Uwe Hermann fe0c0b98c6 Add Cyrustek ES51922 DMM chip parser. 2013-01-03 01:13:06 +01:00
Alexandru Gagniuc cbc8cbd8bb rs9lcd: Add missing 'break;'
A break was missing for "case MODE_AMP_WIDTH:" in sr_rs9lcd_parse().

Uwe Hermann 6e9d545cf4 rs9lcd: Fix compiler warning.
rs9lcd.c:289:19: warning: 'rawval' may be used uninitialized in this
function [-Wmaybe-uninitialized]

Alexandru Gagniuc 47eda193b2 rs9lcd: Fix segfault with unusual modes.
Some unusual modes required re-parsing the value. Instead of assigning the
re-parsed value to *floatval, it was reassigned directly to *analog->data;
however, analog->data is not initialized at this point, causing a segfault.
This situation was created when moving the radioshack-dmm code to serial-dmm,
with the segfault not being observed at that time.

Do not write directly to analog->data, but instead use the intermediate
variable rawval.

Alexandru Gagniuc 0853d5e627 rs9lcd: Convenience fixes
Convert bit masks from hardcoded hex values to bit shifts. For example 0x80
becomes (1 << 7). This also fixes a typo error in the definition of INFO_DIODE.

Add comments explaining that some case values in sr_rs9lcd_parse() are meant to
fall through without a 'break;', and explain some of the unusual modes.

Alexandru Gagniuc 21829e6708 radioshack-dmm: Integrate into serial-dmm
Use the infrastructure of serial-dmm to handle the RadioShack 22-812,
and completely remove radioshack-dmm.

Alexandru Gagniuc 05f134abc2 radioshack-dmm: Separate protocol parser from driver
Move the parsing part of radioshack-dmm into a separate protocol
parser, following the model from hardware/common/dmm.

Uwe Hermann 9871215c83 metex14: Add dB mode and hFE mode support.

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.

Uwe Hermann 8c1adf3738 Rework FS9721 parser.
Merge parts of the tekpower-dmm code (the chip of the TekPower
TP4000ZC seems to be an FS9721_LP3 too) and rework parts of the functions.

Adapt the tekpower-dmm and uni-t-dmm code accordingly.

Uwe Hermann 6c701476ad Add protocol parser for FS9721_LP3/FS9721B.
The Fortune Semiconductor FS9721_LP3 and FS9721B/Q100 DMM chips are very
similar and the protocol looks identical.

Tested on a Voltcraft VC-820 (FS9721_LP3) with the uni-t-dmm driver
(needs some small changes, tbd).

Uwe Hermann 79081ec80c Initial support for UNI-T DMMs.
This is not yet fully finished, but works for most use-cases.

Tested with a UNI-T UT61D using the UT-D04 USB/HID cable (new version).
