Bert Vermeulen e44ac12a29 agilent-dmm: Adjust to GVariant-based sr_config_* functions 2013-04-11 18:32:07 +02:00
Uwe Hermann cd2f0fe22c Add/use std_hw_dev_acquisition_stop_serial(). 2013-02-08 23:32:45 +01:00
Uwe Hermann 6fab7b8f53 Driver struct cleanups.
- Explicitly list .config_get in all drivers for consistency, and set it
   to NULL if unused (whether or not a driver implements it is optional).

 - List all 'struct sr_dev_driver' entries in the same order in all drivers.

 - Move the check whether .config_set/.config_list exist (i.e., are non-NULL)
   into sanity_check_all_drivers().

Uwe Hermann 4afdfd4628 Add and use std_session_send_df_header().
This is a small helper function which sends the SR_DF_HEADER packet that
drivers usually emit in their hw_dev_acquisition_start() API callback.
It simplifies and shortens the hw_dev_acquisition_start() functions
quite a bit.

It also simplifies the input modules which send an SR_DF_HEADER packet, too.

This patch also automatically removes some unneeded malloc/free in some
drivers for the 'packet' and 'header' structs used for SR_DF_HEADER.

Uwe Hermann 961009b0c4 hw_dev_close(): Move common checks to wrapper.
Check the relevant arguments for != NULL before calling the actual
driver-specific function, so that the driver can safely assume those
arguments are non-NULL. This removes the need to duplicate these
checks in every driver.

Uwe Hermann 0e94d524c1 Shorten/simplify hw_dev_list() implementations. 2013-02-05 18:27:05 +01:00
Uwe Hermann 063e7aef6d Factor out common hw_init() driver code.
Most drivers do pretty much the same things in their hw_init()
right now, so factor out that code to std_hw_init() in std.c.

Bert Vermeulen 6a4710fac2 drivers: Trim unused config_get() calls
None of the driver config_get/set/list calls are required.

Bert Vermeulen 0d485e30c6 Deprecate SR_DI_HWOPTS.
This is replaced by SR_CONF_SCAN_OPTIONS.

Bert Vermeulen 9a6517d14b Deprecate SR_DI_HWCAPS.
This is replaced by SR_CONF_DEVICE_OPTIONS.

Bert Vermeulen a1c743fc51 drivers: implement config_list() 2013-01-25 02:37:26 +01:00
Bert Vermeulen 035a1078fd drivers: rename and reorganize config get/set
The driver API calls info_get() and dev_config_set() have been renamed
to config_get() and config_set(), respectively.

Bert Vermeulen 1953564a96 Rename SR_HWOPT_* and SR_HWCAP_* to SR_CONF_* 2013-01-21 23:32:50 +01:00
Bert Vermeulen 1987b8d63e drivers: use new sr_config struct
Sending an SR_DF_META packet at the start of every stream is not
mandatory; the frontend should ask for what it needs, and any extra
information the driver wants to send will come in due time.
2013-01-21 23:32:49 +01:00
Uwe Hermann 4ebd48b352 Remove non-error hw_info_get() messages.
Currently hw_info_get() can receive requests for entries (info_id) that
the specific driver doesn't support. That is (right now) a valid
use-case and not an error (might change later, though).

Thus, for now, don't output messages for such requests at all (certainly
not as sr_err() where they show up in e.g. sigrok-cli output per default).
2013-01-20 18:48:02 +01:00
Bert Vermeulen 6b8d6f93bb Get rid of obsolete SR_DI_NUM_PROBES and SR_DI_PROBE_NAMES.
Frontends should use the probe list in the device's sr_dev_inst
to get this information.

Peter Stuge 1ebe4b4e69 hw_init(): Save struct sr_context * parameter in struct drv_context 2012-12-03 12:07:40 +01:00
Peter Stuge 34f06b903e Add a struct sr_context * parameter to hw_init() 2012-12-03 12:07:40 +01:00
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 74ac7d7f73 agilent-dmm: no need to specify a serialcomm scan parameter
It's always 9600/8n1 anyway.

Bert Vermeulen 69b07d14db allow for intermediate stage in stopping acquisition
In the case of USB drivers, a driver's dev_acquisition_stop() cannot
simply remove its fd sources from the session and close its devices:
a USB transfer might still be underway, and it needs to be finished
(and its memory freed) properly.

An sr_dev_inst->status value is added: SR_ST_STOPPING, which should
be set when the driver's dev_acquisition_stop() is called, and acts
as a marker for the USB event handler to wind up its operations.

In order for dev_acquisition_stop() to be able to set the sdi status,
however, it needs to be unconstified.

Uwe Hermann 886a52b6fb Return SR_ERR_MALLOC upon allocation errors.
Add some TODOs.

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 545f978639 config.h usage cleanups.
- Drop config.h #include from files that don't actually use any of
   its contents (at the moment).

 - Add comment for those that do need it.

Bert Vermeulen 8c0152f29b agilent-dmm: tentative support for all U123x and U125x models
Only tested on U1233A, but it just might work.

The U125x protocol decoding only supports voltage, current, resistance,
capacitance and diode measurements for now.
