# CHIP_IO
|
|
A CHIP GPIO library
|
|
|
|
Manual::
|
|
|
|
sudo ntpdate pool.ntp.org
|
|
sudo apt-get update
|
|
sudo apt-get install build-essential python-dev python-pip -y
|
|
git clone git://github.com/xtacocorex/CHIP_IO.git
|
|
cd CHIP_IO
|
|
sudo python setup.py install
|
|
cd ..
|
|
sudo rm -rf CHIP_IO
|
|
|
|
**Usage**
|
|
|
|
Using the library is very similar to the excellent RPi.GPIO library used on the Raspberry Pi. Below are some examples.
|
|
|
|
**GPIO Setup**
|
|
|
|
Import the library, and setup as GPIO.OUT or GPIO.IN::
|
|
|
|
import CHIP_IO.GPIO as GPIO
|
|
GPIO.setup("CSID0", GPIO.OUT)
|
|
|
|
You can also refer to the pin number::
|
|
|
|
GPIO.setup("U14_31", GPIO.OUT)
|
|
|
|
**GPIO Output**
|
|
|
|
Setup the pin for output, and write GPIO.HIGH or GPIO.LOW. Or you can use 1 or 0.::
|
|
|
|
import CHIP_IO.GPIO as GPIO
|
|
GPIO.setup("CSID0", GPIO.OUT)
|
|
GPIO.output("CSID0", GPIO.HIGH)
|
|
|
|
**GPIO Input**
|
|
|
|
Inputs work similarly to outputs.::
|
|
|
|
import CHIP_IO.GPIO as GPIO
|
|
GPIO.setup("CSID0", GPIO.IN)
|
|
|
|
Polling inputs::
|
|
|
|
if GPIO.input("CSID0"):
|
|
print("HIGH")
|
|
else:
|
|
print("LOW")
|
|
|
|
Waiting for an edge (GPIO.RISING, GPIO.FALLING, or GPIO.BOTH::
|
|
|
|
GPIO.wait_for_edge(channel, GPIO.RISING)
|
|
|
|
Detecting events::
|
|
|
|
GPIO.add_event_detect("CSID0", GPIO.FALLING)
|
|
#your amazing code here
|
|
#detect wherever:
|
|
if GPIO.event_detected("CSID0"):
|
|
print "event detected!"

**ADC**::

|
|
|
|
**Running tests**
|
|
|
|
Install py.test to run the tests. You'll also need the python compiler package for py.test.::
|
|
|
|
opkg update && opkg install python-compiler
|
|
#Either pip or easy_install
|
|
pip install -U pytest
|
|
easy_install -U pytest
|
|
|
|
Execute the following in the root of the project::
|
|
|
|
py.test
|
