The libsigrokdecode backend now passes metadata (e.g. samplerate) to all
PDs, stacked and non-stacked (see bug #664), so this interim solution is no
longer needed.
|
|
Currently only toplevel decoders receive the samplerate, thus stacked
decoders are not able to derive e.g. timestamps from the sample number.
This fixes bug #664.
|
|
|
|
|
|
|
|
These are used by the sdcard_spi and sdcard_sd decoders.
|
|
|
|
This is consistent with decoders/, conveniently allows for more than one
file per module, and also happens to avoid some import warnings.
|
|
|
|
|
|
(useful in GUIs for displaying more useful annotations at certain
zoom levels)
|
|
|
|
This new implementation supports all the features of the old decoder,
and additionally supports Clause 22 and 45.

The word "version" was accidentally replaced by "data" (sed).
|
|
Have the PD 'license' attribute match what the license header of the
respective pd.py file actually says.
|
|
This decoder handles the WS2812B protocol (and possibly WS2811).
Example dump already exists: led/ws281x/ws281x_4ch_5mhz.sr.

0.5.0 will be the next major, API-changing release. Bump now, so that
there is no confusion of tarball 0.4.0 and 0.5.0-git snapshots.
|
|
The last release (0.3.0) had the libtool version (current:revision:age)
set to 2:0:0. Since this release removes and changes interfaces, the new
version is 3:0:0.

This changes the library filename (e.g. on Linux) from
libsigrokdecode.so.2.0.0 to libsigrokdecode.so.3.0.0, the SONAME
(+symlink) becomes libsigrokdecode.so.3.

This fixes bug #739.

|
Re-enable the fast path for identical samples but only when both
pins are waiting for the start bit. For sparse data sets (I tested
UT61E capture log) the optimization results in a >4x decode
improvement.
|
|
This improves speed and fixes bug 564. Code is somewhat
of a copypaste from the arm_etm counterpart, but there
are enough differences that it is easier to keep separate
copy of the objdump parsing in each.

|
(for consistency with the other PDs)
|
|
|
|
This is more consistent with annotation syntax and looks slightly
better in most cases.
|
|
None of the PDs use this.
|
|
|
|
|
|
|
|
|
|
|
|
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.
This is also consistent with all the other PDs.
|
|
For consistency with other decoders, convert all the double quotes around
strings to single quotes.

This fixes bug #461.

PID decoding is normally done in the packet layer, but the signalling
layer has to switch behaviour on detection of an PREamble PID.
|
|
|
|
|
|
If the oldsym is not set to 'J' before entering IDLE state, the SOP
detection will never trigger
|
|
If a packet had any errors, the usb_signalling PD will not send an EOP
but an ERR message. Wait for the next SOP in both cases.
|
|
If a device or host did not receive a handshake 18 bit times after the
EOP, there was a transmission error and the host may repeat the
transmission
|
|
In automatic mode, the bus is assumed to be in IDLE state. After a
RESET, the bus state is checked again.
|
|
Resets are at least 10ms at the root hub downstream facing port and
2.5us at the device (root hub reset may be shortened by itermediate
hubs).
Keep-alive is a low-speed only signalling condition, as low-speed has no
SOFs to inhibit devices to enter suspend
|
|
Instead of centering the block around the sampleposition, which shows
some visual glitches due to rounding, use the edge positions already
known. Remove unused halfbit symbol.
|
|
Only SE0 and J are valid symbols during EOP
