Create the text representation of a bit string by means of the builtin
.format() method and an appropriate specifier. Drop the non-obvious
sequence of bin() and slice and zfill() calls.
|
|
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.

The 'fields' table of state and descriptions is not fully populated,
some slots are missing. Cope with lookup misses when unexpected input
data is not found in the table. Use different error text in annotations
for described but invalid states (the previous implementation used
"reserved / invalid"), and for states that are not described in the
table (introduce the "reserved / unknown" text for conditions that are
not covered by the decoder implementation).
The previous implementation missed the emission of some warnings. When a
"reserved / invalid" description was found, the subsequent exact match
for "reserved" failed and the warning was not emitted. Weaken the test
to emit warnings for either description that has "reserved" in it,
regardless of whether the text was found in the table or is not part of
the table at all.

Telling .wait() to "skip one sample" slightly obfuscates the intent of
getting the next samples while no condition applies. Explicitly pass no
condition arguments instead, to better reflect the purpose. Coincidently
these .wait() calls will execute in slightly less expensive code paths
in the common code.

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

The previous **kwargs some PDs had is not actually ever used, so drop it.

- 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).

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

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.
