Uwe Hermann 545f978639 config.h usage cleanups.
- Drop config.h #include from files that don't actually use any of
   its contents (at the moment).

 - Add comment for those that do need it.

Uwe Hermann b4bd70889f Doxygen: Mark non-public stuff for exclusion.
- /** @private */ can be used for functions, and /** @cond PRIVATE */ and
   /** @endcond */ for variables or #defines.

 - Document the above in HACKING.

Uwe Hermann 6aff0d16df Build fix for Windows/MinGW.
On Window/MinGW 'recv' seems to be already defined in some headers.
Use 'receive' instead, for now.

Bert Vermeulen 161a8a2726 sr: add new analog output module
This outputs text representation of SR_DF_ANALOG packets. Unlike the
float module however, it also outputs the standard abbreviations of
SI units corresponding to the packet's MQ and unit.

It also makes an effort to multiply or divide the floating point value
as needed to the nearest multiple or fraction, and inserts the
appropriate SI prefix to match.

Bert Vermeulen 45c59c8bdd sr: moved sigrok.h so libsigrok/libsigrok.h
All frontends will have to include <libsigrok/libsigrok.h> from now on.
This header includes proto.h and version.h, both installed from the
distribution into $INCLUDE/libsigrok/ as well.

The only dynamically changed header is now version.h, which has both
libsigrok and libtool compile-time versions in it.

Bert Vermeulen 031685005b sr: rename all sr_device_* functions to sr_dev_* 2012-02-13 14:00:47 +01:00
Uwe Hermann 133a37bfba Use g_try_malloc/g_free/g_strdup consistently.
Avoid plain malloc()/free() in sr/srd, especially in the API calls.
Also avoid g_malloc*() in favor of g_try_malloc*().

Use g_strdup() instead of strdup() so that we can use g_free()
consistently everywhere.

Exceptions: Stuff that is allocated via other libs (not using glib),
should also be properly free'd using the respective free-ing function
(instead of g_free()). Examples: Stuff allocated by libusb, libftdi, etc.

Also, use sr_err() instead of sr_warn() for actual errors. sr_warn() is
meant for non-fatal/uncritical warnings.

Uwe Hermann 1a081ca67d sr: Mark API functions with SR_API/SR_PRIV.
Use SR_API to mark public API symbols, and SR_PRIV for private symbols.

Variables and functions marked 'static' are private already and don't
need SR_PRIV. However, functions which are not static (because they need
to be used in other libsigrok-internal files) but are also not meant to
be part of the public libsigrok API, must use SR_PRIV.

This uses the 'visibility' feature of gcc (requires gcc >= 4.0).

Details: http://gcc.gnu.org/wiki/Visibility

Uwe Hermann cd315a80d8 sr/srd: Fix left-over #includes.
The libs themselves should use #include "sigrok.h" etc., while the
frontends must use #include <sigrok.h> and so on.

Uwe Hermann cb93f8a927 Other method to avoid "unused var" compiler warnings.
The '(void)varname' method is nicer than 'varname = varname' and also
prevents warnings when compiling sigrok with clang instead of gcc.

Uwe Hermann 548b08e55c Drop unneeded skeleton files.
They're not too useful as they mostly consist of a list of function names,
and that list is already available in the respective struct. The wiki
API docs and the code in the various hardware/output drivers serve as
useful examples already, no need for additional files.

Uwe Hermann 02604ed6de Initial support for CSV as output format. 2011-04-27 00:25:57 +02:00
Uwe Hermann b53738baf7 Replace g_malloc{0,} with g_try_malloc{0,}.
The g_malloc()/g_malloc0() versions exit/segfault if not enough memory
is available, which is not a good thing in libsigrok.

Instead, we use the g_try_malloc()/g_try_malloc0() variants, which
return NULL if not enough memory is available, so that the caller can
handle the error properly.

Uwe Hermann 50959ddcdc gnuplot output: Optimize by only storing changes.
Only output new lines in gnuplot output if there have been changes in
the samples (similar to what VCD does). As long as the first and last
sample are output, the resulting plot looks OK.

This reduces the size of the output file from roughly 200MB to just 60KB
in one specific test setup (depends on the number of probes and on the
signal, of course). The time and CPU load required to generate the gnuplot
output and the resulting plot (PNG or other) is also drastically reduced
from multiple minutes to roughly 30 seconds (again, depends on various
things).

Thanks Ken Mobley of ChronoVu for the report.

Uwe Hermann b08024a836 libsigrok: Introduce sr_dbg/sr_info/sr_warn/sr_err.
We should use these (internal) functions in libsigrok exclusively from
now on, i.e. no more use of glib's g_debug() etc.

These functions are only for libsigrok, the frontends use whatever
logging mechanism is suitable there.
