	Improve robustness of some more protocol decoders. Few of them never checked for the availability of a sample rate in the first place, others checked for the presence of a spec but would not cope with a value of 0. Some checked the value only after processing it, which could result in runtime errors. This change is motivated by bug #1118.
2017-12-22	all decoders: introduce a reset() method	Gerhard Sittig
	Move initialization code of protocol decoders from the constructor to a new reset() helper method. The libsigrokdecode backend could run this method several times to clear the decoder's internal state, before new data from another acquisition gets fed to decode() calls.

2017-06-20	pwm: Fixup sample numbers for binary output	Gerhard Sittig
	Do reference the period's start and end sample numbers when the duty cycle is written to the binary output stream. The previous implementation inappropriately used the period counter instead.
2017-06-20	pwm: Eliminate more decoder "state"	Gerhard Sittig
	Move more items from the Python object's members to local variables of the decode() method, as they are used there exclusively. Mark a spot where the binary output references suspicious "sample numbers".
2017-06-20	pwm: Rephrase edge and period detection, eliminate internal state	Gerhard Sittig
	With the simplicity of PWM waveforms and the convenience of the v3 API, there is no need to maintain internal state. After the start of the first period was determined based on the input signal's polarity, any period is defined by just the next two edges, and the next period is immediately to follow.

2017-06-15	pwm: Simplify waiting for initial edge.	Uwe Hermann

2017-06-06	pwm: Convert to PD API version 3	Gerhard Sittig
	Have edges detected in common library code.
2017-01-07	license: remove FSF postal address from boiler plate license text	Gerhard Sittig
	Remove the FSF postal address as it might change (it did in the past). Reference the gnu.org website instead which is more stable.
2016-05-15	Use consistent __init__() format across all PDs.	Uwe Hermann
	The previous **kwargs some PDs had is not actually ever used, so drop it.
2016-04-20	pwm: Use self.{ss,es}_block for consistency across PDs.	Uwe Hermann

2015-12-24	Use self.out_binary naming consistently across all PDs.	Uwe Hermann

2015-12-24	Use a Python list (not tuple) for OUT_BINARY.	Uwe Hermann
	This is more consistent with annotation syntax and looks slightly better in most cases.
2015-09-15	jitter, pwm: Avoid Unicode string literals	Daniel Elstner
	It seems the Python we ship along our Windows binaries does not support u"..." strings, even though it's been a language feature since Python 2. Remove the "u" prefix to avoid a syntax error. Also, consistently use format "%.1f" at all scales. This fixes bug #569.

2014-11-02	pwm: Fix and rework	Sebastien Bourdelin
	Reworked in the algorithm: - Fixed the polarity setting - Taken in consideration the first transition - Using the 'None' state instead of -1 and 0 value - Simplify the algorithm and remove useless branches and variables - Avoid re-calculating the same thing more than once - Renamed a few variables for a better understanding - Duty cycle precision changed to floating value Otherwise: - Added a meta OUTPUT for the duty cycle average - Renamed the polarity option: 'polarity', 'active low/high' are well-understood terms. - Added comments Signed-off-by: Sebastien Bourdelin <sebastien.bourdelin@savoirfairelinux.com>
2014-10-17	Add a PWM decoder.	Uwe Hermann
