# python-cec - libcec bindings for Python
`python-cec` allows you to control your TV, reciever and other CEC-compliant HDMI devices from a python script on a computer. Most computer graphics cards don't support CEC; you'll need a [Pulse-Eight USB-CEC adapter](http://www.pulse-eight.com/store/products/104-usb-hdmi-cec-adapter.aspx) or a Raspberry Pi (tested on Raspberry Pi 3 Model B Rev 1.2).
## Installing:
### Install dependencies
To build python-cec, you need version 1.6.1 or later of the libcec development libraries:
On Gentoo:
```
sudo emerge libcec
```
On OS X:
```
brew install libcec
```
Ubuntu, Debian and Raspbian:
```
sudo apt-get install libcec-dev build-essential python-dev
```
### Install from PIP
```
pip install cec
```
### Installing on Windows
You need to [build libcec](https://github.com/Pulse-Eight/libcec/blob/master/docs/README.windows.md) from source, because libcec installer doesn't provide *cec.lib* that is necessary for linking.
Then you just need to set up your paths, e.g.:
```
set INCLUDE=path_to_libcec\build\amd64\include
set LIB=path_to_libcec\build\amd64
```
## Getting Started
A simple example to turn your TV on:
```python
import cec
cec.init()
tv = cec.Device(cec.CECDEVICE_TV)
tv.power_on()
```
## API
```python
import cec
adapters = cec.list_adapters() # may be called before init()
cec.init() # use default adapter
cec.init(adapter) # use a specific adapter
cec.close() # not implemented yet
cec.add_callback(handler, events)
# the list of events is specified as a bitmask of the possible events:
cec.EVENT_LOG
cec.EVENT_KEYPRESS
cec.EVENT_COMMAND
cec.EVENT_CONFIG_CHANGE # not implemented yet
cec.EVENT_ALERT
cec.EVENT_MENU_CHANGED
cec.EVENT_ACTIVATED
cec.EVENT_ALL
# the callback will receive a varying number and type of arguments that are
# specific to the event. Contact me if you're interested in using specific
# callbacks
cec.remove_callback(handler, events)
devices = cec.list_devices()
class Device:
__init__(id)
is_on()
power_on()
standby()
address
physical_address
vendor
osd_string
cec_version
language
is_active()
set_av_input(input)
set_audio_input(input)
transmit(opcode, parameters)
cec.is_active_source(addr)
cec.set_active_source() # use default device type
cec.set_active_source(device_type) # use a specific device type
cec.set_inactive_source() # not implemented yet
cec.volume_up()
cec.volume_down()
cec.toggle_mute()
# TODO: audio status
cec.set_physical_address(addr)
cec.can_persist_config()
cec.persist_config()
cec.set_port(device, port)
# set arbitrary active source (in this case 2.0.0.0)
destination = cec.CECDEVICE_BROADCAST
opcode = cec.CEC_OPCODE_ACTIVE_SOURCE
parameters = b'\x20\x00'
cec.transmit(destination, opcode, parameters)
```
