Device support
With WebIOPi 0.6+, you can use Serial/I2C/SPI/1-Wire devices directly from the REST API without writing macros.
WebIOPi drivers inherit from a common devices abstraction set (Temperature, Analog converter, GPIO Expander...) providing a consistent and unique set of function. Low level access to Serial, I2C and SPI is provided by lightweights classes available in the WebIOPi core without dependencies. Configuration is provided with the /etc/webiopi/config file. Devices and bus drivers can also be directly used in your Python script.

Device not listed ?
I cannot write a driver for all components, mainly because I don't have them, and I cannot buy everything. I could write drivers simply reading specs, but I will not be able to certify it work.
Submit your devices
Feel free to submit any component you use and/or would like to use with WebIOPi on the forum. Depending on demands, I may write the driver if I can have a sample.
How to help
If you know how the device work on it's low level interface, look on the source repository, starting with PCF8574, write your own and submit it. You can also provide me a sample so I can write the driver.
