# gpiosam

Fast GPIO Python driver for Atmel AT91SAM MCUs running Linux.


Thanks to good design of GPIO peripheral in SAM MCU is this script fully reentrant.


This driver need root privileges, because it use direct memory access.


Request python v2.7 or v3.x


## Installation

`sudo python setup.py install`

## Examples:

```python

import gpiosam

btn = gpiosam.Gpio('A', 27)

btn.enable = True

btn.output_mode = False

btn.pull_up = False

btn.pull_down = True

btn.input

  False

btn.input

  True

led = gpiosam.Gpio('A', 26)

led.enable = True

led.output_mode = True

led.output = True

led.output

  True

led.output = False

led.output

  False

led.output = not led.output

led.output

  True

```

## API:

### Gpio(port, pin)

initialize GPIO on *port* and *pin*

### Gpio.enable

property (rw) to enable or disable gpio

### Gpio.output_mode

property (rw) *true* to configure GPIO as output or *false* as input

### Gpio.open_drain

property (rw) to configure GPIO as open drain if is as outpu

### Gpio.pull_up

property (rw) control pull up resistors

### Gpio.pull_down

property (rw) control pull down resistors

### Gpio.output

property (rw) to control output on GPIO

### Gpio.input

property (r) to read GPIO value
