2018-11-20i2s: Fix 2 issues.Weixiao Zhang
1. WS = 0, Left Channel; WS = 1, Right Channel 2. Data start and end at falling edge of SCK
2018-02-13i2s: make samplerate meta data optionalGerhard Sittig
Only emit sound samplerate information when an input stream sample rate was specified. Cope with the absence of a sample rate for the input stream. Decoding is still possible, it's just that no timing information is available.
2017-12-22all decoders: introduce a reset() methodGerhard 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.
2017-12-09i2s: Fix unportable use of struct.packMarcus Comstedt
Using the format string 'I' with the default (implied) prefix '@' results in both word size and endianness being platform dependent. In this case standard size (32 bits) and little endianness is required, so the prefix '<' needs to be used.
2017-11-11i2s: Set file size to 4GbJoel Holdsworth
2017-11-11i2s: Make 32-bit wav filesJoel Holdsworth
2017-01-07license: remove FSF postal address from boiler plate license textGerhard 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.
2016-12-07i2s: Convert to PD API version 3.Uwe Hermann
2016-05-15Use consistent __init__() format across all PDs.Uwe Hermann
The previous **kwargs some PDs had is not actually ever used, so drop it.
2015-12-24Use self.out_binary naming consistently across all PDs.Uwe Hermann
2015-12-24Use a Python list (not tuple) for OUT_BINARY.Uwe Hermann
This is more consistent with annotation syntax and looks slightly better in most cases.
2014-10-13All PDs: More consistent names for ss/es variables.Uwe Hermann
Use self.ss/self.es, or if there's a need to differentiate them a bit more, use self.ss_<suffix>/self.es_<suffix> consistently. Also, drop some unused variables.
2014-10-13All PDs: Only import the 'Decoder' object.Uwe Hermann
Anything else in the pd.py files doesn't have to be imported/exposed.
2014-09-01PD tests moved into the sigrok-test repo.Uwe Hermann
Drop them from the libsigrokdecode repository.
2014-08-14pdtests: Check for SamplerateError in all PDs that emit it.Uwe Hermann
2014-07-15All 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.
2014-07-09Various 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.
2014-04-15All 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).
2014-04-13Rename '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'.
2014-03-10Probes, optional probes and annotations now take a tuple.Bert Vermeulen
Annotation entries also consist of a tuple, not a list.
2014-03-10Remove unused probes and optionsBert Vermeulen
2014-01-30s/out_proto/out_python/.Uwe Hermann
The output type is now called OUTPUT_PYTHON, adapt all PDs to that.
2014-01-28All 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.
2014-01-28All PDs: Improve/fix descriptions.Uwe Hermann
2014-01-23i2s: Add WAV dump support, drop obsolete 'i2s_dump' PD.Uwe Hermann
The functionality of the preliminary 'i2s_dump' PD is now available in the proper 'i2s' PD, via the OUTPUT_BINARY mechanism that frontends can use to dump decoded data (in various formats) to a file, or pipe it into other applications, and so on. Old sigrok-cli example usage: $ sigrok-cli -i 2ch-16bit-16khz.sr \ -P i2s:sck=0:ws=1:sd=2,i2s_dump:filename=foo.wav $ aplay foo.wav New sigrok-cli example usage: $ sigrok-cli -i 2ch-16bit-16khz.sr \ -P i2s:sck=0:ws=1:sd=2 -B i2s=wav > foo.wav $ aplay foo.wav New sigrok-cli example usage (piping into other applications): $ sigrok-cli -i 2ch-16bit-16khz.sr \ -P i2s:sck=0:ws=1:sd=2 -B i2s=wav | aplay -
2013-12-28i2s: Fix typo.Uwe Hermann
2013-12-28i2s: Replace I2S with I²SJoel Holdsworth
2013-11-27Automate 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
2013-11-15Use the new Decoder.register() APIBert Vermeulen
2013-11-07Rename inter-PD output type to SRD_OUTPUT_PYTHONBert Vermeulen
This better reflects what it is: a python object generated and processed by python code.
2013-10-30Receive samplerate via metadata(), not start()Bert Vermeulen
2013-10-08i2s: Add shorter and longer annotations for GUI use.Uwe Hermann
This fixes (the remaining parts of) bug #162.
2013-10-08i2s: Define/use common proto out format.Uwe Hermann
2013-10-08i2s: Add helper methods for annotation/proto output.Uwe Hermann
2013-10-08i2s: Use annotation types.Uwe Hermann
This fixes parts of bug #162.
2013-09-03i2s: Fixed annotation sample numbersJoel Holdsworth
2013-04-23GPL headers: Use correct project name.Uwe Hermann
2012-11-24All 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.
2012-05-09srd: Add usable one-liner descriptions for all PDs.Uwe Hermann
2012-05-08srd: Remove TODOs from annotation format names.Uwe Hermann
Also, fix minor consistency issues, cosmetics, typos.
