      • "HAL_GetUserVoltage3V3"

    • getUserCurrent3V3

      public static double getUserCurrent3V3()
      Gets the 3V3 rail current.
      Returns:
      the 3V3 rail current (amps)
      See Also:
      • "HAL_GetUserCurrent3V3"

    • setUserEnabled3V3

      public static void setUserEnabled3V3(boolean enabled)
      Enables or disables the 3V3 rail.
      Parameters:
      enabled - whether the rail should be enabled

    • getUserActive3V3

      public static boolean getUserActive3V3()
      Gets the active state of the 3V3 rail.
      Returns:
      true if the rail is active, otherwise false
      See Also:
      • "HAL_GetUserActive3V3"

    • getUserCurrentFaults3V3

      public static int getUserCurrentFaults3V3()
      Gets the fault count for the 3V3 rail.
      Returns:
      the number of 3V3 fault counts
      See Also:
      • "HAL_GetUserCurrentFaults3V3"

    • resetUserCurrentFaults

      public static void resetUserCurrentFaults()
      Resets the overcurrent fault counters for all user rails to 0.

    • setBrownoutVoltage

      public static void setBrownoutVoltage(double voltage)
      Set the voltage the roboRIO will brownout and disable all outputs.

      Note that this only does anything on the roboRIO 2. On the roboRIO it is a no-op.

      Parameters:
      voltage - The brownout voltage
      See Also:
      • "HAL_SetBrownoutVoltage"

    • getBrownoutVoltage

      public static double getBrownoutVoltage()
      Get the current brownout voltage setting.
      Returns:
      The brownout voltage
      See Also:
      • "HAL_GetBrownoutVoltage"

    • getCPUTemp

      public static double getCPUTemp()
      Get the current CPU temperature in degrees Celsius.
      Returns:
      current CPU temperature in degrees Celsius
