ioio dev.0

An IOIO python module

This is very very alpha.

Basic Usage
------

import ioio
i = ioio.IOIO('/dev/ttyACM0')


Module layout:
------

ioio.IOIO : main class
Contains a board, interface, and protocol (see below)

ioio.boards : IOIO boards
Contains information about what a given board supports
Stores information about board state

ioio.interfaces : IOIO communication interfaces
Different ways to communicate with an IOIO board
Each must support:
connect/disconnect
read/write

ioio.protocols : IOIO protocols
Abstraction to (hopefully) support multiple IOIO protcol versions


TODO
------

Constants (pull [floating/low/high], etc...) where do they go?
State (where should it go?)

IOIO Functions
- Digital I/O
- Input
- Change Notify : (test: digital_in.py)
- Periodic Sampling : is this implemented in firmware?
- Output (test: led.py)
- Analog Input (test: analog_in.py)
- !! how do I store number of analog pins? for report_analog_in_status
- PWM Output (not working test: pwm.py) !! need to store state for this too
- Incap/Pulse Input (test: pulse_in.py)
- UART (test: uart.py)
- SPI
- TWI/I2C
- ICSP

Notes
------

Function uses: (all = config)
