Introducción #

The Timer in VEX IQ (2nd Gen) allows you to track elapsed time and perform actions based on time intervals. With various methods for time management, you can create precise and timed operations within your program.

Below is a list of all methods:

Methods – Control and interact with the Brain’s timer.

tiempo – Devuelve el tiempo transcurrido desde que se inició el proyecto.
clear – Resets the timer to zero.
system – Returns the number of milliseconds the Brain has been powered on.
system_high_res – Returns the number of microseconds the Brain has been powered on.
evento – Llama a una función después de una cantidad específica de milisegundos, con argumentos opcionales.

Constructor – Create additional timers.

Timer – Creates an additional timer.

tiempo #

time devuelve el tiempo transcurrido actual del temporizador en las unidades especificadas: un entero para MSEC o un flotante para SECONDS.

Usage:
brain.timer.time(units)

Parámetros	Descripción
`unidades`	Las unidades de tiempo son milisegundos «MSEC» (predeterminado) o «SEGUNDOS».

# Display the current time on the timer
while True:
    brain.screen.set_cursor(1, 1)
    brain.screen.clear_screen()
    brain.screen.print(brain.timer.time(SECONDS))
    wait(50, MSEC)

clear #

clear sets the timer to zero.

Usage:
brain.timer.clear()

Parámetros	Descripción
	Este método no tiene parámetros.

# Reset the timer when a button is pressed
while True:
    brain.screen.set_cursor(1, 1)
    brain.screen.clear_screen()
    brain.screen.print(brain.timer.time(SECONDS))
    wait(50, MSEC)
    if brain.buttonCheck.pressing():
        brain.timer.clear()

system #

system returns the number of milliseconds the Brain has been powered on.

Usage:
brain.timer.system()

Parámetros	Descripción
	Este método no tiene parámetros.

# Display the time the brain has been on in milliseconds
while True:
    brain.screen.set_cursor(1, 1)
    brain.screen.clear_screen()
    brain.screen.print(brain.timer.system())
    brain.screen.print(" MSEC")
    wait(50, MSEC)

system_high_res #

system_high_res returns the number of microseconds the Brain has been powered on.

Usage:
brain.timer.system_high_res()

Parámetros	Descripción
	Este método no tiene parámetros.

# Display the time the brain has been on in microseconds
while True:
    brain.screen.set_cursor(1, 1)
    brain.screen.clear_screen()
    brain.screen.print(brain.timer.system_high_res())
    wait(50, MSEC)

evento #

event llama a una función después de una cantidad de tiempo especificada.

Usage:
brain.timer.event(callback, delay, arg)

Parámetros	Descripción
`devolución de llamada`	Una función a ejecutar cuando ocurre el evento del temporizador.
`retraso`	El retraso antes de que se llame a la función, en milisegundos.
`arg`	Optional. A tuple containing arguments to pass to the callback function. See Functions with Parameters for more information.

# Define a function timer_event
def timer_event():
    drivetrain.drive_for(FORWARD, 200, MM)

# Drive forward after a 5000 millisecond delay
brain.timer.event(timer_event, 5000)

Constructors #

Constructors are used to manually create Timer objects, which are necessary for creating any additional timers besides brain.timer.

For the examples below, the configured Timer will be named timer_1 and will be used in all subsequent examples throughout this API documentation when referring to Timer class methods.

Minutero #

Timer creates a new timer. A Timer object will immediately begin counting the moment it is created and will work with all brain.timer methods.

Uso:
Timer()

Parámetros	Descripción
	Este constructor no tiene parámetros.

wait(2, SECONDS)
timer_1 = Timer()
while True:
    brain.screen.clear_screen()
    brain.screen.set_cursor(1, 1)
    brain.screen.print("Brain: ")
    brain.screen.print(brain.timer.time(SECONDS))
    brain.screen.next_row()
    brain.screen.print("timer_1: ")
    brain.screen.print(timer_1.time(SECONDS))
    wait(15, MSEC)
