What does GPIO mean?

GPIO is the short form for General Purpose Input/Output. It is a type of digital pin fitted inside an integrated circuit or an electronic circuit board. The pin, as the name suggests, can be used both as an input and as output and can be handled by the user itself during the runtime. 

Generally, there is no predefined purpose for GPIO and they are unused by default. When they are used, the designer defines their purpose and behavior according to the specific case.

Features of GPIOs

• It supports both hardware and software connections
• It supports digital, analog and bidirectional signal types
• Placing and routing signals automatically to and from the GPIOs
• The quick setup process of GPIO parameters
• Provides access to external signals through the physical output pin
• Allows the electrical characteristics choosing for more than one pins

Modes in GPIOs

GPIOs run in three primary running modes. These are:

1. GPIO Input – the default mode where the input from the connected device is received through the GPIO pin.
2. GPIO Output – the data is transferred to the device from the beacon through the GPIO pins in the output mode.
3. UART interface – this mode allows custom advertising packets for the beacon.

Advantages of GPIOs

There are a variety of reasons GPIOs are used so much such as:

• The pins can be easily enabled or disabled.
• They can be easily configured to be used as input or output pins depending upon the usage.
• Output pins values can be read and written easily.
• Input pins can play the role of interrupt lines which can signal to the primary board signifying that it requires attention.
• Input pins are readable in nature where 1 signifies high voltage and 0 signifies low voltage.
