Battery Read

Read voltage of battery

  • Library:
  • Simulink Support Package for Arduino Hardware / Arduino Motor Carrier

  • Battery Read block

Description

The Battery Read block reads the voltage of the battery connected to an MKR Motor Carrier. The block outputs the voltage as a 12-bit digital value ranging between 0 and 4095. An output of 0 corresponds to minimum volts and an output of 4095 corresponds to maximum volts on an analog pin connected to the battery.

If you simulate a model that contains the Battery Read block without connecting the hardware, the block outputs zeroes. For more information, see Block Produces Zeros or Does Nothing in Simulation.

Supported Hardware

You can use the Battery Read block only with MKR and Nano 33 IoT boards.

The port outputs the voltage of the battery connected to the MKR Motor Carrier. The block outputs the voltage as a 12-bit digital value ranging between 0 and 4095. An output of 0 corresponds to the minimum volts, and an output of 4095 corresponds to the maximum volts on an analog pin connected to the battery.

Data Types: uint16

Parameters

Specify how often the block reads the voltage of the battery, in seconds. When you specify this parameter as -1, Simulink® determines the best sample time for the block based on the block context within the model.
