Uwe Hermann ec5186f936 hardware/common/dmm: Fix debug output level.
Most messages from the DMM parsers are not hard errors, lower to
sr_dbg() so that the sigrok-cli output doesn't get cluttered (by default)
with debug output such as:

 P1: 0.001100 V DC AUTO
 sr: fs9721: Sync nibble in byte 0 (0x00) is invalid.
 P1: 0.001100 V DC AUTO

(using -l 4 or -l 5 will still allow the user to see such messages)

Uwe Hermann c4f2dfd0f0 configure.ac: libserialport is optional.
Disable drivers that need serial port support if libserialport is not found.

Also, disable building various other serial port related code in that case.

Uwe Hermann 3a8cad9137 metex14: Handle a few missing cases for overflow. 2013-10-31 13:47:30 +01:00
Uwe Hermann c02dc3e261 metex14: Add support for pF (picofarad).
This is used on some Metex DMMs.

Uwe Hermann ee6cb5a417 metex14: Use case-insensitive string compares.
This allows some other DMMs to be supported that use e.g. "kOhm" vs.
"KOhm", and so on.

Uwe Hermann 1a807c13fc metex14: Support DMMs with slightly different protocol.
This adds support for DMMs with 5 digits in the protocol (instead of 4)
and some more whitespace variants.

Uwe Hermann 71f1302b4b metex14: Support DMMs with whitespace differences.
Most Metex DMMs use e.g. "  mV" as unit field, others use "mV  ",
though. Support these (and other) whitespace variants by stripping all
spaces and only comparing non-space characters.

Uwe Hermann a6ed50f405 es51922/fs9721/fs9922/metex14: Use diode MQFLAG.
This fixes #141.

Uwe Hermann 29a27196a1 s/DRIVER_LOG_DOMAIN/LOG_PREFIX/.
This is more correct anyway, and also a bit shorter and more readable.

Uwe Hermann 9871215c83 metex14: Add dB mode and hFE mode support.
This is found e.g. on the Metex M-3640D DMM.

Thanks to Bert Vermeulen for the reminder.

Alexandru Gagniuc 3ebc9b59a2 metex14: Fix parsing of measurement flags.
strcmp(buf + 9, "  mA") does not work because buf is CR-terminated,
while "  mA" is NUL-terminated.

Drop ambiguities arising from the termination of the strings, and
only compare the characters we care about, using strncmp().

Alexandru Gagniuc e82d7dbc20 metex14: Print contents of received packet.
The packet is an ASCII string. We can simply print the raw packet data.

Alexandru Gagniuc 76b55dfa8a metex14: Fix parsing of spaces.
When the parser found a space, it treated it as an invalid digit
and discarded the whole packet. This behavior was incorrect on
2000 count devices, where the first digit can be sent as a space
rather than a '0'.

Convert spaces to '0' and parse them as usual.

Uwe Hermann 1fbab46626 metex14: Pass 'info' as a void pointer.
This is done so that the function prototype of all sr_*_parse() DMM
functions is the same, which will be needed later.
