm=2
sudo modprobe pwm-ctrl

RPi.GPIO.HWPWM provides hardware PWM for Odroid-C1.
Example of using hardware PWM is as follows:

import RPi.GPIO as GPIO
import time

pwm_pin = 33
GPIO.setmode(GPIO.BOARD)
GPIO.setup(pwm_pin, GPIO.OUT)
GPIO.output(pwm_pin, False)
pwm = GPIO.HWPWM(pwm_pin, 100)
pwm.start(0)
time.sleep(1)
pwm.ChangeDutyCycle(50)
time.sleep(1)
pwm.ChangeDutyCycle(100)

ADC

Odroid-C1 board has two ADC pins, 0(#40) and 1(#39).
RPi.GPIO.ADC provides ADC function for Odroid-C1.
Example of using ADC is as follows:

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BOARD)
adc = GPIO.ADC(0)
while True:
    reading = adc.read()
    voltage = reading * 1.8 / 1024
    print "value=%d,\t %f V" % (reading, voltage)
    time.sleep(1)
