parse_size_string() incorrectly parses a real number, e.g. 1.5 kHz ends up
being 1Hz.
This patch fixes parse_size_string() to take the fractional part as well into
account. The fractional part is parsed as an double precision floating point
number while ignoring the locale.
(lwla_setup_acquisition): Set the clock divider bypass
flag to 1 for the external clock modes as well.
(capture_setup): Set the clock divide count to 0 if an
external clock source is selected.
(lwla_send_bitstream): Unref the mapped file earlier in order
to simplify the error handling.
(lwla_receive_reply): Do not treat a reply buffer length of
zero as silent no-op. That logic was left over from an earlier
iteration, before the distinction between reply buffer size and
expected read length was introduced.
(lwla_set_clock_source): Checking whether an enum value is greater
than or equal to zero apparently results in a warning with some
compilers. Assign the enum to an unsigned variable to avoid this,
and return SR_ERR_BUG if the range is exceeded, as this indicates
a bug in the driver code itself.
The g_ascii_formatd() function expects the "format" argument to start
with a '%' character, e.g. it should be "%f" or such (this is not
clearly documented in the glib API docs, but visible from the source code).
The usage of "CH%f" for example will trigger an assertion and thus make the
LWLA device unusable in practice (e.g. in PulseView on Windows no probenames
would be shown, and sampling wouldn't work).
Example:
GLib-CRITICAL **: g_ascii_formatd: assertion 'format[0] == '%'' failed
(not exposed in all glib versions or builds of glib on all distros
apparently, some may need G_MESSAGES_DEBUG=all or other measures)
From the glib g_ascii_formatd() code:
g_return_val_if_fail (format[0] == '%', NULL);
We now use g_snprintf() instead for simplicity. This has been tested to
fix this specific issue (i.e. the probenames now do show up in PulseView).
This closes bug #270.
The current implementation is renamed to tcp-rigol as it seems to be
a Rigol proprietary protocol used only on Rigol VS5000 series.
A new tcp-raw implementation is introduced which simply carries raw SCPI
commands over TCP. It is probably a much more common protocol and it is
at least available on Rigol DS2000 series on port 5555.
