fbsd_gpio 0.2.0

How to use

The fbsd_gpio module expose two classes, GpioController and GpioPin

Use gpio controller unit 0 (/dev/gpioc0) and list all the pins name:

from fbsd_gpio import GpioController

gpioc = GpioController(0)
for pin in gpioc:
    print(pin)

Set pin 127 to output and logical value 1

from fbsd_gpio import GpioController, GPIO_VALUE_HIGH

gpioc = GpioController(0)
gpioc.pin_output(127)
# The two following lines are equivalent
gpioc.pin_set(127, GPIO_VALUE_HIGH)
gpioc.pin_high(127)

Alternativelly you can use the GpioPin class:

from fbsd_gpio import GpioPin, GPIO_VALUE_HIGH

pin = GpioPin(127, unit=0)
pin.ouput = True
# The following lines are equivalent
pin.set(GPIO_VALUE_HIGH)
pin.high()
pin(GPIO_VALUE_HIGH)

Or use the name of the pin directly:

from fbsd_gpio import GpioController, GPIO_VALUE_HIGH

gpioc = GpioController(0)
gpioc.gpioled0.output = True
# The three following lines are equivalent
gpioc.gpioled.set(GPIO_VALUE_HIGH)
gpioc.gpioled0.high()
gpioc.gpioled0(GPIO_VALUE_HIGH)

Get the value of a pin:

from fbsd_gpio import GpioPin

pin = GpioPin(128, unit=0)
if pin.input:
    print('Pin is input mode')
else
    print('Pin is output mode')
# The two following lines are equivalent
    value = pin.get()
    value = pin()

Toggle the value of a pin:

from fbsd_gpio import GpioPin

pin = GpioPin(128, unit=0)
pin.toggle()

Change the name of a pin:

from fbsd_gpio import GpioPin

pin = GpioPin(128, unit=0)
pin.name = 'green_led'
