2016-10-19uart: skip frames with invalid start bitsGerhard Sittig
When the start bit is not low at its sample point, then stop trying to interpret the remaining frame -- it's already known to be invalid, anyway. Wait for the next start bit instead, assuming that either the falling edge which started the inspection of the UART frame and its start bit was a spurious glitch or that the captured signal does not communicate at the decoder's configured bitrate.

2016-10-19uart: rework text formatting of communicated data values, plus nitsGerhard Sittig
Factor out the code which generates a textual representation for the numeric values that were communicated via UART bit patterns. Make the width of the output text depend on the number of bits in the UART frame (five to nine) instead of assuming bytes of exactly eight bits. Fix other minor issues while we are here: Nine bits result in a number range of 0 to 511 (not 512). ASCII codes 30 and 31 are non-printables. The previous implementation skipped a significant leading digit in the octal representation. Signed-off-by: Gerhard Sittig <gerhard.sittig@gmx.net>
2016-10-19uart: minor nit, rename the "databyte" variableGerhard Sittig
Given the generic nature of UART communication and the supported range for the data width, "byte" may be a misleading name for the numeric value that gets communicated in five to nine data bits. Rename the "databyte" variable to "datavalue". Signed-off-by: Gerhard Sittig <gerhard.sittig@gmx.net>

2016-09-24midi: Add support for complex MIDI message formats (inter-related).Chris
- 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
2016-09-24midi: chromatic_notes in list.py was off by 1 octaveChris
(ex: note 60 is middle C which is C4, not C3)
2016-09-24uart: Fix a bug in the output for stacked PDs.Uwe Hermann
The UART bit information was not transmitted correctly to stacked PDs if there was an overlap between RX and TX bytes in the data.
2016-09-04midi: Some annotation consistency changes.Uwe Hermann
2016-09-04Updates each annotation with multiple strings ranging from long, medium, and ↵Chris
short lengths
2016-08-26usb_power_delivery: Drop problematic exception in us2samples().Uwe Hermann
This causes an issue when running the sigrok-test test-cases, so drop it for now (the same check already exists in decode()). This fixes bug #758.
2016-08-23ssi32: Slightly more descriptive naming.Uwe Hermann
2016-08-23midi: Substantially improve decoding of MIDI messages.Chris Dreher
* 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().

2016-05-26Consistency renames of {ss,es}_ variables.Uwe Hermann
2016-05-25Move common/ directory into decoders/.Uwe Hermann
This simplifies cross-platform handling of the Python/decoder paths and module installation/dist a bit and also fixes bug #804.
2016-05-18Add decoder for em4305 RFID protocolBenjamin Larsson
2016-05-15Use consistent __init__() format across all PDs.Uwe Hermann
The previous **kwargs some PDs had is not actually ever used, so drop it.
2016-05-11usb_request: Drop hardcoded samplerate.Uwe Hermann
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.

2016-03-04Add an rgb_led_ws281x decoder.Uwe Hermann

2016-01-29uart: Optimize handling of samples when tx and rx are both idleDaniel Thompson
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.
2016-01-29arm_itm: Use objdump instead of addr2line.Petteri Aimonen
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.
