Digital

Python Library for Digital IO Ports.

Python Library

Turta_Digital library is responsible for setting and getting GPIO pin states of the digital ports.

Initialization

Add the following statement to the top of your Python code.

from turta_iothat3 import Turta_Digital

Then, create an instance of the DigitalPort class.

digital = Turta_Digital.DigitalPort(True, True, True, True)

Now you're ready to access the library by calling its instance.

Initialization Parameters

DigitalPort

Initiates the GPIO pins.

Turta_Digital.DigitalPort(d1In, d2In, d3In, d4In)

• Parameters

  • Bool d1In: Pin 1 direction. (True for input, False for output, True is default.)

  • Bool d2In: Pin 2 direction. (True for input, False for output, True is default)

  • Bool d3In: Pin 3 direction. (True for input, False for output, True is default)

  • Bool d4In: Pin 4 direction. (True for input, False for output, True is default)

Basic Members

Read Input Pin

Reads the digital input.

read(ch)

• Parameters

  • Byte ch: IO Channel. (1 to 4.)

• Returns

  • Bool: Pin input state. (True for high, False for low.)

Write Output Pin

Sets the digital output.

write(ch, st)

• Parameters

  • Byte ch: IO Channel. (1 to 4.)

  • Bool st: Pin output state. (True for high, False for low.)

• Returns

  • None

Toggle Output Pin

Inverts the digital output.

toggle(ch)

• Parameters

  • Byte ch: IO Channel. (1 to 4.)

• Returns

  • None

Finalizer

When exiting from the program, the library releases the GPIO pins.
