Linux Userspace GPIO Library
============================
* Export and Unexport GPIO pins
Current and planned features:
* Export and Unexport GPIO pins via sysfs
* Interrupt support (*)
* Hardware-neutral rewrite of NoccyLabs RaspIO
* Compatible with psr/logs LoggerInterface for logging
* Bit-banged SPI/I2C/1Wire
## Gpio
Without a mapper active, the GPIOs adressed are the direct exported GPIO numbers,
not necessarily in any logical order. Requesting `$gpio[22]` gives you `GPIO22`.
$gpio = new Gpio();
$gpio1 = $gpio[1];
### With a Mapper
With a mapper the pins are arranged logically starting at 0. For example, with
the WiringPi mapper, `$gpio[0]` would return `GPIO17` and so on. The `GpioPin#getPin()`
method will still return the actual GPIO (i.e. *17* rather than *0*).
$gpio = new Gpio();
$mapper = new WiringPiMapper(2);
$gpio->setMapper($mapper);
$gpio17 = $gpio[0];
## Interrupts

## Parallel addressing of pins

$pin = $gpio[$n]->setDirection("out");
$par->setGpioPin($n,$pin);
}
$par->write(0x55); // turn on 1, 3, 5, 7.
## Buses
*Not yet implemented*
$bus = new NoccyLabs\Gpio\Bus\SoftwareSpiBus;
$bus->mosi = $gpio[2];
$bus->sclk = $gpio[9];

Commands should include:
* `CLR` clears the display (`LcdDeviceInterface#clear()`)
* `LOC n m` moves the cursor to line n column m (0-indexed) (`LcdDeviceInterface#setCursorPos(n,m)`)
* `FONT n` loads the default font (0) or a custom font file (`LcdDeviceInterface#setFont()`)
* `OUT` Write text to the display (`LcdDeviceInterface#write()`)
* `CLR` - clears the display (`LcdDeviceInterface#clear()`)
* `LOC n m` - moves the cursor to line n column m (0-indexed) (`LcdDeviceInterface#setCursorPos(n,m)`)
* `FONT n` - loads the default font (0) or a custom font file (`LcdDeviceInterface#setFont()`)
* `OUT s` - Write text to the display (`LcdDeviceInterface#write()`)
* `MODE s` - Set text modes (`LcdDeviceInterface#setTextMode()`)
#### Modes
As supported:
* `+R`/`-R` - Set/clear inverse
* `+B`/`-B` - Set/clear bold
#### Fonts
#### Location and write
Location is maintained and incremented after writes.
