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 avoids some boilerplate in the decode() method itself.
|
|
Rewrite of the 1-Wire link decoder.
Existing outputs are kept and new warnings are added.
Instead of sampling at fixed user defined time, time ranges as
specified by the "Book of iButton Standards" are used.
The user does not have to tweak the timing values anymore.
Overdrive speed is detected automatically.
This fixes bugs #666 and #926.

|
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.
|
|
The code was trying to emit annotations before
self.register(srd.OUTPUT_ANN) was run.
This fixes bug #357.

- 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.

(Consistently use single-quotes for all Python strings everywhere)
|
|
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.
|
|
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.
|
|
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.

|
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.
|
|
|
|
|
|
|
|
This needs a few more fixes later, but it's a start.
|
|
|
|
This also simplifies the PD code a bit.
|
|
This fixes bug #147.

|
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.
