libsigrok
Hardware support
- Clean up device-specific globals in hardware drivers, to properly permit multiple devices per driver: fx2lafw, zeroplus-logic-cube, others(?)
- Chronovu LA8/LA16 driver: support multiple devices properly (currently only one is supported).
Input modules
- Add OLS input module support.
- Add gnuplot input module support (Uwe Hermann).
Miscellaneous
- Check all public API calls to see whether they need an sr_context parameter.
- sr_errno:
- Most functions should return SR_OK or SR_ERR_* (same for SRD_OK etc).
- Most backend functions return status as an integer, which is SR_OK if all went well, or SR_ERR_* if an error occurred.
- However, there is no way to pass any information back as to what went wrong — and this is important for user-friendliness.
- Perhaps an error code is not enough; maybe something like sigrok_errno(errorcode, "unsupported device") is better.
- Support specifying the firmware directory at runtime.
libsigrokdecode
Major features
- Add high-precision timer to runtc
- Add annotation mime types
- Add annotation metadata (type/value/unit) to allow clients to format the value as the user desires (ASCII/dec/hex/bin/whatever)
Other
- Test/implement support for multiple outputs of one PD, and stacking different additional PDs on those outputs.
- Test/implement multiple inputs support.
- Python exception handling in libsrd: add full traceback support with srd_dbg().
sigrok-cli
fx2lafw
- Analog sampling: 1-channel, 2-channel, voltage meter
- Trigger pin
- Clock input
- Clock output
- Frequency/pulse counter
- Signal generator
- Fix power consumption during enumeration.
- Non-LP FX2's consume more than 100mA during enumeration. This is outside of the USB specification
- Official workaround is to enumerate first as full-speed, then as high-speed. This is overkill for sigrok.
- Investigate putting the CPU to sleep (except for processing interrupts) until enumerated.
PulseView
- Deduplicate property setting functionality between SamplingBar and DeviceOptions - make SamplingBar a properties container
- Analog interpolation (cosine? sinc? some kind of interpolation filter?)
- Signal overview
- Transition coding
sigrok-meter
- Make the list of measurements look nicer without using too much additional space.
- Add graphs.
- PyQtGraph looks like a nice graphing library.
- Works with PyQt and PySide.
- Pure python, easy to install.
- Few dependencies: scipy is not required any more in the upcoming version 0.9.9, numpy is already a dependency of the python bindings.
- From looking at the examples, it seems more than fast enough for our requirements.
- Pass all samples (not only the most recent one) to the GUI thread and store them there.
- The packet payload object is currently not thread save.
- PyQtGraph looks like a nice graphing library.
