2020-01-11sdcard_sd: Use a Bit class to improve readability.Uwe Hermann
Usually we'd use namedtuple(), but in this case we need to retro-actively modify the items, so that's not possible.
2020-01-11sdcard_sd: Replace a hardcoded number for better readability.Uwe Hermann
2020-01-11sdcard_sd: Clarify some variable/argument names.Uwe Hermann
Differentiate cmd (e.g. 55 or CMD55) vs. cmd_pin (the value of the CMD pin).
2020-01-11sdcard_sd: Remove a list that needs manual maintenance.Uwe Hermann
Instead of checking if a command is in a fixed list/tuple (that needs to be manually updated every time a new command becomes supported), simply check if the respective handling method for the command exists. This fixes the bug of the CMD16 handler not being called, and will prevent similar bugs in the future.

2020-01-10spiflash: Use SrdIntEnum for annotation classes.Uwe Hermann
Also, automate construction of the Ann SrdIntEnum. This avoids having to remember to manually keep two lists in sync.
2020-01-10sdcard_spi: Use ternary operator where possible.Uwe Hermann
2020-01-10sdcard_spi: Use SrdIntEnum for annotation classes.Uwe Hermann
This also fixes incorrect annotation classes for bit, bit warning, and R1. Also, auto-generate some more parts of the annotation class listing.

cJTAG only has two wires/channels.

2020-01-09cjtag: Add cJTAG OSCAN1 decoder.Kongou Hikari
[Note: This is a commit from Kongou Hikari ("diodep" on GitHub) that was "rebased" by Uwe Hermann on top of the current libsigrokdecode mainline JTAG decoder. There are various reasons for this, including avoiding non-mainline or outdated decoder changes, as well as making it easily visible what the changes vs. the current JTAG decoder are, in case we later need to apply some changes to both decoders or in case both decoders might be merged later on. Minor cosmetic and naming changes were also squashed in (no functional changes, though).]
2020-01-08cjtag: Use an exact copy of the jtag PD as basis for cjtag.Uwe Hermann
2020-01-05spiflash: Don't use ambiguous annotation class names.Uwe Hermann
This is not technically a bug since (at least some) datasheets refer to this command as "Chip erase", it just happens to have two different command codes (0x60 and 0xc7). In order to not confuse users with two annotation classes with the same name, we'll call the second one "Chip erase 2" to match the "CE2" short name. This fixes bug #1482.
2020-01-05dmx512: stack DMX512 on top of UART and improve usabilityGerhard Sittig
It was unfortunate that the previous DMX512 decoder implementation re-invented UART decoder features and introduced new issues in the process. Automatic polarity detection is just impossible when the full set of valid DMX timings is to get supported. Sample numbers suffered from floating point rounding errors. Introduce a stacked decoder on top of UART which exclusively deals with DMX512 details, and transparently benefits from all available UART features (adjustable polarity, robust and correct sampling, data byte accumulation, BREAK detection while silencing false STOP violations). On one hand this requires users to specify the bitrate (250kbps), on the other hand it results in reliable operation for all captures that have become available so far. Provide Python output for stacked decoders which can process protocol extensions like RDM. Prepare the DMX512 decoder itself to handle simple cases of protocol extensions (start codes other than 0). Add support for additional constraint checks, emit warnings when user specified limits are violated: short BREAK, long MARK, long RESET to RESET and short BREAK to BREAK intervals. This shall speedup the identification of bus health issues (data loss or corruption) or improper controller timing. Also hide all-zero values by default, to make used channels visually stand out, and help users focus their attention. For special cases (like 16bit data, or zero being a valid set-point for the channels) users can enforce the display of all values. Provide an option to present byte values to users in the most appropriate format for the use case. This resolves bug #1442.
2020-01-05dmx512: remove previous implementation before replacing itGerhard Sittig
The existing DMX512 decoder implementation duplicates UART specific knowledge, and implements some of the redundant logic in ways which fail to interpret correct input data. See bug #1442 for details. This commit removes the previous decoder implementation before adding a more recent version, to gain a more readable history across that decoder replacement.
2020-01-04ps2: end data byte at rising clock edge of the stop bitGerhard Sittig
Data byte transmission is complete when the STOP bit was communicated. End the STOP bit at the rising CLOCK edge of the 11th bit time, do not rely on the host's clock inhibit after data transmission. This avoids the unexpected expansion of a STOP bit well into the next data byte. This fixes bug #1460, where absence of host activity after the first data byte loses synchronization to the input stream. Rephrase pin level sampling while we are here. Reflect that the clock line is used for .wait() conditions, but its level is not evaluated. Only data line levels get processed. Comment on the implementation's assumption of specific input data (the device as transmitter, host transmit may not be supported, or can result in unexpected output). Which may be acceptable yet maintainers need to remain aware.
