Counter Functions¶
-
py4syn.utils.counter.createCounter(mnemonic, device, channel=None, monitor=False, factor=1)[source]¶ Add a countable to the counterDB dictionary
Parameters: - mnemonic : string
Mnemonic of the counter
- device : ICountable
The device that handles this counter and implements ICountable interface
- channel : int
Specify where usable the channel index for this counter
- monitor : bool
If monitor is set to True the process will be by counts and not by time
- factor : int
Specify the factor to be used when reading the counter value
Examples
>>> scaler = Scaler("SOL:SCALER", 10, "scaler1") # Creates an EPICS Scaler >>> scalerSIM = SimCountable("ANY:PV:HERE", "simMnemonic") >>> createCounter("seconds", scaler, 1, factor=1e+7) # Create a channel using the real >>> # scaler, channel number 1 and a factor. >>> createCounter("det", scaler, 3) >>> createCounter("mon", scaler, 10, monitor=True) # Create a channel that will act as a monitor >>> createCounter("cyberSim", scalerSIM, 2) >>> ct(10000) # Start a count process until 10000 counts in the monitor >>> # and show the results for each channel at the end. >>> counts = ctr(2, use_monitor=False) # Start a count process with 2 seconds >>> # of integration time. Returns the counts as a map. >>> print("Counts on det: ", counts['det'])

py4syn.utils.counter.ct(t=1, use_monitor=False)[source]¶ Count all counters available using the given time
Parameters: - t : double
Time of Preset to be used
- use_monitor : bool
If monitor is set to True the process will be by counts and not by time
-
py4syn.utils.counter.disableCounter(mne)[source]¶ Disable an specific counter
Parameters: - mne : string
The counter mnemonic
