Introducción

The VEX IQ (2nd gen) Brain Sensing category offers methods for interacting with the Brain’s buttons and connected battery.

This page uses brain as the example Brain name. Replace it with your own configured name as needed.

A continuación se muestra una lista de todos los métodos:

Actions — Interact with the VEX IQ (2nd gen) Buttons.

• pressed — Registers a function to be called when the specified button is pressed.

• released — Registers a function to be called when the specified button is released.

Getters — Return data from the buttons and battery.

• pressing — Returns whether the specified button is being pressed.

• capacity — Returns the remaining battery capacity.

• voltage — Returns the voltage of the battery.

• current — Returns the current drawn by the battery.

Constructors — Manually initialize the Brain.

• brain — Create a brain.

Comportamiento

pressed

pressed registers a function to be called when a specific button on the Brain is pressed. This method must be called on a specific button object, such as buttonCheck — (see full list of button objects below).

Uso:
Se puede usar uno de los tres objetos de botón disponibles con este método, como se muestra a continuación:

Botón	Dominio
buttonCheck	brain.buttonCheck.pressed(callback, arg) — The Check button
buttonLeft	brain.buttonLeft.pressed(callback, arg) — The Left button
buttonRight	brain.buttonRight.pressed(callback, arg) — The Right button

Parámetros	Descripción
callback	Una función que se define previamente para ejecutarse cuando se presiona el botón especificado.
arg	Opcional. Una tupla que contiene los argumentos que se pasarán a la función de devolución de llamada. Consulte Funciones con parámetros para obtener más información.

# Turn in a circle when the left button
# is pressed
def button_pressed():
    drivetrain.turn_for(RIGHT, 360, DEGREES)

brain.buttonLeft.pressed(button_pressed)

released

released registers a function to be called when a specific button on the Brain is released. This method must be called on a specific button object, such as buttonCheck — (see full list of button objects below).

Uso:
Se puede usar uno de los tres objetos de botón disponibles con este método, como se muestra a continuación:

Botón	Dominio
buttonCheck	brain.buttonCheck.released(callback, arg) — The Check button
buttonLeft	brain.buttonLeft.released(callback, arg) — The Left button
buttonRight	brain.buttonRight.released(callback, arg) — The Right button

Parámetros	Descripción
callback	Una función que se define previamente para ejecutarse cuando se suelta el botón especificado.
arg	Opcional. Una tupla que contiene los argumentos que se pasarán a la función de devolución de llamada. Consulte Funciones con parámetros para obtener más información.

# Turn in a circle when the left button
# is released
def button_released():
    drivetrain.turn_for(LEFT, 360, DEGREES)

brain.buttonLeft.released(button_released)

Captadores

pressing

pressing returns a Boolean indicating whether a specific button on the Brain is currently being pressed. This method must be called on a specific button object, such as buttonCheck (see full list of button objects below).

• True — The specified button is being pressed.

• False — The specified button is not being pressed.

Uso:
Se puede usar uno de los tres objetos de botón disponibles con este método, como se muestra a continuación:

Botón	Dominio
buttonCheck	brain.buttonCheck.pressing() — The Check button
buttonLeft	brain.buttonLeft.pressing() — The Left button
buttonRight	brain.buttonRight.pressing() — The Right button

Parámetros	Descripción
	Este método no tiene parámetros.

# Turn when the check button is pressed
while True:
    if brain.buttonCheck.pressing():
        drivetrain.turn(RIGHT)
    else:
        drivetrain.stop()

capacity

capacity returns the remaining capacity of the battery as a percentage.

Usage:
brain.battery.capacity()

Parámetros	Descripción
	Este método no tiene parámetros.

# Display the current battery capacity
brain.screen.print(brain.battery.capacity())

voltage

voltage returns the voltage of the battery as a float.

Usage:
brain.battery.voltage(units)

Parámetros	Descripción
units	Optional. The unit that represents the voltage: MV (default) — Millivolts VOLT

# Display the current voltage of the battery
brain.screen.print(brain.battery.voltage())

current

current returns the current drawn from the battery in milliamps as a float.

Usage:
brain.battery.current()

Parámetros	Descripción
	Este método no tiene parámetros.

# Display the current of the battery
brain.screen.print(brain.battery.current())

Constructores

Brain

Brain creates an object of the brain class.

Usage:
brain = Brain()

Parámetros	Descripción
	Este método no tiene parámetros.

brain = Brain()

# Turn when the check button is pressed
while True:
    if brain.buttonCheck.pressing():
        drivetrain.turn(RIGHT)
    else:
        drivetrain.stop()
