Console

Introduction

The VEXcode CTE Console is displayed in the Monitor window within VEXcode. It allows you to display text, receive input, monitor variables and sensors, and format printed data in real time.

Note: The Console is only available when a Brain has been constructed with brain = Brain(), as all Console output is driven through methods on the Brain instance.

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

Below is a list of all methods:

Print — Interact with the console.

• print — Print text to the console.

• new_line — Move the console cursor position at the start of the next row down.

• clear — Clear all text from the console.

• set_print_color — Set the color text will display in for the console.

Monitor — Monitor a sensor’s or variable’s value during a project in VEXcode’s Monitor tab.

• monitor_variable — Add a predefined variable to the Monitor tab.

• monitor_sensor — Add a sensor to the Monitor tab.

Print

print

print prints values in the console using the current cursor position.

Usage:
brain.print(value, end)

Parameters	Description
value	The string (in quotations) or numbers to print to the Console.
end	Optional. By default, Python will add a new line after each print command. To print multiple values to the same line, use the end parameter.

# Print a greeting
brain.print("Hello there!")

new_line

new_line moves the cursor to the start of the row below the current position in the console.

Usage:
brain.new_line()

Parameters	Description
	This method has no parameters.

# Print on two lines
brain.print("Line 1")
brain.new_line()
brain.print("Line 2")

set_print_color

set_print_color sets the color used when printing text to the console.

Usage:
brain.set_print_color(color)

Parameters	Description
color	The color to print text with: BLACK BLUE GREEN RED

# Print in different colors
brain.print("Default text color")
brain.new_line()
brain.set_print_color(RED)
brain.print("Red text color")

clear

clear clears all text from the console.

Usage:
brain.clear()

Parameters	Description
	This method has no parameters.

# Clear the console after printing
brain.print("This will disappear...")
wait(2, SECONDS)
brain.clear()

Monitor

monitor_variable

monitor_variable adds a predefined variable to be monitored in the Monitor tab of VEXcode.

Usage:
monitor_variable(“variable”)

Parameters	Description
variable	The name of the predefined variable to monitor, given as a string.

# Monitor the amount of loops
global loops
monitor_variable("loops")

# Move in a square 3 times
for loops in range(12):
    arm.move_inc(100, 0, 0)
    arm.move_inc(0, 100, 0)
    arm.move_inc(-100, 0, 0)
    arm.move_inc(0, 100, 0)

actions = 0
# Monitor the amount of loops and actions
global loops, actions
monitor_variable("loops", "actions")

# Move in a square 3 times
for loops in range(12):
    arm.move_inc(100, 0, 0)
    arm.move_inc(0, 100, 0)
    arm.move_inc(-100, 0, 0)
    arm.move_inc(0, 100, 0)
    actions = actions + 4

monitor_sensor

monitor_sensor adds a sensor value to be monitored in the Monitor tab of VEXcode.

Usage:
monitor_sensor(“sensor”)

Parameters	Description
sensor	Which sensor to monitor, given as a string: arm.is_done arm.get_x arm.get_y arm.get_z arm.get_pitch arm.get_roll arm.get_yaw arm.can_arm_reach_to arm.can_arm_reach_inc arm.can_end_effector_reach_to arm.get_end_effector_reach_inc

# Monitor the x-axis in the Monitor tab
monitor_sensor("arm.get_x")
arm.move_to(40, 140, 210)

# Monitor the x-, y-, and z-axes in the Monitor tab
monitor_sensor("arm.get_x", "arm.get_y", "arm.get_z")
arm.move_inc(100, 0, 0)
arm.move_inc(0, 100, 0)
arm.move_inc(-100, 0, 0)
arm.move_inc(0, 100, 0)
