Analog Input

Read analog values from the 3-wire port on VEX EDR V5 Robot Brain

  • Library:
  • Simulink Coder Support Package for VEX EDR V5 Robot Brain / Sensors

  • Analog Input block


The Analog Input block reads analog values from the selected 3-wire port on VEX® EDR V5 Robot Brain. Use the block to measure the output of sensors (voltage), such as potentiometer, connected to the 3-wire port. The 12-bit sensor value has a range of 0 to 4095 that corresponds to an input voltage of 0V to 5V. You can use up to eight 3-wire ports on the VEX EDR V5 Robot Brain.

If you are using a 3-Wire Expander, specify the smart port on VEX EDR V5 Robot Brain to which the expander is connected.

Select the 3-wire port on the VEX EDR V5 Robot Brain from which you want to read the analog value.

Do not assign the same port to more than one Analog Input block within the same model.

Specify how often the block should read the values from the 3-wire port.
