Understanding Button and Joystick Names on EXP Controller

VEXcode EXP can access the data from an EXP Controller by referencing the buttons and joystick axes by their names.

Position and Names of Buttons and Joysticks

The image below shows the button and joystick names and locations. Buttons return values of:

  • 1 - Pressed
  • 0 - Not Pressed / Released


Each joystick axis returns a value between -100 to +100, and returns a value of zero when centered.

Blocks that include Controller Buttons and Joysticks

When programming in VEXcode EXP, understanding the button and joystick names, as well as their position on the Controller, helps determine which block should be used. 

For more information on using the Controller, see articles in the Controller section of the STEM Library.
