Is GPIO a peripheral?

Is GPIO a peripheral?

A peripheral is a part of a microcontroller that interfaces with the outside world. Examples of peripherals are GPIOs, I2C, SPI, UART, timers, and USB.

What is GPIO register?

The GPIO direction register (DIR) determines if a given GPIO pin is an input or an output. By default, all the GPIO pins are configured as input pins. When GPIO pins are configured as output pins, the GPIO output buffer drives the GPIO pin. At reset, GPIO pins default to input mode.

What is a GPIO peripheral?

The GPIO peripheral is used to configure the device IO ports, also called pins or pads. The IO pin (on the right) is the physical connection to a chip external ball, soldered on the PCB. The link between each GPIO pin and each ball of the package is given in the datasheet.

Is GPIO a register?

The GPIO direction register (DIR) specifies the direction of each GPIO signal. Logic 0 indicates the GPIO pin is configured as output, and logic 1 indicates input.

How are GPIO I / O resources represented in Windows?

A GPIO I/O resource is represented by a WDFIOTARGET handle that associates this resource with the specific GPIO controller driver that owns the underlying GPIO pin or pins.

What are GPIO pins and what do they do?

GPIO I/O pins, which are pins that are configured as data inputs or data outputs, are available as a new Windows resource type, GPIO I/O resources. In addition, GPIO interrupt pins, which are pins that are configured as interrupt request inputs, are available as ordinary Windows interrupt resources.

Is the SOC pin the same as the GPIO number?

A SOC pin has an alphanumeric name, the GPIO functionality usually has an alphanumeric name and in the SW APIs the GPIO is often referenced as a number. To make matters more complicated the SOC pin is then routed to the modules connector and gets an additional module pin name and number.

Which is GPIO pin has an alphanumeric name?

A SOC pin has an alphanumeric name, the GPIO functionality usually has an alphanumeric name and in the SW APIs the GPIO is often referenced as a number.
