libsigrok

Hardware support

• Clean up device-specific globals in hardware drivers, to properly permit multiple devices per driver: fx2lafw, zeroplus-logic-cube, others(?)
• Asix SIGMA driver: support multiple devices properly (currently only one is supported).
• Chronovu LA8/LA16 driver: support multiple devices properly (currently only one is supported).

Input/output modules

• Scanalogic (Uwe Hermann).
• Rigol
  • File format:ROF: Used by DP800 series power supplies
  • RAF: Used by DG1000Z, DG4000, and DG5000 series signal generators. See DG100Z User Guide page 2-75, also this post at eevblog.

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

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().

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 support
  • Add signal v-scale control (Volts/div).
  • Add interpolation (cosine? sinc? some kind of interpolation filter?)
• Add support for other open/import file formats
• Add signal overview
• Paint speed profiling information.
• Code documentation
• Transition coding
• Store more config options with QSettings
