| WiringPi 2 for Python |
| ====== |
| |
| 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. |
| |
| Testing: |
| ======== |
| Build with gcc version 4.6.3 (Debian 4.6.3-14+rpi1) |
| Built against Python 2.7.2, Python 3.2.3 |
| |
| Prerequisites: |
| ============== |
| You must have python-dev and python-setuptools installed |
| If you manually rebuild the bindings with swig -python wiringpi.i |
| |
| 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: |
| ================== |
| Description incoming! |
| |
| Usage: |
| ====== |
| import wiringpi2 |
| wiringpi2.wiringPiSetup // For sequential pin numbering, one of these MUST be called before using IO functions |
| OR |
| wiringpi2.wiringPiSetupSys // For /sys/class/gpio with GPIO pin numbering |
| OR |
| wiringpi2.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): |
| wiringpi2.mcp23017Setup(65,0x20) |
| wiringpi2.pinMode(65,1) |
| wiringpi2.digitalWrite(65,1) |
| |
| General IO: |
| ----------- |
| wiringpi2.pinMode(1,1) // Set pin 1 to output |
| wiringpi2.digitalWrite(1,1) // Write 1 HIGH to pin 1 |
| wiringpi2.digitalRead(1) // Read pin 1 |
| |
| Bit shifting: |
| ------------- |
| wiringpi2.shiftOut(1,2,0,123) // Shift out 123 (b1110110, byte 0-255) to data pin 1, clock pin 2 |
| |
| Serial: |
| ------- |
| serial = wiringpi2.serialOpen('/dev/ttyAMA0',9600) // Requires device/baud and returns an ID |
| wiringpi2.serialPuts(serial,"hello") |
| wiringpi2.serialClose(serial) // Pass in ID |
