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.
|
|
This is not really relevant for stacked PDs currently (they can be used
unmodified with either PDv2 or PDv3 low-level decoders), but it'll allow
us to drop PDv2 support completely.

Remove the FSF postal address as it might change (it did in the past).
Reference the gnu.org website instead which is more stable.

- Handle "Running Status" where status byte can be omitted
- SysEx message can be terminated by status byte, not just EOX
- Handle SysReal messages that interrupt in-progress message transmission
- Identify and print garbage / truncated data
- Add 2 new annotations: text-sysreal-verbose and text-error

(ex: note 60 is middle C which is C4, not C3)

* Decode note names and percussion names (ex: 'G2', 'Tambourine').
* Decode instrument names and drum_kit names (ex: 'Flute', 'GS Orchestra Kit').
* Handle Polyphonic Pressure / Aftertouch (message 0xAn).
* Handle Program Change (message 0xCn).
* Handle Channel Pressure / Aftertouch (message 0xDn).
* Handle Channel Mode (message 0xBn mm where mm is 120 through 127).
* Handle System Common messages (message 0xF1 through 0xF6), including
full time code decoding.
* SysEx decoding now decodes the 1-3 byte manufacturer field, payload
is now displayed as hex.
* 'undefined' fields now display the value (ex: 'undefined 0xf4').
* Add 'MSB' and 'LSB' to many control_functions entries.
* Fix "trapped in state X" bug with handle_channel_msg_generic(),
though this might be dead code.
* Fix bug in sysex_manufacturer_ids; 1-byte manufacturers were not
tuples due to missing comma.
* Fix bug in SysEx decoding state machine; 0xF7 now sent to handle_sysex_msg().

The previous **kwargs some PDs had is not actually ever used, so drop it.
|
|
This will allow for much simpler code in stacked PDs.
Adapt stacked PDs to new API.
|
|
|
|
Anything else in the pd.py files doesn't have to be imported/exposed.
|
|
- 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.

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.
|
|
Older libsigrokdecode versions are no longer able to use the current
versions of the PDs (various changes in syntax etc).
|
|
|
|
Annotation entries also consist of a tuple, not a list.
|
|
|
|
The output type is now called OUTPUT_PYTHON, adapt all PDs to that.
|
|
|
|
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.

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

This better reflects what it is: a python object generated and
processed by python code.

|
This supports a certain number of MIDI messages already, but not yet all
of them. More will be added later.
