2015-10-06	usb_{signalling,packet}: Minor cosmetics.	Uwe Hermann

2015-10-06	usb_signalling: Track USB symbol width to compensate frequency errors	Stefan Brüns
	USB low/full speed allows for frequency tolerance of 1.5%/0.25%. At maximum packet size (sync + PID + data + CRC16) of 12 bytes/1027 bytes this amounts to 1.4 bits/20 bits, so the decoder has to lock to the actual symbol frequency to avoid any symbol misdetections. The signal is sampled twice, once at the symbol center and once at the expected edge position. Comparing the symbol at both positions gives an indication if the current bit width is too low or too high. Adjust accordingly.
2014-10-13	All PDs: Only import the 'Decoder' object.	Uwe Hermann
	Anything else in the pd.py files doesn't have to be imported/exposed.
2014-09-01	PD tests moved into the sigrok-test repo.	Uwe Hermann
	Drop them from the libsigrokdecode repository.
2014-08-14	pdtests: Check for SamplerateError in all PDs that emit it.	Uwe Hermann

2014-07-15	All PDs: Minor whitespace and consistency fixes.	Uwe Hermann
	- No newlines at the end of files. - No trailing ';' characters. - Comparison with None: Use 'is None' or 'is not None'. - Comparison with True/False: Use 'if cond:' or 'if not cond:'. - Various minor whitespace fixes.
2014-07-09	Various PDs: Throw SamplerateError instead of Exception.	Uwe Hermann
	Also, use the "if not self.samplerate" form, which catches both the case where self.samplerate is None, as well as the case where it is 0.
2014-07-09	All PDs: Drop unneeded exceptions.	Uwe Hermann
	In all current PDs it is not necessary to raise an exception upon invalid states (of the PD's state machine), since we can guarantee that no such invalid state can ever be reached in these PDs.
2014-04-15	All PDs: Bump api_version to 2.	Uwe Hermann
	Older libsigrokdecode versions are no longer able to use the current versions of the PDs (various changes in syntax etc).
2014-04-13	Rename 'probe' to 'channel' everywhere.	Uwe Hermann
	Variables of type 'struct srd_channel ' are consistently named 'pdch' to make them easily distinguishable from libsigrok's 'struct sr_channel ' variables that are consistently named 'ch'.
2014-03-18	usb_signalling: Make each symbol an annotation class.	Uwe Hermann

2014-03-18	usb_signalling: Provide better short/long annotations.	Uwe Hermann

2014-03-10	Probes, optional probes and annotations now take a tuple.	Bert Vermeulen
	Annotation entries also consist of a tuple, not a list.
2014-03-10	Remove unused probes and options	Bert Vermeulen

2014-03-10	Change PD options to be a tuple of dictionaries.	Bert Vermeulen
	Each option consists of a dictionary with the following keys: id The option id, which is passed in when setting a value. desc A description of the option, suitable for display. def The default value for this option. values (optional) If present, a tuple containing values the option may take. They must be of the same type as the default. Valid types for the options are UTF-8-encoded strings, integers, and floating point values.
2014-02-01	usb_signalling: Define annotation rows.	Uwe Hermann

2014-01-30	s/out_proto/out_python/.	Uwe Hermann
	The output type is now called OUTPUT_PYTHON, adapt all PDs to that.
2014-01-28	All PDs: Drop unneeded comments.	Uwe Hermann
	The single comment re-stating the PD's name / description / purpose in each pd.py file is not really needed, that info is available in the Decoder class' attributes already.
2014-01-28	All PDs: Improve/fix descriptions.	Uwe Hermann

2013-11-27	Automate protocol decoder installation.	Bert Vermeulen
	This automatically figures out the files to install for each protocol decoder, without involving autotools. All python files (filenames ending in .py) are always installed. If a protocol decoder requires installation of a non-python file, a small file called 'config' can be created in that protocol decoder's directory, with the following content: # comments are ok extra-install vendorlist.txt commands.txt
2013-11-15	Drop obsolete report() method.	Bert Vermeulen

2013-11-15	Use the new Decoder.register() API	Bert Vermeulen

2013-11-07	Rename inter-PD output type to SRD_OUTPUT_PYTHON	Bert Vermeulen
	This better reflects what it is: a python object generated and processed by python code.
2013-10-30	Receive samplerate via metadata(), not start()	Bert Vermeulen

2013-10-11	usb_signalling: Drop packet handling.	Uwe Hermann
	The usb_signalling PD should not care about packets, only symbols and bits. The new (fixed) usb_packet PD constructs packets out of individual bits now.
2013-10-11	usb_signalling: Document protocol output format.	Uwe Hermann
	Also, add missing output for some packet types.
2013-09-29	usb_signalling: Fix packet annotation.	Uwe Hermann

2013-09-29	usb_signalling: Fix EOP handling and annotation.	Uwe Hermann

2013-09-29	usb_signalling: Properly use different annotation types.	Uwe Hermann

2013-09-29	usb_signalling: Fix decode of individual bits.	Uwe Hermann
	After a Start of Packet (SOP) has been detected, "sample" the individual USB symbolѕ/bits in the middle of the respective bittime (depending on whether full-speed or low-speed signalling is used). This fixes various incorrectly decoded cases (bug #158).
2013-09-20	usb_signalling: Simplify symbols handling a bit.	Uwe Hermann

2013-09-20	usb_signalling: Refactor/simplify bitrate/bitwidth handling.	Uwe Hermann

2013-09-15	usb_signalling: Fix start/end sample numbers.	Uwe Hermann
	This makes the decoder suitable for GUI usage. This fixes bug #155.
2013-04-23	GPL headers: Use correct project name.	Uwe Hermann

2013-01-01	Small cosmetic/consistency fixes in the PDs.	Uwe Hermann

2012-11-24	All PDs: Name the files pd.py consistently.	Uwe Hermann
	The Python module name is determined by the directory name (e.g. dcf77), the *.py file names in that directory don't matter and can be kept consistent.
2012-07-11	srd: Performance improvements for various PDs.	Uwe Hermann
	Ignore/skip identical samples in most (low-level) PDs, as we're usually (but not necessarily always) only interested in pin changes. This yields a significant performance improvement for the PDs. The mechanism was already used in the 'i2s', 'jtag', and 'lpc' PDs, but not yet in all supported low-level decoders. The following PDs now also use this mechanism: 'dcf77', 'i2c', 'spi', 'uart', and 'usb_signalling'. Thanks Lars-Peter Clausen <lars@metafoo.de> for bringing this to our attention.
2012-06-21	srd: Split USB decoder in two PDs (which stack).	Uwe Hermann
	The 'usb_signalling' decoder just decodes symbols from D+/D- levels, handles bit stuffing and outputs the symbols and (potential) packets. The 'usb_protocol' decoder takes that output and tried to parse USB packets from it (SOF, SETUP, IN, OUT, DATA0, and so on). This is the base decoder on top of which various others will stack later on. The two new PDs are work in progress, so we still keep the old 'usb' PD around for a little while, until the two new ones are fully working and well-tested.
