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.
This is found e.g. on the Metex M-3640D DMM.

Uwe Hermann ce3777ada9 serial-dmm: Add Metex ME-31 support. 2012-12-02 14:22:46 +01:00
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 a54dd31e38 serial: Use OS-independent flags for serial port opening.
Add SERIAL_RDWR, SERIAL_RDONLY, and SERIAL_NONBLOCK (for now), which are
mapped to the respective OS-specific mechanism in serial_open().

Bert Vermeulen 71caaad46b serial: allow for extra rts and dtr options in conn string
Options in addition to the usual "9600/8n1" syntax start with a
slash, and take the form of key=value, where different options are
also separated by slashes. For example:

	"9600/8n1/rts=0/dtr=1"

This sets RTS low and DTR high.

Bert Vermeulen 299bdb249e serial: revamp internal API
The only thing to get passed around now is the struct sr_serial_dev_inst
pointer. This should make things more portable as well.

Alexandru Gagniuc a99e0d2a0c ols: Do not randomly probe serial ports
ols driver used to probe a series of available serial ports obtained
by regexp matching of common serial port names.
There are a number of problems with this approach:
1. It will probe all serial devices, including devices that do not
like to be probed, potentially causing them to act up.
2. It will try to probe serial ports which may already be opened in
other applications for other purposes.
3. It assumes the naming of the serial ports is set in stone, and
creates an unnecessary OS-specific list.
4. It produces unnecessary debug output even when an OLS device is
not connected.
5. etc...

Do not implicitly probe serial ports. Only probe the port specified
by the frontend, if any; otherwise, just quit.
Also get rid of all functionality in serial.c which was designed
specifically for random probing.

Uwe Hermann 0c632d36be genericdmm: Factor out USB functions.
Move sr_usb_connect() and sr_usb_open() to hardware/common/usb.c in a
slightly more generic form and add more error checks and logging.

Let genericdmm use the new/moved functions.

Uwe Hermann b19f4622b6 serial: More error-checking & logging, add baudrates.
This mostly affects the non-Windows code so far, the rest will follow.

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 6f22a8ef2c Factor out serial_readline() to serial.c.
Only one (slightly different) variant remains in agilent-dmm, this will
be merged soon too, though.

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).

Bert Vermeulen 47211d65b4 sr: add probe list to device instance
There is no point in libsigrok copying probe lists around. The driver now
builds a list of probes according to the model device it found, and will
make that available to a frontend. The frontend thus has a reference of
what the driver has, including default names, and doesn't need libsigrok
to provide an unnecessary level of abstraction.

The sr_probe_new() library-private function is a helper for drivers.

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.
