== sigrok 0.1 release-critical issues ==

sigrok 0.1 comprises only sigrok-cli, i.e. GUI and protocol decoders are '''not''' part of the release.

* Ensure that segfaults are rare / non-existing in CLI. Use code reviews and valgrind or similar to check.
* Windows port
** At least a working sigrok-cli with the demo driver is required.
** Implement anykey.c replacement.
* Mac OS X port: Make sure sigrok-cli builds, and at least the demo driver works.
* <s>Update sigrok-cli man page.</s>
** <s>Document --continuous option.</s>
** <s>Document --input-file option.</s>
** <s>Add examples of basic usage with -o samplerate.</s>
* <s>Make sure all output modules handle unknown DF types gracefully (problem in event handlers)</s>
* Temporarily remove non-functional options from CLI
** PDs
** session saving/loading
* <s>cli: pack list of drivers, modules etc into one option which displays all of those. Update manpage accordingly.</s>
* libsigrok, libsigrokdecode: Proper shared libs setup and version numbers to be able to handle API/ABI compatibility issues sanely later.
* Ensure that "make distcheck" works fine, and that you can build sigrok using that generated tarball (i.e. no missing files etc).
* Make sure all output formats work OK and there are no segfaults.
** Test that they're not corrupted by stray errors printed on stdout instead of stderr.
** Test all of the above without SIGROK_DEBUG, with SIGROK_DEBUG=1, and SIGROK_DEBUG=2.
* Make sure all combinations of --enable-*/--disable-* options works for configure.
** There are possible issues if no libusb-device is enabled (e.g. only OLS or only demo).
** There may be issue if none of the drivers is enabled, print useful error in that case(?)
* libsigrok.h/libsigrokdecode.h: Only list public API functions.
** Prefix all public functions with sigrok_ or sigrokdecode_.
** Most functions should return SIGROK_OK or SIGROK_ERR_* (same for LIBSIGROK_OK etc). Some may return a string or NULL upon error, etc.

== sigrok 0.2 features ==

* support OLS file format input and output (https://github.com/jawi/ols/wiki/OLS-data-file-format)
* cli: fix save session, implement load session

== General ==

* sigrok uses uint64_t as an internal datatype to represent a sample, limiting the number of probes on supported hardware to 64. But high-end logic analyzers can have hundreds of probes. A solution would be to switch to either a roll-our-own byte array type, or use [http://gmplib.org/ GMP]. In any case, the overhead of switching over shouldn't be too bad: the filter code and frontend datafeed callback functions will need to use it, but hardware drivers should have enough with a couple of lightweight wrappers.

== libsigrok ==

* Fix/workaround libusb 1.0 [[Windows]] port issues:
** Device renumeration not yet supported (needed for FX2 based LAs)
** File descriptor / socket based polling not supported in Windows. Workaround (short-term): Use a thread in sigrok.
* Session loading from file.
* sigrok_errno:
** Most backend functions return status as an integer, which is SIGROK_OK if all went well, or SIGROK_ERR_* and similar 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.
** Both the cmdline and GUI interfaces need this, really, so it should be a backend library thing.
* Make sure all optional components are really optional in the build system:
** Only require Python if the users wants protocol decoders, the rest should also build/compile/run fine without Python installed.
** ...
* Add output for latex package [http://www.ctan.org/tex-archive/graphics/pgf/contrib/tikz-timing tikz-timing]

== Hardware drivers ==

* Clean up device-specific globals in hardware drivers, to properly permit multiple devices per driver.

==== Open-source firmware for the FX2 devices ====

The Cypress FX2-based devices, such as the Saleae Logic and the USBee SX, use only a minimal vendor-provided firmware. The only thing it really does is set the sample rate and turn on the chip's auto-mode. Nevertheless, the vendors provide the firmware as a binary blob, with no source.

It would be great if sigrok could ship with an own firmware implementation for these devices. Some links:

* [http://sdcc.sourceforge.net/ SDCC], the Small Devices C Compiler, is a compiler specifically suited to small MCUs, and has support for the 8051 core in the FX2.
* [http://allmybrain.com/2008/12/05/an-open-source-library-for-writing-firmware-on-the-cypress-fx2-with-sdcc/ fx2lib] is an open-source library for writing firmware on the FX2. It has a number of interesting functions, including implementing custom USB vendor commands.
* [http://gnuradio.org/ GNU Radio]'s USRP2 board has an FX2 on it, and GNU Radio has extensive custom firmware for it.

== Windows installer ==

* Add support for downloading/installing the Python Windows installer.

The '''sigrok''' project aims at creating a portable, cross-platform, Free/Libre/Open-Source logic analyzer software that supports various (usually USB-based) logic analyzer hardware products. The code is licensed under the terms of the '''GNU GPL'''.
</div>

== Design goals ==

* '''Broad hardware support'''. Supports a wide variety of logic analyzers from various vendors with different capabilities.
* '''Cross-platform'''. Works on [[Linux]], [[Mac OS X]] and [[Windows]], and on many architectures including x86, ARM, Sparc and PowerPC.
* '''Scriptable protocol decoding'''. Extendable with [[protocol decoders]] and analyzers written in Python.
* '''Format support'''. Supports various [[Input output formats|input and output formats]] (raw, ASCII, hex, CSV, gnuplot, [http://en.wikipedia.org/wiki/Value_change_dump VCD], others).
