Also use "r" and "f" as trigger slope values for now, since that's
what most other drivers do currently.
This also fixes two scan-build issues:
api.c:559:3: warning: Value stored to 'tmp_str' is never read
tmp_str = g_variant_get_string(data, NULL);
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
api.c:561:9: warning: Use of memory after it is freed
ret = siglent_sds_config_set(sdi, "%s:TRSL %s",
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The strcasestr() function is non-portable (e.g. not available on
MinGW, possibly elsewhere). Replace it with g_strstr_len() for the time
being. While the latter is not case-insensitive it appears that
that property doesn't matter here ("." should not be relevant anyway,
and e.g. an SDS1202X-E does indeed report "Mpts" as such).
Should it become necessary to have this code be case-insensitive,
we'll have to find a more portable solution than strcasestr().
This causes some compile errors on platforms where RPC is not available, e.g.
siglent-sds/api.c:25:21: fatal error: rpc/rpc.h: No such file or directory
Surrounding the #include (and later code) with "#if HAVE_RPC" should avoid
these compile errors, but since it's not used at all for now, drop it.
Implement a first version of the driver for the Siglent SDS1000 and
SDS2000 oscilloscopes.
[ gsi: This commit corresponds to git 0228126017e6 of marchelh's tree,
I adjusted the source to closer match the project's coding style. The
conversion was verified by this command:
$ git diff --word-diff=color -w -b <branch>:<dir> <branch>:<dir>
Changes include: Whitespace adjustment, dead code removal, separation
of variable declaration and assignment, alpha-sorted includes. Line
length was not addressed and not every location got adjusted, to keep
the diff minimal and to reduce effort during review of this version. ]
