(

int32_t *

status

)

Gets the 3V3 rail current.

HAL_ResetUserCurrentFaults()

void HAL_ResetUserCurrentFaults

(

int32_t *

status

)

Resets the overcurrent fault counters for all user rails to 0.

HAL_SetBrownoutVoltage()

void HAL_SetBrownoutVoltage	(	double	voltage,
		int32_t *	status )

Set the voltage the roboRIO will brownout and disable all outputs.

Enables or disables the 3V3 rail.

Parameters

	enabled	whether the rail should be enabled
[out]	status	the error code, or 0 for success
