Improve processing time by appending bits
instead of inserting them to the lists.

This fixes bug #1066.
|
|
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.
|
|
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 previously not decoding a bit for the first state change
to SHIFT-IR/-DR, which was incorrect.
|
|
|
|
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).
|
|
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 closes bug #156.

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.
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
Also, fix minor consistency issues, cosmetics, typos.

Don't handle them for now, will do this later.

Most importantly, both TDI and TDO are sampled at the rising TCK edge,
and only upon transitions from SHIFT-DR to SHIFT-DR and SHIFT-IR to SHIFT-IR
are we to save the TDI/TDO values (if I understood this correcly).
Also, start out in RUN-TEST/IDLE state for now. This is useful if you
have JTAG dumps which start "in the middle" somewhere, not in the
TEST-LOGIC-RESET state. For full dumps, the JTAG software usually issues
five TMS=1 cycles to force the JTAG state machine into TEST-LOGIC-RESET
anyway, so this works fine too.

This is unfinished, needs some more work.
