WiringPi: An implementation of most of the Arduino Wiring
|
|
functions for the Raspberry Pi
|
|
|
|
WiringPi2: WiringPi version 2 implements new functions for managing IO expanders.
|
|
|
|
Prerequisites:
|
|
You must have python-dev and python-setuptools installed
|
|
If you manually rebuild the bindings with swig -python wiringpi.i
|
|
then cat wiringpi_class.py >> wiringpi.py to get the class-based wrapper
|
|
|
|
Get/setup repo:
|
|
git clone https://github.com/Gadgetoid/WiringPi2-Python.git
|
|
cd WiringPi2-Python
|
|
|
|
Build & install with:
|
|
sudo python setup.py install
|
|
|
|
Or Python 3
|
|
sudo python3 setup.py install
|
|
|
|
Class-based Usage:
|
|
No classes have been created for this version yet.
|
|
|
|
Usage:
|
|
import wiringpi
|
|
wiringpi.wiringPiSetup // For sequential pin numbering, one of these MUST be called before using IO functions
|
|
OR
|
|
wiringpi.wiringPiSetupSys // For /sys/class/gpio with GPIO pin numbering
|
|
OR
|
|
wiringpi.wiringPiSetupGpio // For GPIO pin numbering
|
|
|
|
Setting up IO expanders (This example was tested on a quick2wire board with one digital IO expansion board connected via I2C):
|
|
wiringpi.mcp23017Setup(65,0x20)
|
|
wiringpi.pinMode(65,1)
|
|
wiringpi.digitalWrite(65,1)
|
|
|
|
General IO:
|
|
wiringpi.pinMode(1,1) // Set pin 1 to output
|
|
wiringpi.digitalWrite(1,1) // Write 1 HIGH to pin 1
|
|
wiringpi.digitalRead(1) // Read pin 1
|
|
|
|
Bit shifting:
|
|
wiringpi.shiftOut(1,2,0,123) // Shift out 123 (b1110110, byte 0-255) to data pin 1, clock pin 2
|
|
|
|
Serial:
|
|
serial = wiringpi.serialOpen('/dev/ttyAMA0',9600) // Requires device/baud and returns an ID
|
|
wiringpi.serialPuts(serial,"hello")
|
|
wiringpi.serialClose(serial) // Pass in ID
|
|
