DigitalGlitchFilter¶

class wpilib.DigitalGlitchFilter[source]¶

Bases: wpilib.SensorBase

Class to enable glitch filtering on a set of digital inputs. This class will manage adding and removing digital inputs from a FPGA glitch filter. The filter lets the user configure the time that an input must remain high or low before it is classified as high or low.

add(input)[source]¶

Assigns the DigitalSource, Encoder, or Counter to this glitch filter.

Parameters:	input – The object to add

filterAllocated = [False, False, False]¶

free()[source]¶

getPeriodCycles()[source]¶

Gets the number of FPGA cycles that the input must hold steady to pass through this glitch filter.

Returns:	The number of cycles.

getPeriodNanoSeconds()[source]¶

Gets the number of nanoseconds that the input must hold steady to pass through this glitch filter.

Returns:	The number of nanoseconds.

mutex = <_thread.lock object>¶

remove(input)[source]¶: Removes this filter from the given input object

setPeriodCycles(fpga_cycles)[source]¶

Sets the number of FPGA cycles that the input must hold steady to pass through this glitch filter.

Parameters:	fpga_cycles – The number of FPGA cycles.

setPeriodNanoSeconds(nanoseconds)[source]¶

Sets the number of nanoseconds that the input must hold steady to pass through this glitch filter.

Parameters:	nanoseconds – The number of nanoseconds.
