介绍#
The IQ (2nd gen) Brain can connect to either an IQ (2nd gen) or IQ (1st gen) Controller. Both controllers have two analog joysticks and multiple buttons that the Brain can use to detect movements and presses.
This page uses controller as the example controller name. Replace it with your own configured name as needed.
以下是所有可用方法的列表：
Actions — Turn controller configured actions on or off.
remote_control_code_enabled— Enable or disable controller configured actions.
Getters — Read button states and joystick positions.
.pressing— Returns whether the specified button is being pressed..position— Returns the position of the joystick’s specified axis.
Callback — Run code when buttons or joysticks change state.
.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..changed— Registers a function to be called when the joystick’s axis changes.
Constructors — Manually initialize and configure the controller.
Controller— Create a controller.
行动#
remote_control_code_enabled#
remote_control_code_enabled is a variable that can be set to a boolean that enables or disables controller configured actions from the Devices menu. The controller is enabled by default. It can be set to either of the following:
True— Enable controller configured actions.False— Disable controller configured actions.
Usage:
remote_control_code_enabled
# Drive forward or backward using the left joystick
remote_control_code_enabled = False
while True:
if controller.axisA.position() > 0:
drivetrain.drive(FORWARD)
elif controller.axisA.position() < 0:
drivetrain.drive(REVERSE)
# Press E Up to use the controller configured actions
elif controller.buttonEUp.pressing():
break
else:
drivetrain.stop()
wait(20, MSEC)
remote_control_code_enabled = True
吸气剂#
.pressing#
.pressing returns an integer indicating whether a specific button on the controller is currently being pressed. This method must be called on a specific button object, such as buttonEDown (see full list of button objects below).
1— The specified button is being pressed.0— The specified button is not being pressed.
