- org.deepjava.flink.subdevices.FlinkPPWA

All Implemented Interfaces:

FlinkDefinitions
```
public class FlinkPPWA
extends Object
implements FlinkDefinitions
```
The flink PPWA subdevice realizes a PPWA function (pulse and period measurement) within a flink device. It offers several channels. Each channel has its own period and duty cycle.

  - FlinkPPWA
```
public FlinkPPWA(FlinkSubDevice dev)
```
    Creates a PPWA subdevice.
    
    Parameters:
    
    dev - handle to the subdevice
- Method Detail
  - getBaseClock
```
public int getBaseClock()
```
    Returns the base clock of the underlying hardware counter.
    
    Returns:
    
    the base clock in Hz.
  - getPeriod
```
public int getPeriod(int channel)
```
    Reads the period of a single channel. Channel number must be 0 <= channel < nof available channels. Period setting is in multiple of the base clock, @see getBaseClock().
    
    Parameters:
    
    channel - channel number
    
    Returns:
    
    multiple of base clock
  - getHighTime
```
public int getHighTime(int channel)
```
    Reads the hightime of a single channel. Channel number must be 0 <= channel < nof available channels. Hightime setting is in multiple of the base clock, @see getBaseClock().
    
    Parameters:
    
    channel - channel number
    
    Returns:
    
    multiple of base clock
